6.7 Optical Power Budget
Fusion Wideband uses SC/APC connectors. The connector losses associated with
mating to these connectors is accounted for in the design and should not be included
as elements of the optical power budget. The reason is that when the optical power
budget is defined, measurements are taken with these connectors in place.
The Fusion Wideband optical power budget for both multi-mode and sin-
gle-mode fiber cable is 3.0 dB (optical).
The maximum loss through the fiber can not exceed 3 dB (optical). The maximum
lengths of the fiber cable should not exceed 500m
(1,640 ft) for multi-mode and 6 km
(19,685 ft) for single-mode. Both the optical budget and the maximum cable length
must be taken into consideration when designing the system.
NOTE: It is critical to system performance that only SC/APC fiber connectors are
used throughout the fiber network, including fiber distribution panels.
