2.1 Rack Configuration
Various rack widths are available, supporting different numbers of slots for card installation. Typically a
903 rack has 2 slots for video cards, 1 slot for the FMB-X-2.5, 3-4 slots for data cards, and 1 slot for a
Eurocassette PSU. Many remote racks substitute a DC-DC module on the back cover in place of the
Eurocassette PSU to reduce the width of the rack by 8 HP (4 HP = 0.8" or 20.3 mm). The remote rack
usually has a wire pigtail for applying AC or DC power; the console rack generally has a front panel
switch and an IEC-320 jack on the rear cover to support a variety of plug cables. Console modules can be
provided in full 19" racks or as reduced width sub-racks with add-on flanges for installation in 19" racks.
Slots in each rack are referenced by letter, per the installation drawings. Slots A and B are 4 HP wide and
are intended for video cards, slot C is an 8 HP slot for the FMB-X-2.5, slot D and above are typically 4 HP
wide data slots with the exception of the last slot, which is usually 8HP for the power supply module. The
console module usually includes an additional panel for the power switch.
Some racks include one or two slots dedicated for media converter cards. Thes e slots provide only power
at the backplane connectors, since the media converters do not require any backplane data lines. Media
converters may also be installed in data slots, which in this case the backplane data lines are unused.
Optical expansion cards, such as CWDMs may be installed in any video, data or media converter slot.
Refer to installation drawings 903-8XXX-XX for the actual as-built rack configuration.

2.2 Electrical Configuration
The following figure shows the signal configuration of a Model 903 system. Each video card
"pre-multiplexes" four video channels on 10 video lines to the FMB-X-2.5 resulting in 10-bit digitization for
each video channel. Each data card slot has 5 lines on the backplane to and from the FMB-X-2.5. In total
there are 20 data lines. Some data cards, such as the AIB-4, map a single data input to a single data line
to the FMB-X-2.5. Other data cards, such as the CIB-10 and DIB-232-16, map several data channels to a
single line to the FMB-X-2.5.

2.3 Optical Configuration
Model 903 systems based on FMB-X-2.5 cards are provided in standard optical configurations with
singlemode fiber and dual fiber connection for redundancy. Typical systems u se 1310 nm as the uplink
wavelength (remote to console) and 1550 nm as the downlink wavelength (console to remote), which are
combined with a wavelength division multiplexer (WDM) on the FMB-X-2.5. Dual fiber configurations
increase reliability with an integrated splitter at the remote FMB-X-2.5 and an automatic fiber switch at the
console FMB-X-2.5, as shown in the figure below.
Figure 2.3-1: Model 903 Fiber Optic Transmission System
Standard FMB-X-2.5 cards use lasers with loosely controlled wavelengths that can vary significantly from
unit to unit and over temperature. Since 1310 nm and 1550 nm are widely separated on the optical
spectrum, there is no problem with crosstalk or interference even when the exact wavelengths are
variable.
FMB-X-2.5 cards are also available with more carefully controlled wavelengths for use in multi-channel
systems based on CWDM (Coarse Wavelength Division Multiplexing) or DWDM (Dense Wavelength
Division Multiplexing). CWDM systems support 4 to 16 wavelengths; DWDM systems support 16 or more
wavelengths. Both CWDM and DWDM enable the combination of two or more FMBs, plus other media
converter cards, on a single optical fiber, allowing considerable expansion of the Model 903 video and
data channel capacity.
Focal Technologies Corp. Page 2-5
903-0623-00 Rev. A Model 903 User's Guide, FMB-X-2.5 Version
CWDM wavelengths may be used to expand an existing Model 903 system by adding separate optical
links, typically for high-speed sonar, Gigabit Ethernet or HD-SDI Video. Daisy-chaining media converter
cards (cards with on-board optical transceivers using CWDM wavelengths) into the existing
1310/1550 nm optical link allow the upgraded system to continue operating on a single fiber. Media
converter cards such as the ECL-02, EIB-10/100 (optical version) or HD-SDI may be installed in any data
card slot.
The figure below shows an example of an expanded Model 903 fiber optic transmission system using
media converter cards with CWDM wavelengths. In this example, the remote and console media
converter cards are “daisy chained” into an existing 1310/1550 nm system and four waveleng t hs are
used. The media converter card uses 1471 nm and 1491 nm wavelengths and the FMB-X-2.5 card uses
1310 nm and 1550 nm wavelengths. Note that the 903 system continues operating on a single fiber
(second fiber is optional). Refer to section 6.0 for more information about the media converter cards
available for Model 903 systems.
Figure 2.3-2: Model 903 Fiber Optic Transmission System Expanded
Systems that require more than four wavelengths must use a dedicated CWDM card to combine all
wavelengths. (Also all transceivers must be CWDM wavelengths.) Optical configuration drawings are
provided for systems with more than two wavelengths.

