5.6 Fiber Optic Transceiver Module (AE04A-D1100-009)
5.6.1 Description
The Fiber Optic Transceiver Module converts the Downlink and Uplink electrical
(RF) signals into optical signals prior to routing the signals between remote BDAs
and the base transceiver station. The fiber optic transceiver is capable of
providing up to 18 dB of RF gain. So for fiber optic links with 9 dB or less of
optical loss, the fiber transceiver can negate that loss and in turn provide a fiber
link that is lossless. During the BDA setup, the fiber optic link is set to 0 dB.
The fiber optic transceiver module has an on board RISC processor that provides
optional alarming/status monitoring and communications capability. The fiber
transceiver is also equipped with high reliable parts to provide a long trouble-free
operating life. Should the module be suspect of failure, the entire module should
be replaced. Note, due to the possibility of laser radiation hazard, the fiber optic
transceiver module cover should never be removed to troubleshoot or to adjust the
laser optical power.
