Passive Loopback Lineup

Part Number Form Factor Description

ML4062-LB-112 QSFP-DD Type 1 8x112GEL loopback with 16 W programmable power dissipation, optimized SI and MSA-compliant EEProm

ML4062-LB2a-112 QSFP-DD Type 2A 8x112GEL loopback with 30 W programmable power dissipation, optimized SI and MSA-compliant EEProm

ML4064-LB-112 OSFP 8x112GEL loopback with 17.5 W/24 W/30 W programmable power dissipation, optimized SI and MSA-compliant EEProm

Passive loopback test coverage of 8x112GEL is limited due to added insertion loss

Active loopbacks are necessary to realize full test coverage of 8x112GEL ports19

CMIS Test Suite

Validate host/module implementation of Common Management Interface Specification

Certify that parameters like optic DOM and ID, errors and alarms are monitored correctly on host

Pass/Fail state machine test - see top right

Monitor and save I2C transactions between host and pluggable

Force host alarms (high/low/tri-state)

Enable versatile CMIS testing in three modes:

1) Master mode: Analyzer behaves as a host for a module DUT

2) Slave mode: Analyzer behaves as a module for a Switch DUT

3) Bypass/Sniffer mode: Analyzer reports on communication between module and switch
