COM Port Pinout Assignments
Matrix DFE-Platinum Series Module Installation Guide A-3
provides the input/output specifications for each XFP version as specified in the IEEE
802.3ae‐2002 standard.
The following XFP specifications in
meet or exceed the IEEE 802.3ae‐2002 standard.
COM Port Pinout Assignments
The COM port is a serial communications port for local access to Local Management. Refer to
for the COM port pin assignments.

1. The limiting factor is saturation of the receiver by the transmitter. When presented with a signal at a strength
above the saturation point, the receiver cannot distinguish between pulses, though no hardware damage
occurs.
