Datasheet

Overview

The VIAVI OSA-110R is a compact full-band optical spectrum analyzer (OSA) module of the OSA-110 Series, housed inside the OneAdvisor 800 Fiber platform for field use. It covers the 1250 to 1650 nm range and is suitable for CWDM and DWDM networks down to 33 GHz channel spacing.

In addition to the standard features of the OSA-110M, the OSA-110R includes the VIAVI in-band measurement technique, which measures the true OSNR in ROADM-based networks and high-speed transmission systems where tight channel spacing prevents conventional out-of-band OSNR measurement.

The combination of optical resolution and full-band measurement capability makes the module suited to testing power, wavelength, OSNR and drift during provisioning, maintenance and upgrades of WDM systems. A built-in wavelength calibrator provides the specified wavelength accuracy, and the graphical interface offers automatic pass/fail analysis on the platform's color touchscreen.
