    1. 详细信息

    HC-OE120-8E1U(8E1UP)is the series of optical transmission device with digital optical fiber. 8E1U has single optical port, and 8E1UP has double optical designed to achieve the 1+1 optical-line protection.


    HC-OE120-8E1U(8E1UP)provides customers with 8 E1 interfaces, 1 channel of Ethernet data, 1 channel of Asynchronous RS232 data, and 1 channel of service data. The single board design with 19-inch 1U structure makes installation and maintenance extremely easy for operators.


    This series perfectly fits for:

    •  Relaying between local network,

    • Digital relaying between point-to-point local switches and user switches,

    • Transmission requirements of wireless base stations, computer networks, and teleconferences



    Features:

    • Advanced large-scale integrated circuit meets international standards

    •  Highly integrated optical devices and DPLL (Digital Phase-locked Loop)

    • Circuits highly integrated in the disk with small sized provides excellent reliability

    • Compact structure, low power consumption, easy installation and maintenance

    • Ideally fit for small-capacity optical transmission equipment
