Datasheet

Overview

The VIAVI E8136D is the 1310/1550/1625 nm member of the 8100-Series OTDR EVO module family for the OneAdvisor 800 Fiber platform. The 8100D OTDR EVO modules are intended for the installation, turn-up and maintenance of single-mode standard and hollow core fiber in metro, long-haul and ultra-long-haul networks, as well as for fiber monitoring in and out of service and for submarine cable network certification and troubleshooting.

The module combines an OTDR, a broadband power meter and a continuous-wave light source on a single OTDR port. It offers up to 50 dB dynamic range with up to 256,000 acquisition points, a 0.5 m event dead zone and a 2.5 m attenuation dead zone, allowing closely spaced elements on a fiber link to be characterized. The module is PON-optimized to test through a 1x128 splitter.

Automatic traffic detection checks for live signals before an acquisition to avoid interference with, or damage to, an active optical transmitter. Smart Link Mapper (SLM) presents the measured link as an icon-based map to reduce OTDR interpretation errors without adding test time. Standard testing features include automatic macrobend detection, a summary results table with pass/fail analysis and FastReport onboard report generation.

Hollow core fiber

The 8100D modules also characterize hollow core fiber, with a dedicated dynamic range specification and a defined attenuation dead zone at the transition from solid core to hollow core fiber. VIAVI publishes a separate application note on testing hollow core fibers.
