NOTICE
Canoga Perkins has prepared this users manual for use by customers and Canoga Perkins personnel as
a guide for the proper installation, operation and/or maintenance of Canoga Perkins equipment. The
drawings, specifications and information contained in this document are the property of Canoga

However, no guarantee is given or implied that the document is error free or that is accurate with
regard to any specification.
The 6703 Coarse Wavelength Division Multiplexer (CWDM) Transponder converts optical signals
from standard optical interfaces to Single mode CWDM wavelengths for use with a CWDM
Multiplexer/Demultiplexer (Mux/Demux). The 6703 is protocol transparent and uses Avalanche
Photo Diodes and Clock Data Recovery (CDR) to increase receiver sensitivity at high data rates.
The 6703 supports these options:
• Industry-standard and proprietary data rates from 100 Mbps to 2.5 Gbps
• Small Form Pluggable (SFP) transceivers, optional for Local port and standard for Remote port;
order compatible, supported SFPs from Canoga Perkins
• Local and Remote optical port loopback
• Variable clock for data recovery; supports eight user-defined rates
• SpeedCop for monitoring received transmission rates
Connect the remote optical interfaces from five 6703 CWDM Transponders to one 6004 CWDM
Passive Optical Mux/Demux to carry five full-duplex optical channels on one fiber pair. Similarly,
connect nine 6703 Transponders to one 6008 CWDM Passive Optical Mux/Demux to carry nine
channels on a fiber pair.
You can use the 6703 for these general applications; Figure 1:
• Wavelength Converter (transponder), which receives an optical signal at 850 or 1310 nm and
converts it to a specific CWDM wavelength or standard 1310 nm high-power optics
• SpeedCop function, which monitors and assigns data rate limitations on the link
• 3R Repeater, which reshapes, retimes, and retransmits the optical signal
Figure 1. 6703 Wavelength Converter Function
You can use either of these methods to manage the 6703 through software:
• CanogaView® Network Management System (NMS), a management package with graphical user
interface (GUI) that requires a network connection and can be opened through a web browser
from a network terminal or through the internet
• VT100 Terminal Emulation through a Telnet session, HyperTerminal or similar terminal
emulation software

The 6703 front panel, shown in Figure 2, includes:
• Status LED
• Reset button
• TRM/MDM switch: Selects terminal emulation or a dial-up modem
• EIA-232 (Console) port with RJ-48 connector: Provides software management access
• Local port with Rx/Tx LEDs: Receives from/transmits to the local equipment; LEDs show port
status; optical interface can be fixed SC at 1310 nm (6703-0003) or SFP (6703-0000)
• Remote port with Rx/Tx LEDs: Receives from/transmits to the 6004 or 6008 Passive
Mux/Demux or remote site; LEDs show the transmitter and receiver status for the port; optical
interface is always an SFP
• LCDR/SC and RCDR/SC LEDs: Show CDR and SpeedCop status for local and remote ports

Hardware Installation and Operation
This section describes how to install a 6703 in a UCS 1000 or 1001 chassis or in a Model 1040 or
1050 standalone enclosure.
2.1 Install the Module
You can install the 6703 module in any slot from slot 1 to 15 in the UCS 1000, in either slot in a
UCS 1001, or in a Model 1040 or 1050 standalone enclosure. To install the module, follow these
steps:
1. Unpack and inspect all components. Save the shipping carton and packing materials in case you
need to return any equipment; see Appendix A for information about returning equipment.
2. Insert the module in the selected slot, pushing it firmly into the backplane connector. Do not
force it.
3. Hand-tighten the captive screws to secure the module in the chassis.
Note: The 6703 module is hot-swappable and can be inserted or removed at any time without
affecting other modules.
4. Plug the SFP(s) into the port(s); the slot is keyed. To remove an SFP, either lift the bail or press
the button on the SFP, then gently pull it out.
Dirty optical connectors are a common cause of link loss or attenuation problems, especially for
single mode fiber (SMF). Clean the connectors before plugging in a cable and whenever there is a
significant or unexplained light loss. To prevent contamination, always install protective dust covers
on unused fiber optic connectors.
5. Wipe the ferrule and the end-face surface of the male fiber coupler with a lint-free, isopropyl
alcohol pad from a fiber cleaning kit.
6. Use canned air to blow any dust out of the female fiber coupler.
Caution: To avoid damaging the fiber end-surface or connector, use extreme care when
installing or removing cables.
7. Plug in the optical cables with Local to Local and Remote to Remote orientation. The remote
device can be either a CWDM Mux/Demux or a remotely located 6703. See Figures 1 and 2.
• For an SFP, push the cable in until it clicks. To unplug the cable, push the button on the side
of the cable and gently pull.
• If you have a duplex connector, use Tx to Rx, and Rx to Tx orientation.

8. If you will directly manage the 6703, such as in a UCS 1001 or 1050 standalone enclosure, follow
these steps:
a. Plug the RJ-48 serial cable into the console port on the front of the 6703.
b. Plug the other end of the serial cable into an RJ-48 to DE-9 adapter, then into the modem or
the COM port on the PC.
c. Set the TRM/MDM switch to TRM for local management through a local terminal or to
MDM for remote management through a dial-up modem.
9. For ease of maintenance, label each cable and connector with the signal name and direction.
2.2 Front Panel LEDs
The front panel includes LEDs that show general status for the 6703 and specific status for each Rx
and Tx port. See Table 1.
