x OTS9100 User Manual

Getting Started

This chapter describes the preparation and initial setup of the OTS9100 module. Also provided
is a list of standard and optional accessories for each of the individual cards.

Product Description

The Optical Test System OTS9100 Module set consists of a 10 Gb/s SONET/SDH transmitter
and receiver. The transmitter consists of a high-speed OC-192c/STM-64c SONET/SDH digital
signal generator feeding a 10 Gb/s fiber-coupled laser and modulator. It is capable of generating
fixed and pseudo-random test patterns mapped into a set of sub-rate payloads or one full payload
rate. The transmitter may also retransmit received 10 Gb/s signals with or without alarm and
error insertion via intrusive through mode capabilities. Both transmitter and receiver support
Unframed Mode. The transmitter supports flexible generation of alarms and errors at SONET
and SDH levels (SONET Section, Line and Path; SDH Regenerator Section, Multiplex Section
and Path).

The receiver consists of a high-speed 10 Gb/s (9.9532 Gb/s) optical receiver feeding an OC­192c/STM-64c digital signal analyzer. The receiver supports both SONET and SDH (SONET
Section, Line and Path; SDH Regenerator Section, Multiplex Section and Path) alarm and error
detection and accumulation for subsequent software analysis with the ability to print out reports.

The standard OTS9100 module consists of one each of an OTS91L4, OTS91R2, OTS91T3 and
OTS91C3 card. A mixed suite of optical cards provides the OTS9100 module with flexibility to
test for different optical requirements.

The OTS91L4 Transceiver card is the standard optical card for this module. The OTS9100
module will accept any of the OTS optical cards as a replacement for the OTS91L4, expanding
the range of the system to support different types of test analysis. The only requirement is that
the optics card be placed in the first slot position within the OTS9100 module.

Optical card offerings consist of the following:

OTS91L4 Transceiver with 1550 nm or 1310 nm laser option

OTS91L5 Transmitter with 1550 nm or 1310 nm laser option

OTS91L6 Receiver Only

OTS91L7 Transceiver with External Laser Interface (does not include an internal laser)

OTS91L8 Transmit Only with External Laser Interface (does not include an internal laser)

First Operation

OTS9100 Installation

Before using the system, verify that it is properly set up and powered on, as follows:

1. Remove the unit from its shipping carton and place it on an anti-static surface.

2. Verify that the operating environment is within the limits detailed under the Environmental

Requirement section in this manual.

3. Allow approximately 2 inches (5 cm) clearance for cooling at the front and rear of the unit.

The fans draw air into the system from the front and exhaust the air through the rear of the
OTS9000 chassis system or through the sides of the OTS9010 and OTS9040 chassis systems.

4. If the module cards are not already installed, perform the following steps:

CAUTION! When installing and removing cards from the chassis, power must not be present.
Ensure that all power switches are in the OFF position and power cords are not installed
before removing or installing cards. The chassis does NOT support hot-swap installations.

Getting Started

A. Remove the cards from the packaging, if necessary.

CAUTION! All OTS cards are static sensitive. When handling cards, ensure that personnel
are properly grounded and OTS cards are always placed on anti-static surfaces. If proper
precautions are not taken, damage will occur.

B. For those locations in which cards are being installed, remove the blanking panels and air

diverters.

C. Verify the required configuration of cards before proceeding. Carefully install each card

into a slot in the chassis. Make sure that the card is lined up and fits cleanly with the
connectors into the backplane of the chassis.

CAUTION! Beware of bending the pins of the connectors when installing and removing cards
from the chassis. Backplane connectors with bent pins will cause damage to both the card
and the chassis.

To install the card, slowly slide the card into the desired slot. Make sure the card is lined up with
the connectors and push down on the top release and up on the bottom release until the card
snaps into place.

OTS9100 User Manual 1-7

Getting Started

When the card is in place, tighten the two screws to secure it.

CAUTION! Do not torque the screws with more than 2 in-lbs of force or damage will occur.

5. Verify that the power switch of the OTS chassis is in the OFF position.

6. Plug the unit into the appropriate AC Power source as follows:

Table 1-4: Power Requirements

AC Voltage Voltage Range Frequency Range

110 VAC 90 VAC - 132 VAC 48 - 62 Hz
220 VAC 180 VAC - 250 VAC 48 - 62 Hz

Removing Cards

To remove the OTS cards, perform the following steps:

1. Turn off the power.

2. Fully loosen the two screws found on the top and bottom of the card.

3. Push up on the top release and down on the bottom release until the card is released from the

connectors.

