1000BASE-XD CWDM SFP specifications
The 1000BASE-XD SFPs provides CWDM gigabit Ethernet connectivity using single mode
fiber. These SFPs support full-duplex operation only. The part numbers of the 40 km models
range from AA1419025-E5 to AA1419032-E5.
Important:
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.
