4 Wire Data with E&M

Extend Analog Data Circuits with E&M Signaling Over Fiber

The 4 wire data E&M system provides simultaneous transmission of 4-wire data and single or bidirectional E&M over two optical fibers, providing point-to-point isolation of Telco or 4-wire PABX trunk lines using E&M leads.

The 4-wire data supports full duplex constant transmission up to 9600 bps in voice frequency range (300Hz-3.4KHz). 2-wire data is half duplex, and 4-wire data is full duplex. The E&M card interfaces with an E&M input and provides a contact closure on the far end. The cards have convenient E&M input and output status LED indicators.

This fiber link card is designed to be installed into any of the RLH Fiber Link Card Housings, and occupies a single card slot.