3.0 Fiber Multiplexers and Backplanes
Fiber Multiplexer Boards (FMBs) are used to combine all of the video, Ethernet, and data signals into a
single optical link and then regenerate the original copper signals at the other end of the system.
Backplane cards are used to connect all of the Model 903 cards together within remote or console
modules. A complete Model 903 system includes at least one remote and one console module.
3.1 FMB-X-2.5 Fiber Multiplexer Board
The FMB-X-2.5 cards use FPGA SERDES (Serializer/Deserializer) modules that run at an optical data
rate of 2.5 Gbaud on both uplink and downlink. This high optical data rate allows more capacity for video,
data and Ethernet traffic than older FMBs. FMB-X-2.5 cards are designed to work only with singlemode
fibers to support the high data rates. System diagnostics can be accessed via the RS-232 port or RJ-45
Ethernet port of both remote and console FMB-X-2.5 cards. More information about diagnostics is
provided in Appendix D and the diagnostics manual (P/N 903-0622-00).
Note: The FMB-X-2.5 FPGA-based SERDES optical link is not backwards compatible with FMB-VTX,
FMB-VRX or GLINK FMB-X cards. More details about upgrading to FMB-X-2.5 are found in Appendix C.
Details on the GLINK-FMB-X cards are given in Appendix D.
3.1.1 Remote FMB-X-2.5
Card P/N 903-5082-00
The front panel view of the remote FMB-X-2.5 is shown in the figure below. Redundant ST fiber
connectors are accessible on the right angled turret. An internal splitter provides roughly equal powe r
output levels on both ST connectors. Output power should be greater than -6 dBm at 1310 nm (uplink).
Receive sensitivity at the turret should be better than -26 dBm at 1550 nm (downlink). Front panel LEDs
provide critical status indicators described in detail in section 3.1.2.

LEDs on the front panel match those described in the console FMB-X-2.5 section and allow direct
monitoring of the optical link status (LINK), optical receive power (FO-RX), and the status (STAT) of the
on-board diagnostics. See the console FMB-X-2.5 section for more details on LEDs.
The Ethernet port supports both 10 Mbps and 100 Mbps devices on the copper link. The optical Ethernet
link through the multiplexer is 100 Mbps.
Diagnostics for the FMB-X-2.5 can be accessed at the RS-232 port on both remote and console cards,
and also via the RJ-45 Ethernet port at both remote and console ends. See console FMB-X-2.5 for more
information about diagnostics.
A plan view of the remote FMB-X-2.5 is shown in the figure below. The 1310/1550 nm singlemode WDM

LEDs on the front panel of the remote or console FMB-X-2.5 provide status of video channels, optical link,
and card health per table below.
LED Description
VIDEO
VIDEO LEDs are green when video sync is detected on each video channel from slot A
and slot B in the rack.
LINK LINK LED is green when a valid optical link is being received and red if no link is present.
FO-RX LED is green when the received optical power is well above threshold. This LED
FO-RX
will change to orange (warning), indicating low margin, or red (alarm), indicating low optical
power. Problems with optical power should be investigated using the diagnostic software
and/or fiber optic power meters.

