the Tx-1 to Tx-4 labels
respectively.


Generally, the insertion loss of each MPO connector is smaller than 0.35 dB, and
that of each LC connector is smaller than 0.15 dB.

The MPO connector is a high-precision connector with alignment function, so do
not insert and pull it at will or repeatedly; otherwise, the lifecycle of the fiber will be
shortened.
