The OP725 is an optical switch for single mode or multimode applications available in a slim-line, half-rack enclosure. This optical switch is USB powered and incorporates the latest technology in high-speed switching. With high repeatability and low loss, the OP725 is ideally suited for bidirectional testing.

Paired with our OP940 Insertion & Return Loss Meter, operators can make quick work of measuring both ends of cables in a truly bidirectional manner.

The OP725 can be connected to the OP940 via USB to allow control of bidirectional switching via the OP940’s front panel controls or in OPL-PRO software.

It can also be used in more complex, multi-instrument configurations with other OptoTest instruments

(for example, an OP710) and OPL-MAX / OPL-LOG software.
