OS414’s front panel has 4 port blocks each with 5 LC duplex connectors numbered
left to right and top to bottom from 1 to 4. Each port block is an individual duplex
1x4 optical switch, consists of 1 input port labeled as “IN” and 4 output ports
labeled as “O1”, “O2”, “O3” and “O4”.
Even though we refer ports as input and
output ports they are bi-directional (duplex) so you can use them as either input or
output. This means switch can act as 1x4 or 4x1 switch
.
Eac
h input ports’ Tx and Rx are
internally
connected
to
corresponding output ports’ Tx
and Rx. OS414 uses 8 such 1x4
switches, as one shown on right, to
provide 20 ports connectivity.
