STM-1 Optical Repeater

Product Overview

Aries Telecom offers VCL-STM-1 Optical Repeater is a cost-effective solution which allows its users to transport an optical link over an extended range by amplifying and repeating the optical signal. A 1+1 optical interface option is also offered and available in the event that two STM-1 links are required to be extended on the same optical route.

VCL-STM-1 Optical Repeater 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.

Complete loop-back facility is supported for system diagnostic and commissioning.

Compact casing and simple operation achieve cost saving and investment protection.

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

1. Dual DC - 48V Inputs (range -18V DC ~ -72V DC)

2. Dual AC 110V AC to 240V AC, 50 / 60 Hz Inputs

Applications

  • To extend 1+0 optical links

  • To extend 1+1 redundant optical links

  • To convert short haul (1310nm) single mode interfaces to long haul (1550nm)  single mode interfaces for extended reach.

  • To convert (850nm) multi-mode optical interfaces to either long haul (1310nm) single mode, or long haul (1550nm) single mode interfaces.
