Product Overview

Introduction

The ML7008F-LFT is a fully-featured BERT that can be configured as 16 transmitters and 8 receivers of 224G, 116G and 56G PAM4 and 106.25G NRZ and their derivative dynamic rates.

The ML7008F-LFT is compliant with the IEEE P802.3dj, and OIF CEI 112G LR.

The transmitters support all standard test patterns mandated by the specs such as PRBS13Q, PRBS31Q, etc. while the advanced transmitters support SSPRQ.

The ML7008F-LFT supports transmitter and receiver equalization up to 40dB to overcome signal integrity impairments due to channel losses or reflections.

The ML7008F-LFT is available as a standalone instrument or as a module in the MultiWave Test Platform (MWTP), the MW7008F-LFT.

When fitted in the MWTP, two MW7008F-LFTs enable users to perform bi-directional traffic testing of transceivers from different vendors and of Active Copper Cables, Active Electrical Cables, and Direct Attach Copper.
