The 2 Channel POTS (Plain Old Telephone Service) Fiber Link Cards are fully featured and hardened for substation and critical applications. These cards operate over a wide temperature range and have 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. These cards are fully compatible with all traditional POTS services, dial-up modems, meters, & fax machines. Fiber Link Cards are designed and Made in the USA, and are covered by our 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.
