OP940-SW Multichannel Insertion Loss & Return Loss Meter

Accurately test your multiple simplex, or multi-channel cable assemblies faster, easier and more efficiently with the OP940 Switched Optical Return Loss and Insertion Loss Meter.

The multichannel OP940 is an internally switched Insertion Loss (IL) and Return Loss (RL) meter designed for testing ribbon cables and multi-pin termini. Used worldwide by some of the largest companies, this system offers the fastest and most accurate multichannel IL and RL testing experience in the industry.

FEATURES & BENEFITS

—
Simplified Test Setup

The OP940 measures quickly and accurately without the need for mandrel wrapping or the use of index matching gel.

Fastest IL/RL Measurement

A single channel, dual wavelength, IL and RL test with the multichannel OP940 takes less than 4 seconds.

Most Accurate RL Measurement

By making use of a wide dynamic range (-10dB to -80dB) for RL measurements, the multichannel OP940 is able to adjust for attenuation in the reference setup, which results in the most accurate Return Loss results in the industry.

Easy Maintenance For Minimal Downtime

To minimize downtime on high volume production lines due to optical end-face damage, the removable front panel gives you access to the source connector, allowing you to re-polish the connector if it gets damaged.

Customizable

The multichannel OP940 can be built in numerous channel counts from 4 to 24. The system is available with Single Mode, Multimode, and FTTX wavelengths and a variety of core sizes and detector options.
