Attenuation Requirements
Some shorter length cable runs will require attenuation to prevent over-
driving the receiver causing bit errors to occur on the fiber link. Use the fol-
lowing guidelines for adding attenuation:
• The Dual Transmitter requires no attenuation between fiber transmitter
and receiver connections at any cable lengths.
• All CWDM devices used in a point-to-point configuration with a cable
run from 0-20 km (12.4 miles), must be attenuated by 5 dB between
fiber transmitter and receiver connections.
• CWDM devices used with 8939FCA modules for a mux/demux config-
uration with a cable run from 0-12 km (7.5 miles), must be attenuated
by 3 dB between 8939CFA COM ports.
