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

single-mode fiber

cable is 3.0 dB (optical).

The maximum loss through the fiber can not exceed 3 dB (optical). T

he 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 be used throughout the

fiber network, including fiber distribution panels.
