    1*1000Base-X SFP Slot + 1*10/100/1000Base-T(X) RJ45 Port


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.



    ♦ 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.
