Optical Protection Switch Module - for OCMR

About the Product

The optical protection switch OPSAB can be used for laser protection or for fibre-line protection. The OPSAB maintains optical output in the event of failure of an optical input. The unit includes an electrically-operated optical switch. The switch can be activated both manually and automatically.

The OPSAB, in normal operation mode, allows the output from input A to be switched to a common output. In the event of a laser failure or optical line failure the OPSAB switches to input B.

The OPSAB is available in two distinct versions. The basic version operates on external voltage reference levels as provided by our range of LTM13 and LTM15 DFB laser transmitters. There is an option for integrated optical sensing on the input ports.

Automatic switching has three modes of operation: peer-to-peer for equal priority between inputs, master A for priority to input A, or master B for priority to input B.

Both versions offer a manual override setting, which is accessed via our OCM management system.
