Datasheet

Overview

The VIAVI OSA-4100 is an optical spectrum analyzer module in the Nano OSA 4100 Series. It is designed for the deployment, maintenance and troubleshooting of passive and active CWDM and DWDM fiber networks, and covers the full wavelength band from 1260 nm to 1650 nm with high-resolution measurement.

The module scans an optical CWDM or DWDM system over the full wavelength range and records all channels with their ITU-T channel number, wavelength or frequency, offset and power level. In addition to these channel verification functions, the OSA-4100 measures the optical signal-to-noise ratio (OSNR) per channel to qualify amplified links. Out-of-service in-band OSNR measurement and the drift test application for channel power and wavelength are included with the OSA-4100.

An integrated SFP/SFP+ slot can drive fixed or tunable pluggable transceivers, allowing technicians to validate or program transceivers in the field. The SFP functions require the SFP software option.

The module operates on the T-BERD/MTS-2000 V2, T-BERD/MTS-4000 V2, T-BERD/MTS-5800, CellAdvisor 5G, OneAdvisor 800 and OneAdvisor 1000 platforms, where optical spectrum analysis can be combined with Ethernet/BERT, OTDR or wireless RF test. The user interface supports multi-touch gestures and automated tests.
