WWDM Application
WWDM (widely spaced wavelength division multiplexer) models multiplex and demultiplex
wavelengths in the 1310nm, 1480nm, and 1550nm windows, and are protocol, speed, and line
code transparent. Each 6002/3/4 model is unidirectional (meaning that light travels in only one
direction on a fiber line) and transmits signals through a composite pair of single mode fibers.
Customer devices transmit (Tx) and receive (Rx) channel-to-channel signals through the local
WWDM. Optical signals are received and demultiplexed with isolation levels that minimize
channel crosstalk.
Note: The 6002/3/4 rack mount models used in a chassis configuration contain EEPROM's for
identification and management purposes. The stand alone models are non-powered units, which
have no user configurable switches and require no special jumpers.
For the correct fiber optic cable application see the WWDM Installation Diagram in Figure 4.
Note: All optical connections must be cabled using the Tx to Rx and Rx to Tx scheme.
Important: Do not over tighten FC/PC connectors or damage may occur.
