Connecting an OMUX 43
3 Connect the fiber optic cables from the GBIC or SFP transmit (Tx)
and receive (Rx) connectors to the OADM Equipment RX and TX
Equiment connectors.
4 Connect the west network backbone fiber optic cable to the OADM
west connector.
5 Connect the east backbone fiber optic cable to the OADM east
connector.

Procedure job aid: Optical add/drop multiplexers
The Nortel passive CWDM Optical Add/Drop Multiplexer (OADM) sends
and receives signals to and from CWDM GBICs and SFPs installed in
the switch. It adds or drops a specific wavelength from the optical fiber,
and allows all other wavelengths to pass through unaffected. The OADM
supports tow separate fiber pathways traveling in opposite directions (east
and west) so that the network remains viable even if the fiber is broken at
one point on the ring.
Connecting an OMUX
Use this procedure to connect the OMUX to SFP or GBICs and to eash and
west backbone interfaces.
WARNING
Multiplexing together several GICs or SFPs can produce a radiant
power level in the fiber that exceeds the class 1 laser limit. To
avoid damage to yourself or to the equipment, take care that you
follow proper connector safety and cleaning procedures.
Step Action
1 Insert the GBICs or SFPs into their respective modules.
2 Clean all fiber optic connectors.
3 Connect the fiber optica cables from the GBIC/SFP TX and RX to
the OMUX Equipment RX and TX Equipment connectors. The GBIC
or SFP wavelength must match the OMUX equipment connector
wavelength. The TX of one device must always connect to the RX
of the next device.
4 Connect the network backbone east fiber optic cables to the east
(left) OMUX.
