Band Splitter Module
The Cisco Metro 1500 series system uses four channel groups consisting of eight
channels of data communication. The band splitter module (BSM) combines and
splits these groups of multiplexed optical channels. The group signals from the
MUX modules are combined and routed to the input ports and then are
multiplexed for data transmission through one fiber to the BSM at the remote side
of the link. Simultaneously, the BSM receives the combined signal at its remote
input from the remote side of the link. This mixed signal is split into four groups
for demultiplexing in the DMX modules.
