The compact multichannel OP940 is an internally switched Insertion Loss (IL) and Return Loss (RL) meter designed for MPO/MTP® testing. With a design that reduces setup time, cost, risk, and footprint, the OP940-CSW is the evolution of the MPO/MTP® testing experience that is used worldwide by industry leaders. The fastest and most accurate IL and RL test system in the industry is better than ever.



Simplified Test Setup

The compact multichannel OP940 measures quickly and accurately without the use of mandrels or index matching gel.

Fastest IL/RL Measurement

A 12 channel, dual wavelength, IL and RL test with the compact multichannel OP940 takes less than 40 seconds.

MPO/MTP® Interface

The compact design of the OP940-CSW significantly reduces time and cost. With an MPO/MTP® front panel interface, there is no need to use expensive fanout cables that over-complicate the cable setup. The reference and measurement processes are faster, more efficient, and less prone to error than ever before.

Most Accurate RL Measurement

The compact size of the OP940-CSW was achieved without compromising quality or accuracy. By making use of a wide dynamic range (SM, FTTX: -10dB to -80dB) for RL measurements, the OP940-CSW is able to adjust for attenuation in the reference setup, which results in the most accurate RL results in the industry.
