This configuration may be used for a point-to-point connection or for a Linear
Add/Drop topology where all links originate from a node at one end of the
chain.
•
Configuration 2
: Two EXP ports
When two OADMs are used, both EXP ports of the PL-300 are available and
should be connected to each other.
This configuration should be used in a Ring topology or in a linear add/drop
topology where new links may be added by nodes along the chain.
The following table provides information regarding the fiber and connector
specifications for the EXP port.

DCM Ports
The DCM ports exist only for PL-300 DCM models. The DCM provides chromatic
dispersion compensation for DWDM networks. The DCM port is attached to the
fiber that arrives from the network before connecting it to the local amplifier.
The DCM module is unidirectional, therefore, each port handles one direction. The
DCM port has In and Out connectors. The In connector should be attached to the
incoming signal, while the Out connector transmits the same signal after disparity
compensation.
The following table provides information regarding the fiber and connector
specifications for the DCM port.

MNG Ports
There may be up to two OSC (Optical Supervisory Channel) ports. The front panel
has a single port labeled "MNG" or two ports labeled "MNG1" and "MNG2". These
ports are used the MUX/DEMUX remote management channel.