Table 3.1-1: FMB-X-2.5 Front Panel LEDs
903-0623-00 Rev. A Model 903 User's Guide, FMB-X-2.5 Version
LED Description
STAT (Status) LED is green when on-board diagnostic readings are within expected
values. The STAT LED is orange (warning) if any of the on-board diagnostic readings are
close to an alarm state. The STAT LED is red (alarm) if any of the on-board diagnostic
readings are outside of the specified range, in which case the diagnostic software shoul d
STAT
be used to troubleshoot the problem. Monitored signals included temperature and all major
voltage rails (+12V, -12V, +5V, and +3.3V). An alarm state exists if any voltage is worse
than ±20% of nominal value or temperature is > +80C. A warning state exists if any
voltage is worse than ±10% of nominal value or temperature is > +75C, but the reading is
not in an alarm state.
F1/F2 LEDs indicate which fiber is active, per the marked ST bushings. The active fiber is
F1/F2
shown by the green LED. (Toggle up forces the fiber switch to F1 and toggle down forces
it to F2.) The LED(s) will turn red if no link is present.
AUTO
AUTO LED is green when the fiber switch is in automatic mode, as determined by the
toggle switch position. When in automatic mode and there is no link, this LED will be red.
Diagnostics are available at the 1/8" (3.5 mm) stereo jack in RS-232 format compatible with the standard
Model 903 Diagnostics GUI software, e.g. 903-0406-00. Wiring for the RS-232 connections is shown in
the table below.
Table 3.1-2: RS-232 Diagnostic Port Connections
Stereo Jack Pin DB-9F pin Function
1 (Tip) 3 TXD
2 (Middle Ring) 2 RXD
3 (Base Ring) 5 SIG GND
The function described in the table above is relative to the PC, i.e. TXD is data transmitted from the PC to
the FMB-X-2.5 and RXD is data received into the PC from the FMB-X-2.5. This RS-232 interface also has
command based diagnostics, which provides advanced diagnostics information. See 903-0622-00
diagnostic manual for more information.
Diagnostics are also available via the RJ-45 port as Modbus TCP/IP or through an embedded web server.
Since this port is also used for general Ethernet traffic between remote and console, diagnostics packets
are handled as low priority and must be polled by the external computer. When accessed, diagnostic data
packets typically use up less than 0.1% of the Ethernet channel capacity.
The fiber switch may be placed in automatic mode or forced to fiber F1 or F2 using the front panel toggle
switch. In automatic mode, with the toggle switch in the center position, the FMB-X-2.5 tests both fibers
on initial power up and chooses the one with the highest optical power. This will stay locked until the
switch is forced to the other fiber, via the toggle switch, or link is lost on the active fiber. The LED by F1 is
green when that fiber is active – the same applies to F2. The LED marked "AUTO" is green when in
automatic switching mode.
When the optical link is lost, in auto mode, the switch toggles automatically roughly once per second
between F1 and F2 for up to 10 times. If no link is found, the switch returns to the original fiber it was on
before the link failure and waits for a link to be re-established. In this state, the “AUTO”, “F1” and “F 2”
LEDs are red and a continuous audible alarm is produced until a fiber link is restored. Power cycling or
manually forcing the toggle switch to a fiber (F1 or F2 position) and then back to AUTO will reset the
automatic fiber switch.
The FMB-X-2.5 also sounds a continuous audible alarm when an optical link fails in AUTO mode, even if
the other fiber has a valid link. This informs the operator of a fiber fault that otherwise might not be
noticed, as the switchover from one fiber to the other is often seamless. The alarm can be turned off by

briefly forcing the toggle switch to the active fiber in manual mode and then back to the automatic setting.
The FMB-X-2.5 alarm can also be disabled via software commands.

FRONT PANEL
4.0 Video Cards
This section contains information about the video cards that can be used in a Model 903 system.
Typically the video cards are inserted in slot A and slot B of the 903 rack.
The VIB-X video interface board is a generic, 4-channel video card for use with Model 903 multiplexer
systems.
The VIB-X cards are designed around an FPGA (Field Programmable Gate Array) connected to four input
circuits for digitizing video channels and four output circuits for regenerating analog signals from the
digital samples. Switch settings on the VIB-X select the code loaded into the FPGA on power up, which
sets the front panel jacks as either video inputs or video outputs. Additional switches determine the
formats of the input/output signals. Video signals are digitized in 10-bit samples at 15.625 MHz with
FMB-X-2.5 cards.