4. Carefully slide the card out of the slot.

NOTE: If a card is removed, a blanking panel and air diverter must be installed to ensure
proper airflow through the system. Failure to replace the air diverter and blanking panel could
cause the system to overheat.

1-8 OTS9100 User Manual

Slot Positioning of OTS Cards

The slot in which each card is installed is very important to the proper operation of the
instrument. Because of the user interface configurations, certain cards must be in specific slot
positions in order to take advantage of features to operate correctly.

The OTS9100 module consists of a grouping of four cards. For every OTS9100 module group,
the Optics card must be in the leftmost card or slot 1 (Does not apply to a multi-channel system).
The Optics card must be followed by the Receive card in the second position, the Transmit card
must be in the third position and the Clock Trigger card must always be in the right-most position
or fourth position within the four card module grouping.

Multiple Modules

A module group may span the CPU in a multi-module system if necessary. The sequence of
cards should continue from one side of the CPU slot(s) onto the other side. The CPU card(s) may
interrupt the sequence physically but does not end the module group. Slot positioning with the
CPU interrupting a sequence of cards will not affect the functionality of the OTS cards on either
side of the CPU slot position(s). Empty slots, or slots containing non-Tektronix cards; effectively
‘end’ the module group.

Getting Started

When an OTS9100 10 Gb/s module and an OTS9200 Jitter module are loaded within the same
chassis the slot positioning must start with the OTS9100 optical card positioned in the first
position with the rest of the OTS9100 module loading sequentially as described above, the
OTS9200 module must be adjacent to the OTS9100.

Through Mode operation is only supported when the module has been loaded into slots 1-4 of the
chassis and only when the modules are installed in the following order:

• Optics card is in slot 1

• Receive card is in slot 2

• Transmit card is in slot 3

• Clock Trigger card is in slot 4

If cards are not installed in this order, “through mode” is not allowed as a Tx Signal Source.

NOTE: If the slot positioning rules are not followed, the module functions will be invalid. The
transmitter and receiver functionality depends upon the absolute slot position and relative order
of the cards.

Laser Lockout, Remote Interlock

REMOTE INTERLOCK is a bantam plug normally closed connection internally wired in series
with the laser lockout key switch. It can be used with additional hardware to remotely disable
the laser output.

NOTE: If this connection is used, the ferrite bead provided with the module must be attached to
the remote interlock cable for lower emissions and CE mark conformance. Install the bead close
to the end of the cable connected to the Optics card.

Laser LOCKOUT is a safety device. The key switch disables the laser output when it is turned
to the “closed lock” position. The laser output can only be turned on when the key is in the
“open lock” position.

NOTE: The laser output cannot be enabled unless:

• The Laser Lockout key switch is set to the “open lock” or on position.

• The Remote Interlock is either not used or externally enabled.

• The Laser output is software enabled.

NOTE: Optical cables use and care

1. When using the optical cables ensure that the cable is firmly seated in the front panel

connector. The optical connectors on the front panel are keyed. If the cable is not inserted
into the connector key properly, the connection between cable and front panel will not be
complete and so will cause errors in transmission and receiver functions.

Software Interface Operating Basics

This section describes the OTS9000 software interface. It also reviews the basic functionality of
the Microsoft Windows application software with menu descriptions.

User Interface

The user interface software for the OTS Family Optical Test System controls all configuration,
testing, and measuring commands of the OTS cards. The user interface provides easily navigated
menus using Windows® ‘point and click’ operation on a Windows 2000 workstation.

Refer to the section, Getting Started, for information on how to load and launch the user
interface software.

When the OTS Optical Test System is first powered on the software scans the card slots to
determine what modules are loaded. The user interface then provides icons in the navigation
window for each card loaded into the system. These icons always reflect the cards loaded and
will change depending on the system being used. Because of this ‘on the fly’ software feature,
some of the menus and abilities described in this manual may not be available in all systems
since many features require a particular card installation. In addition, some of the menu screens
may appear different from those displayed in this manual.

The user interface screen has a number of windows and bars that comprise the main screens of
the software, some of which may be disabled. The next section, Elements of the User Interface,

J0 Multi-Byte Trace

J0 Trace provides a capability to uniquely identify each of the multiple channels being carried in
a Dense Wave Division Multiplexer (DWDM) system, providing an end-to-end continuity check.
Since only the SONET framing byte plus J0 are in the unscrambled overhead of the SONET
signal, it is possible to extract for display the J0 trace to confirm channel ID.

