2-port 40GBASE QSFP+ test module

M2QSFP+

The M2QSFP+ is a wire-speed 2-port 40 / 10 G test module using QSFP+ form-factor.

2-port 40GBASE QSFP+ test module

The M2QSFP+ is a 2-port 40GBASE Quad Small Form-Factor Pluggable Plus (QSFP+) test module for our XenaCompact and XenaBay chassis.

This dual-speed test module provides 2 x 40G or 8 x 10G test ports via a simple software configuration and is compatible with 40G QSFP+ compliant transceiver modules, using MPO connectors.

It delivers a breakthrough price/performance benchmark for PRBS, load-stress, and functional testing of Ethernet equipment and network infrastructure.

Two real-time histograms per port. Each histogram can measure one of RX/TX packet length, IFG, jitter, or latency distribution for all traffic, a specific stream, or a filter.
Loopback modes- L1RX2TX – RX-to-TX, transmit byte-by-byte copy of the incoming packet
