1000BASE-XD CWDM SFP specifications
The part numbers of the 40 km models range from AA1419025-E5 to
AA1419032-E5.
CAUTION
Risk of equipment damage
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.
