Viavi E8136D OTDR Module

Overview

The Viavi E8136D is part of the 8100-Series OTDR EVO family and is designed for comprehensive fiber testing and commissioning. It features single-mode support at 1310, 1550, and 1625 nm wavelengths with exceptional performance specifications including up to 50 dB dynamic range and industry-leading dead zone performance. The module integrates OTDR, continuous wave light source, and power meter functionality in a single-port tool for maximum flexibility in field applications.

Key Features

• Dynamic range of 50/50/50/48 dB across all wavelengths (1310/1550/1625/1650 nm)
• Event dead zone of 0.5 m for full element event characterization on fiber links 2 m apart
• Integrated continuous wave light source with 0 dBm output power
• Integrated power meter with ±0.5 dB accuracy at –30 dBm
• Pulse width from 2 ns to 20 µs for flexible testing parameters
• PON-optimized to test through 1x128 splitters with 15 m attenuation dead zone
• Automatic traffic detection to avoid signal interference during OTDR testing

Applications

• Fiber network commissioning and acceptance testing
• Network upgrades and capacity expansion verification
