Note: In this configuration (8959FCA to 8939FCA utilizing CWDM transmitters), if the distance between 8939FCA modules is l
ess than 12 km (7.5 m),
a 3 dB attenuator must be installed somewhere between the COM ports on the 8939FCA modules to prevent overdriving the receiver
causing bit errors
to occur on the link.

Distance of up to 50km
( see note
for inline

requirements)
