4RU FIBER OPTIC LINKCARDS


PRODUCT DESCRIPTION
RLH 4RU Fiber Optic Link cards are industrial hardened copper-to-fiber media converters, designed for harsh environments, outside plant and power station applications. Fiber Optic Link Cards are designed for stand alone, single or multiple line applications.
QUICK LINKS - 4RU PLUG-IN CARDS
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.
