E1 modem

The BH-OP30 Series E1 fiber optic modem modulatesE1 signals into optical signals totally 2M bandwidth. After the conversion, thesignals are transmitted over fiber optic cable, extending these services rangeup to 120km (72 miles). It is designed to provide a cost-effectivepoint-to-point solution for extending the transmission distance and improvingthe transmission reliability. The BH-OP30 Series fiber optic modem supports differentfiber optic interfaces and can operate with several grades of fiber opticcable.
