Fiber Media Converter

Unmanaged Fiber Media Converter

  • Introduction

    JHA-GS11 series is complies with IEEE802.3 standards, It is designed to convert data signal between 1000Base-X and 10/100/1000Base-T(X) Ethernet. 
    The media converter is connected between fiber cable and twisted cable, extend your Ethernet network beyond the 100-meter limit imposed by copper cable.
    This converter model can be used as slide-in module to the 14-slot 19" Rack-Mount Chassis.
    Converter is transparent to all protocols, can be used all all areas as Fiber to The Home, Fiber to the Business or Fiber to The Curb.



    Provide status indicators, external power supply (output 5V ~ 50HZ 2A).

    The card design, to facilitate future maintenance and inspection equipment.

    ♦Modular power supply design, function board with separate power supply design, easy to post-maintenance.

    ♦ Unique IC solutions, the chip temperature low, to get rid of plus cooling system, flow control and reduce broadcast storms.

    ♦ High-quality integrated photovoltaic module provides good optical properties and electrical properties to ensure reliable transmission, long life.

    ♦ Operating Mechanism broadcast filtering, address auto-learning and auto-update feature and store and forward.

    ♦ It supports up to 1916 byte long data packet transmission.

    ♦ Missing link to provide remote diagnostics, electrical interface and optical port link link connection diagnostics, dynamic data transmission, full-duplex / half duplex, speed light, easy installation and later maintenance.

    ♦ Ultra-low power consumption of less than 2.5W (Input: AC140 ~ 260V), low heat, stable operation for a long time.
