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.
1000BASE-ZX CWDM SFP specifications
The 1000Base-Zx SFPs provide CWDM Gigabit Ethener connectivity using
single-mode fiber (SMF). These SFPs support full duplex operation only.
The part numbers of the 70 km models range from AA1419033-E5 to
AA1419040-E5.
ATTENTION
For the 70 km CWDM SFPs, a minimum attenuation of 10 dB must be present
between the transmitter and receiver.
ATTENTION
AA1419033-E5 to AA1419040-E5 continue to be supported. However, they are no
longer orderable. Order AA1419061-E6 to AA1419068-E6 as their replacements.
