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.
◆ Providing a standard STM-1 electrical interface complying with G.664;
◆ Providing a standard STM-1 optical interface complying with G.664;
◆ Providing two top-mounted alarm output interfaces in the programmable relay mode, and two switch input interfaces;
◆ With excellent synchronization characteristics;
◆ Optional power supply, DC-48V or AC220V.
