1000BASE-EX DDI SFP specifications
The following table describes the 1000BASE-EX DDI SFP. This SFP
operates at 1550 nm and has a reach of up to 120 km. The part number of
this SFP is AA1419071-E6.
CAUTION
Risk of equipment damage
To prevent damage to the optical receiver, ensure that at least 14
dB of attenuation is present between the transmit and receive
ports.
To attain the BER of 10
-12
, the minimum attenuation between the
transmit and receive ports is 15 dB.
