Description
Basic
function
Adds or drops four consecutive wavelengths to or
from multiplexed signals.
Provides a cascading optical port to cascade with
another optical add/drop multiplexer (OADM) board.
The optical multiplexing output port supports
detection of optical power sent to the PIN diode.
Supports automatic optical power commissioning
