directly from the Internet. Go to the www.nortelnetworks.com/
documentation URL. Find the product for which you need
documentation. Then locate the specific category and model or

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 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.
