RLH is pleased to announce our new Analog Phone Fiber Link DIN systems which can transport one or two analog phone lines, or two phone lines with bi-directional contact closure over fiber optic cable. These systems are compatible with all traditional analog phone services, dial-up modems, meters, and fax machines.

Common applications include extending analog lines with contact relay over fiber, providing long distance communication up to 74 mi. (120km), as well as immunity to EMI/RFI and transient surges.

Features include a wide operating temperature, Caller ID and Call Forward Disconnect, making them a true transparent fiber extension. These systems support Ringdown, and standard system powering requirement is 24-48VDC with an optional 125VDC available. They also feature dual redundant power inputs with a system alarm contact relay, and come standard with DIN clip and wall mount ears.

These rugged systems are a great new addition to our Fiber Optic Converters, are manufactured in the USA and covered by our Limited Lifetime Warranty.