The OTS9100 has the ability to generate unique J0 traces. This allows test signals to be easily
identified, or to simulate network-element generated traffic without the Trace Identifier
Mismatch (TIM) alarm being generated. The OTS9100 capability to display the received J0 trace

J1 Multi-Byte Trace

J1 Trace provides a capability to uniquely identify each of the multiple channels being carried in
a Dense Wave Division Multiplexer (DWDM) system, providing an end-to-end continuity check.
It is possible to extract for display the J1 trace to confirm channel ID.

The OTS9100 has the ability to generate unique J1 traces. This allows test signals to be easily
identified, or to simulate network-element generated traffic without the Trace Identifier
Mismatch (TIM) alarm being generated. The OTS9100 capability to display the received J1 trace

Transmitter - IP Payload

The new Packet Over SONET (POS) feature characterizes physical layer performance of SONET
and SDH equipment by generating and measuring IP traffic.

Specifically, the POS feature provides the ability to determine physical layer operating limits
based on IP QoS. For instance, the sensitivity of IP routers to received laser power, optical jitter
tolerace, degraded Signal to noise, and frequency offset can be determined using IP
measurements.

The principle benefit of this additional feature is confidence that IP QoS is not preturbed by
conforming physical layer degradations. The POS feature is not intended to be a comprehensive
IP QoS tester but to enhance physical layer testing.

and a Selected View. If Selected is chosen, a window is displayed, which allow the user to select
four error measurements.

Receiver - Cumulative

The cumulative menu has two selections on the top for Display choices, Section and Line, and
Path. The cumulative display menu provides a summary of the errored seconds, error counts, and
error ratios for each error condition monitored during the test. The results are accumulated while
the test is in progress and are cleared when a new test begins. The measurements shown reflect
the display choice, as shown in Figures 2-44 and 2-45.

The upper window shows a trace for each measurement parameter. A dark rectangle is shown for a

measurement interval during which an errored second occurred (LOS, LOF, LOP, SEF/OOF, TIM, AIS,

RDI, PLM, UNEQ, LSS) or one or more errors were counted (B1, B2, B3, FAS, REI, BIT/TSE).

The lower window shows a bar-graph display (B1, B2, FAS, REI) of the anomaly selected by
the Detail View selector. The display may be linear or logarithmic, and is automatically scaled
based on the maximum value for that parameter.

The Zoom Out/In slider sets the display’s time axis. The limits are 1 second/tick to 1 hour/tick.
The display and the detail view scale are set accordingly.

The Scroll bar scrolls the display horizontally.

The display Time Axis may be set to show elapsed test time or time of day. Elapsed test time
does not accrue when a test is paused; time of day continues.

The Cursor, shown as a colored line on the display, identifies a particular measurement sample.
It may be positioned in several ways:

 Incrementally, by moving it with the four Cursor buttons

 Directly, by clicking the mouse in one of the data windows.

 Directly, by entering a time value in the Cursor field and clicking the Set button.

When the Time Axis display is set to Elapsed Time, the cursor position may be entered:

 In seconds, e.g., 135

 In hours:minutes:seconds, e.g., 2:15 or 0:2:15

 In days, hours, minutes, seconds, e.g., 3d 4h 2m 15s

If the first character of the time specification is a plus (+) or minus (–) sign, the time is taken
relative to the current cursor position.

When the Time Axis display is set to Time of Day, times are taken as time-of-day; day
specifications are relative to 0, the first day of the test. Thus, 1:00 PM on the day following the
start of the test would be entered as 1d 13:00:00.

The Live Update check box causes the data display to track new data as a test is running. When
it is set, the cursor is automatically positioned on the most recently acquired sample and the
windows scroll accordingly. Moving the cursor automatically turns off this feature.

When the Zoom Out/In slider is set to a resolution other than the finest, the display may be
automatically zoomed by clicking the mouse at one edge of the area of interest, holding down
the left button, and dragging it to the other edge. The zoom setting and scroll position will adjust
to show the selected area at the highest resolution possible.

The Test window shows the test start time and date, elapsed time, and test state.

The Data at Cursor window shows the cursor position (elapsed time or time-of-day, as
selected), the count of the selected parameter at the cursor, and the maximum value for that
parameter at the current display resolution.

The Search controls allow searching, forward or backward, for an occurrence of the specified
parameter. The search starts from the cursor location; it will not wrap beyond the end (forward)
or beginning (backward) of the data. For the B1, B2, FAS, MS-REI (REI-L), B3, REI-P, and
TSE parameters, one may specify a search threshold: the search will find only intervals
containing at least that many errors.
