Nortel Networks CWDM SFP manual

Page 32

Note: A minimum attenuation of 5 dB must be present between the transmitter and receiver. To avoid receiver saturation, you must insert a minimum attenuation of 5 dB when:

•testing the CWDM SFP GBIC in loopback mode

•using short runs of fiber with no intermediate CWDM OADM or CWDM OMUX

To determine the expected signal loss for a CWDM OADM, CWDM OMUX, or fiber length, see Installation and Networking Guidelines for Optical Routing, part number 212257-A.

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.
