ATTENTION
For the 40 km CWDM SFPs, a minimum attenuation of 4 dB must be present
between the transmitter and receiver. To avoid receiver saturation, you must insert
a minimum attenuation of 4 dB when you test the CWDM SFP in loopback mode,
or use short runs of fiber with no intermediate CWDM OADM or CWDM OMUX.
To determine the expected signal loss for an optical add drop multiplexer (OADM),
an optical multiplexer (OMUX), or fiber length, see Nortel Ethernet Routing Switch
8600 Planning and Engineering—Network Design (NN46205-200).
For example, given a loss budget of 24 dB and assuming fiber loss of .25 dB/km,
up to 96 km reach is supported with no intermediate CWDM OADM or CWDM
OMUX.
