Overview
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

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
