Extend Voice and Contact Closure Over Fiber
The RLH 2 Channel Plain Old Telephone Service (POTS) DIN Fiber Link system transports two analog phone lines over fiber optic cable. Each unit also features bi-directional contact closure for remote relay transportation. The system will operate over a wide temperature range and has been designed to provide reliability in harsh environments.
Common applications include extending analog lines over fiber for the benefit of electrical isolation, to achieve long distances, or through noisy environments to reduce EMI. The system is compatible with all traditional analog phone services, dial-up modems, meters, and fax machines.
A comprehensive set of LED’s on the front panel indicate the status of the power, fiber, phone lines, and contact closure. The standard system powering requirement is 24-48VDC, with an optional 125VDC available. This rugged system also features dual redundant power inputs with a system alarm contact relay, and comes standard with DIN clip and wall mount ears.
