Camarillo, California-based company OptoTest has launched the OP940-OP725 bidirectional insertion and return loss (IL/RL) test system, which allows operators to make quick work of measuring both ends of cables and duplex connectors.

The system includes an updated version of the OP940 insertion and return loss meter, which can provide direct control of the new OP725 optical switch via USB link.

California-based test and measurement supplier OptoTest has introduced the OP-SPHR integrating sphere, which is designed as a cost-effective method for testing optical fibres terminated with high-density connectors such as MXC, MTP/MPO, or bare fibre.

The integrating sphere works by reflecting and evenly distributing the light over the entire surface of the internal cavity, making Insertion Loss (IL) measurements stable and repeatable with low polarisation dependence.
