INFORMATION
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 4 wire data supports constant transmission of
voice frequency ranging from 300Hz-3400Hz which is suitable for a
wide range of radio and SCADA applications. The devices can be
ordered with dual fiber or single fiber transceivers. This RLH Fiber
Link system is designed and made in the U.S.A. and covered by our
Limited Lifetime Warranty.