Figure 4.1-1: Block Diagram of VIB-X Card
The VIB-X video interface board is configured with four SMB video jacks on the front panel, per Figure
4.1-2. This 3U Eurocard is switch configured as either a video input card, used in the remote or subsea
multiplexer module, or a video output card, used in the console or surface multiplexer module. The
current setting can be verified by the front panel LEDs marked "Remote" or "Console" indicating whether
the card is operating as a video input (remote) or video output (console).
Note: VIB-X cards shipped before August 2011 only support LED diagnostics but do not suppor t
enhanced diagnostics, which provides card serial number information and a video test pattern
generator.
Focal Technologies Corp.Page 4-1
903-0623-00 Rev. A Model 903 User's Guide, FMB-X-2.5 Version
Figure 4.1-2: VIB-X Front Panel
The VIB-X replaces the older video cards VIB-TX and VIB-RX, including filter daughtercards, with a single
assembly that is switch configured to behave as a VIB-TX card (video input) or VIB-RX card (video
output). VIB-X cards are backwards compatible with the older VIB-TX and VIB-RX cards and may be
paired with them for standard video signal formats. Although designed to take advantage of -X
backplanes, VIB-X cards are also backwards compatible with older Model 903 backplanes. The only
difference between the VIB-X versions of VIB-TX and VIB-RX cards is the factory switch setting.
4.1.1 Input/Output
VIB-X video inputs and outputs are compatible with standard composite signals (NTSC, PAL), Y/C or
S-video formats, and component video formats RGB (sync on G) and YPrPb. Inputs and outputs have
75-ohm impedance with ESD protection and should be used with high quality, 75-ohm coaxial cables,
such as RG-179. Mating connectors should be "Mini" 75-ohm SMB plugs, though 50-ohm SMBs are
compatible and acceptable for video bandwidth signals. Inputs should be standard video levels, typically
1.0 to 1.2 Vpp. Signals will start to clip at 1.4 Vpp, and absolute maximum levels are 3 Vpp. Input
bandwidth is limited to 6 MHz by anti-aliasing filters.
Focal Technologies Corp. Page 4-2
903-0623-00 Rev. A Model 903 User's Guide, FMB-X-2.5 Version
4.1.2 Configuration Settings
The VIB-X is configured as a remote (video input) or console (video output) using switch SW3, as shown
in Figure 4.1-3 and Table 4.1-1. Circuit 1 is used to set the card as video input or output and circuit 2 is
used for setting normal operation (mux mode, default) or for factory test options (test mode).
ON ON Loop-Test Mode: Ch 1 In to Ch 3 Out; Ch 2 In to Ch 4 Out
OFF ON Loop-Test Mode: Ch 3 In to Ch 1 Out; Ch 4 In to Ch 2 Out
Input and output video formats are configured with switch SW1 per Table 4.1-2. Switch SW2 is not
required for the VIB-TX and VIB-RX configurations of the VIB-X card, and all SW2 circuits should be in
the OFF state. Note that in Y/C modes, “Y” (luma) must be connected to channel 1 to provide sync to “C”
(chroma) on channel 2, and for dual S-video mode, “Y” must be connected to channel 3 to provide sync to
“C” on channel 4. In RGB or YPrPb mode, the sync on “G” or “Y” must be connected to channel 1 to
provide sync to channels 2 and 3. Switch configurations for video format on the remote and console
video cards must match.
Remote Configuration (Video input, e.g. video signal from
camera is connected to this card)
Console Configuration (Video output, e.g. video signal from this
card is connected to a monitor)

903-0623-00 Rev. A Model 903 User's Guide, FMB-X-2.5 Version
Figure 4.1-3: VIB-X Plan View
Fuses on the rails from the backplane provide over-current protection near the 96-pin DIN 41612
connector at the back of the card, per Figure 4.1-3. Fuse F1 is a 3A fuse on the +5 V supply rail and fuse
F2 is a 1A fuse on the -12 V rail, which is used to generate -5 V on the board. These fuses are soldered
in place and are not intended to be field replaceable, as any over-current fault sufficient to blow a fuse
can potentially damage the VIB-X card. Cards with blown backplane fuses should be returned to Focal for
assessment.
The sync status of each video channel is represented by the sync LEDs on the corresponding FMB-X-2.5
modules. Furthermore, for 903 systems that have both the FMB-X-2.5 and backplane -X cards, the
diagnostics software at the surface can monitor the status of the remote VIB-X card, includin g input
voltage overload flags, current video format configuration, and card assembly information, such as serial
number. A black and white bar test pattern is also available on the VIB-X at either the remote or the
console through the diagnostic software (command mode). This test pattern is generated in the FPGA
and at the remote end this test pattern can be output at the front panel as well as to the backplane, and at
the console end the test pattern can be only output to the front panel. Refer to FMB-X-2.5 diagnostics
manual (P/N 903-0622-00) for more details.
Note that VIB-X cards do not support "non-video" signals on channel 4, as with older VIB-TX and
VIB-RX cards. Typically the "non-video" signals were audio or special high speed sonar signals,
which are now handled by other card types. Please consult Focal for any non-standard vi deo
signals or switched video configurations.

5.0 Data Cards
Data cards are typically bidirectional, with some exceptions. Most data cards are interchange able
between the remote and console module.
5.1 DIB-232 - RS-232 Interface Board
Card P/N 903-0016-00
The DIB-232 card is obsolete, and this section is for information only. RS-232 channels for ne w
systems can be provided by other cards, such as DIB-232-16, AIB-4 and 907-232E.
The RS-232 Data Interface Boards (DIB-232) support bidirectional RS-232 signals. DIB-232 cards may
be used at either end of the system in any available data slot. RS-232 signals are limited to 120 kbaud.
5.1.1 Input/Output
The five front panel connectors, as shown in Figure 5.1-1, are all three pin, right angle, 733 series WAGO
connectors (mate: WAGO 733-103). All five channels are separately isolated and can operate to a
maximum bit rate of 120 kbaud. All channels are protected by 250 mA fuses and transient voltage
suppression diodes. One spare fuse is provided on the board. The black dot at the top of the front panel
marks channel 1.
LED indicators are provided for each DIB-232 channel. T denotes data transmitted out of the DIB board’s
front panel connection as indicated by the green LED. R denotes data received by the DIB-232 board as
indicated by the red LED.
