Datasheet

Overview

The VIAVI OSA-110M is the standard model of the OSA-110 Series of compact optical spectrum analyzer (OSA) modules. It is housed inside the OneAdvisor 800 Fiber platform and is designed for field use, combining small size and low weight with full-band spectral measurement.

The module is suitable for coarse wavelength division multiplexing (CWDM) systems in the access network and dense wavelength division multiplexing (DWDM) systems in metro and core networks, down to 33 GHz channel spacing. It measures from 1250 to 1650 nm, and a built-in wavelength calibrator provides ±0.05 nm wavelength accuracy.

The combination of optical resolution and full-band measurement capability makes the OSA-110M suitable for testing power, wavelength, OSNR and drift during provisioning, maintenance and upgrades of WDM systems, including verification of high-speed 100/400/800G interfaces. Operation uses a graphical interface with automatic pass/fail analysis on the platform's color touchscreen.

The OSA-110M provides the standard feature set of the series; the in-band OSNR measurement technique for ROADM-based networks is provided by the OSA-110R model.
