Transport 2 Circuits of ADSL Over Fiber

Product Overview

The RLH 2 Channel ADSL Fiber Link Card system supports two channels of ADSL copper service over a single pair of singlemode or multimode fiber optic cable. This environmentally hardened system converts the copper signals into an optical signal over fiber, then converts the fiber optic signal back into 2 Wire DSL copper service for customer use.

Transmitting ADSL signals over fiber optic cable allows for network extension over long distances, and provides electrical isolation between both ends of the network. The RLH ADSL fiber system is compatible with DSL download data rates of up to 2.75Mbps.

Each card requires a 44-56VDC 100mA local power source to operate. RLH carries several compatible power supplies, but any compatible DC power source is acceptable.This hardened, rugged system is covered by our Limited Lifetime Warranty.

This fiber link card is designed to be installed into any of the RLH Fiber Link Card Housings, and occupies a single card slot.
