The Viavi JDSU 4126 MA is a singlemode OTDR module with dual-wavelength operation at 1310/1550 nm, offering an impressive 40/38 dB dynamic range. It is optimised for FTTH, metro, and access network qualification, supporting testing through up to 1x32 splitters on short to medium-haul fibre spans. The APC SC connector and 0.9 m event dead zone make it highly capable for modern FTTx deployment and verification.
Specifications at a glance:
• Wavelengths: 1310 / 1550 nm

• Connector: APC SC
• Event Dead Zone: 0.9 m
• Attenuation Dead Zone: 4 m
• Range: up to 260 km
• Network Type: FTTH / Access / Metro
• Applications: Short/medium-haul qualification, FTTH test up to 1x32 splitter
Included in the sale:
• Viavi JDSU 4126 MA SM OTDR module
Please note that we have multiple units in stock, and the images presented are of one of them, therefore the cosmetic condition of the exact item you will receive may slightly differ.
The Viavi (formerly JDSU) 4126 MA is a metro access singlemode OTDR module designed for use with compatible Viavi MTS/T-BERD modular test platforms. It delivers higher dynamic range than last-mile variants, making it well suited to FTTH qualification, access network characterisation, and metro fibre testing across extended distances.
The 4126 MA integrates a dual-wavelength source at 1310 and 1550 nm with a 40/38 dB dynamic range, enabling reliable testing through passive splitter networks of up to 1x32 — ideal for PON infrastructure qualification. Its extremely short 0.9 m event dead zone allows precise fault location even in dense fibre environments.
Key Features:
• 40/38 dB dynamic range at 1310/1550 nm for extended reach testing
• 0.9 m event dead zone for high-resolution near-end fault detection
• 4 m attenuation dead zone for accurate splice and connector loss measurement
• Supports FTTH, metro, and access network topologies
• Range up to 260 km
• APC SC connector interface
• Suitable for short to medium-haul fibre qualification through up to 1x32 splitters
• Field-replaceable module compatible with Viavi MTS/T-BERD platforms
