Optical STM-1 to Electrical STM-1 converter

STM-1 photoelectric converter provides coverting function between electrical interface and optical interface for STM-1 service based on SDH technology.

STM-1 photoelectric converter is an interface conversion equipment supplied with one STM-1 electrical interface and one STM-1 optical interface. All the interface daughter boards support hot swap.

It carries the data services via the container in SDH.

STM-1 photoelectric converter applies 19″ rack of 1U high, which can be placed on the desktop or installed in a cabinet of 2.2m or 2.6m high, and can directly drive the top-mounted aural-visual alarm unit.

There are three options for the power supply to the equipment: AC ~220V, DC -48V, and AC ~220V with DC-48V backup. The choise is to be made by the user according to the actual situation.
