Overview

The VIAVI 8100-Series OTDR EVO family consists of 8100D OTDR modules for the OneAdvisor 800 Fiber platform. The modules test single-mode standard and hollow core fibers in access, metro, long-haul and ultra-long-haul networks, for commissioning, network upgrades and troubleshooting.

The modules come in single-, dual- and tri-wavelength versions covering 1310, 1550, 1625 and 1650 nm, with up to 50 dB dynamic range and up to 256,000 data points. On versions with the option, a CW light source and a broadband power meter for the single-mode wavelengths are built into the OTDR port, so one port serves as OTDR, power meter and light source.

Traffic detection checks the fiber for live signals before an OTDR test starts, so the test does not interfere with traffic or damage optical transmitters. Smart Link Mapper (SLM) presents the trace as a link map to cut interpretation errors without adding test time. Standard features include automatic macrobend detection, a summary results table with pass/fail analysis, and onboard report generation with FastReport.

The modules are also optimized for PON testing through splitters up to 1x128. A hollow core fiber mode characterizes solid-core to hollow-core transitions for high-speed networks and data center interconnects.
