FIBER OPTIC LINKS


PRODUCT DESCRIPTION
RLH Fiber Optic Link cards are industrial hardened copper-to-fiber media converters, designed for outside plant and power station environments. Fiber Optic Link Cards are designed to be installed into RLH card housings, and may be configured for single line or multiple line applications.

POWER INFORMATION

Most Fiber Optic Link CO (Central Office) cards have the unique ability to operate from telephone line power (simplex current) eliminating the need for a local power source.

From the CO side location a copper derived signal is transmitted over an all-dielectric fiber optic cable (single-mode or multimode).

The Sub (Subscriber) side of the Fiber Optic Link system recreates the copper signal.

POWER SUPPLY OPTIONS
We carry an extensive line of AC/DC power supplies, converters, solar power and battery backup systems.
