Condition: Used — Very Good

This JDSU Viavi 41MPO12SM Multi-Fiber MPO-based OTDR Switch Module is in very good condition with minimal usage. Supplied as pictured, this is a module-only listing compatible with the MTS 4000 V1 and V2 platforms. The unit is suited for high-density fibre environments including data centres, FTTH/access networks, and Mobile Fronthaul (FTTA/C-RAN) applications. It automates OTDR testing across all 12 fibres of an MPO connector via the Cable-SLM software interface, eliminating the need for individual fanout patchcords.

Included in the sale:
• 41MPO12SM switch module only

The Viavi (formerly JDSU) 41MPO12SM is a Multi-Fiber MPO-based Switch Module designed for use with the MTS 4000 V1/V2 test platform. It provides an all-in-one integrated solution for automating OTDR testing of native MPO and high-fibre-count cables, replacing the need for multi-fibre fanout patchcords in native MPO link installations.

The module is particularly well suited for high-density fibre environments where multi-fibre MPO cables are used to eliminate the expense of running individual patch cords for each service turn-up. By combining an onboard MPO switch with OTDR capability, it enables fast and accurate testing of individual fibres within MPO cables.

Key Features:
Switch Ports: 12-port MPO-based automated switching
Software: Compatible with Cable-SLM application for automated test sequencing and pass/fail reporting
Module Compatibility: Works with all MTS 4100 series OTDR A, B, and FiberComplete B modules
Function: Automated "Test All Fibers" sequence delivering visual verdict per fibre
Fibre Management: Batch certify simplex fibres within high fibre count cables, starting at any fibre number
Fault Localisation: Precise detection of severe bends, high-loss splices, and dirty or poor connections

Applications:
Data Centre structured cabling, campus, and interconnect testing
FTTH fibre indexing and access network certification
Mobile Fronthaul (FTTA/C-RAN)
New installation certification up to industry standards
Fault troubleshooting in native MPO fibre links

The Cable-SLM software provides an intuitive interface giving an overview of a full test project with pass/fail status for each 12-fibre MPO connector tested, significantly reducing the time and complexity associated with high-fibre-count cable characterisation, certification, and troubleshooting.
