DESCRIPTION:

The VIAVI E4136B-PC 4100 Module B OTDR is a professional optical time domain reflectometer module engineered for fibre installation, qualification, troubleshooting, and maintenance workflows across telecom, datacentre, enterprise, metro, long-haul, and FTTx/PON environments. Designed for use with VIAVI OneAdvisor 800, T-BERD/MTS-2000 V2, T-BERD/MTS-4000 V2, and MTS-5800 platforms, the module delivers advanced OTDR analysis capability within a portable modular field-testing ecosystem.

The E4136B-PC configuration supports singlemode OTDR testing at 1310 nm, 1550 nm, and 1625 nm wavelengths, enabling fibre construction testing, preventative maintenance, and live network troubleshooting from a single module. The 1625 nm wavelength supports in-service troubleshooting capability without interrupting active traffic in supported optical network environments.

Built on the 4100 Series Module B architecture, the platform provides higher dynamic range capability suitable for metro, long-haul, wireless x-haul, and passive optical network testing applications. The module supports Smart Link Mapper graphical fibre analysis, automated OTDR workflows, multiple trace display modes, Test Process Automation integration, and consolidated reporting functionality for streamlined field operation.

The E4136B-PC uses PC optical connector configuration with compatibility for interchangeable SC, LC, and FC connector adapters depending on installed adapter type. The module is designed for fibre acceptance testing, network commissioning, troubleshooting, maintenance, and certification workflows across modern optical infrastructure deployments.
