REMARKS
Two fibers per transport link
With 62.5 micron core MM fiber
With 50 micron core MM fiber
With 9 micron core SM fiber
Indoor installation only
Maximum composite output signal
requires maximum input signal
At room temperature
Over frequency, temperature, and
unit to unit. May have up to 2 dB
variation at upper band edge.
At max. composite output power
Will vary depending on access protocol
and number of carriers
Over frequency, temperature, and
unit to unit.
Prevents A/D saturation with large
inputs.
