1000BASE DDI CWDM 40 km SFP specifications
The 1000BASE SFPs provides CWDM gigabit Ethernet connectivity using single mode fiber.
These SFPs support full-duplex operation only.
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.
The following table describes specifications for 1000BASE DDI CWDM SFPs numbered
AA1419053-E6 to AA1419060-E6.
Caution:
Risk of equipment damage
To prevent damage to the optical receiver, ensure that at least 4 dB of attenuation exists
between the transmit and receive ports.
