Fiber Optics Powerwave
4 - 14 Rev. P1A9-Draft 2004-11 VM100 56/EN – User’s Manual
The optical power loss for an optical 30/70 percent splitter is 5.2dB/1.5dB, for a 50/50
percent splitter 3dB. The power loss for an optical WDM is 1dB. Additional connectors
add the loss by 0.5dB each. Due to the power sharing, up to approximately four slave
nodes (FOR) can be connected to a master FON unit (BMU). For additional slave nodes,
another FON unit has to be inserted in the BMU.
The optical WDMs and splitters are usually included in the FOU located in the BMU.
Figure 4-13 shows, schematically, these parts outside the BMU cabinet.
