Extend Two 4 Wire Voice Frequency Signals Over Fiber Optic Cable
Product Overview
This industrial fiber optic media converter is designed to extend two 4 Wire Voice Frequency Signals over fiber optic cable. By extending 4 Wire signals over fiber cable you gain the advantage of sending the signal long distances, up to 120km, as well as gain noise immunity to RF and Electromagnetic Interference.
This system transports two circuits of 4 Wire Data and supports E&M signaling. The devices can be ordered with dual fiber or single fiber transceivers. The 4 wire data supports constant transmission of voice frequency ranging from 300Hz-3,400Hz which is suitable for a wide range of radio and SCADA applications. This RLH Fiber Link system is designed and made in the USA and covered by our Limited Lifetime Warranty.
