Datasheet

Overview

The VIAVI MAP Series Optical Spectrum Analyzer (mOSA-C1) is a diffraction grating-based spectral measurement module that occupies a single slot in a MAP-300 mainframe. It is based on a monochromator design and operates over the full single-mode fiber range of 1260 to 1660 nm. A C- and L-band version covering 1500 to 1655 nm is also available.

The module combines a 20 pm resolution bandwidth with sampling at 1 pm resolution, so complete traces can be captured at full resolution and then zoomed and panned to find regions of interest. A full-span measurement takes 1.6 s, which makes the module suitable for both laboratory and production-line use. Scans over smaller ranges can be used to shorten measurement time.

Calibration

An internal calibration source with an acetylene gas cell and a broadband light source is built into the module. The user connects it to the input with a manual connection on the faceplate, and the calibration process then runs automatically in a few minutes.

Software and automation

The graphical user interface is accessed through a web browser, an HDMI monitor or an optional integrated touchscreen. It provides markers, trace memory, trace math and automated referencing. Optional licensed analysis packs add passive component, transceiver, amplifier and CW source measurements. For remote automation, SCPI commands run over Ethernet, with GPIB available as an optional port. Two automation methods are provided: a Direct-to-Module command set for trace acquisition, and an Application Environment interface with advanced analysis functions.

Platform

The mOSA-C1 belongs to the MAP LightDirect family of modules and is compatible with the MAP-300 mainframe family. It can be combined with other MAP optical application modules for testing coherent and client transceivers, source lasers, optical amplifiers and passive components.
