Optical Power Budget

6.7 Optical Power Budget
Fusion 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 ele-
ments 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 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). The maximum
lengths of the fiber cable should not exceed 500m for multi-mode and 6 km
(1,640 ft)
for single-mode. Both the optical budget and the maximum cable length
(19,685 ft)
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.
