STM-1 Optical to STM-1 Electrical Converter

Product Overview

AceCom offers  STM-1 Optical to STM-1 Electrical converter provides a simple and cost-effective conversion between STM-1 optical interface and STM-1 electrical interface. STM-1 Optical to STM-1 Electrical converter is an interface conversion equipment supplied with one STM-1 electrical (75 Ohms BNC) interface and one STM-1 optical (MSA compliant SFP) interface.

STM-1 Optical to STM-1 Electrical converter is a compact solution housed in a 1U high (44mm), 19-inch rack-mountable shelf, which can be installed in any DIN-standard 19-inch rack.

This unit offers five power supply options. Options for the power supply to the equipment include:

a) Dual DC - 48V Inputs (range -18V DC ~ -72V DC), for power input redundancy.
b) Single AC 110V AC to 240V AC, 50 / 60 Hz Inputs.
c) Single -48V DC (range -18V DC ~ -72V DC) Input.
