Overview
TM2-SFPXC
The TM2-SFPXC is a single slot module incorporating two fast switchover protection protocol with two options of
independent transponders. Each of the four port can be fitted operation:
with an SFP transceiver from any standard type – MM, SM,
CWDM, DWDM or copper. The main differences between this 1. Protection between two transponders in a single module.

minimal space and power consumption.
The TM2-SFPXC supports various data rates of up to 4.25 Gbps.

The Link Integrity Notification (LIN) function allows the terminal
equipment to detect a link failure in the path between the two
end-nodes, regardless of the location of the failure.
