SmartClass OCC-55/-56 Optical Channel Checkers

Compact, low-cost test solution for installation, maintenance, and upgrades of CWDM & DWDM networks.

SmartClass OCC-55/-56 Optical Channel Checkers

VIAVI OCC-55 CWDM Optical Channel Checker and OCC-56 DWDM Optical Channel Checkers are compact and low-cost test alternative solutions to optical spectrum analyzers (OSA) for field service groups tasked with the installation, maintenance and upgrades of WDM systems testing. These selective power meters scan the WDM channels according to ITU-T wavelength grid and automatically record wavelength/frequency and related power level.


  • Low-cost alternative to an OSA for applications which do not require OSNR measurements.
  • Small and lightweight ruggedized design optimized for highly mobile field workers.
  • Save and download measurement results and certify your work with off-line report generation.


  • Installation, maintenance and upgrade of CWDM systems (OCC-55) and DWDM systems (OCC-56).
  • Analysis of single channel before MUX and DEMUX Qualification of multiplexed /signals.
  • In-service measurement and network element verification Channel drop testing at optical add/drop multiplexers (OADM).

Key Features:

  • ITU-T G.694.2 CWDM channels measurements (up to 18 channels) (OCC-55).
  • ITU-T 100/200 GHz DWDM channels (OCC-56).
  • Channel drift monitoring.
  • Bar Graph and Table of results display mode.
  • Light and compact (0.5kg/1.1lb).
  • Client USB port (standard) and Host USB port (optional).
  • Integrated fast battery charging function.
  • Report generation via OFS-355 Smart Optical Reporting Software.
