STM-1 Optical to STM-1 Electrical converter provides
a simple and cost-effective conversion between STM-1
optical interface to STM-1 electrical interface.
STM-1 Optical to STM-1 Electrical converter is an interface
conversion equipment supplied with one STM-1 electrical
interface and one STM-1 optical interface.
STM-1
Optical to STM-1 Electrical converter is a compact
solution housed in a 19" rack 1U high, which can be
placed on the desktop or installed in a standard 19 inch
rack.
This unit
offers three power supply options. Options for the power
supply to the equipment include:
- AC~220V
- DC - 48V
- AC~220V with DC - 48V
backup.
STM-1
Optical to STM-1 Electrical converters converter
complies with ITU-T and the relevant SDH specifications.
The rear
panel includes power socket and alarm output terminal
interface.
