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.
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.
