Low-cost 2-port 1 Gigabit Ethernet test module

Advanced timing test module for Synchronous Ethernet test apps.

The M2SFPT is a low-cost 2-port 1 Gigabit Ethernet test module for Layers 2-3.

Based on Xena’s advanced architecture, the M2SFPT is an advanced timing test module developed for Synchronous Ethernet test applications.

It is available for both the 4U 12-slot XenaBay chassis and the robust, transportable 1U XenaCompact chassis.

The M2SFPT comes with XenaManager-2G – an easy-to-use application for handling both routine and advanced test schedules that includes XenaScripting, Xena2544, Xena1564, Xena3918 and Xena2889.
