SFP Media Converter
The GEZHI GS-3100 is a Fiber media converter designed to convert 1000BASE-SX/LX/LH fiber to 1000Base-T copper media or vice versa.

  •  SFP Media Converter 

    GEZHI SFP Media Converter Designed under IEEE802.3ab 1000Base-T and IEEE802.3z 1000Base-SX/LX/LH standards, the GS-3100 is designed for use with multi-mode/single-mode fiber cable utilizing the LC-Type connector. It works at 850nm on both transmitting and receiving data when adopting multi-mode fiber and 1310nm on both transmitting and receiving data when adopting single-mode. 

    Other features of this module include the ability to be used as a stand alone device (no chassis required) or with 19´´system chassis, Auto MDI/MDI-X for TX port, and front panel status LEDs. The GS-3100 will transmit at extended fiber optic distances utilizing multi-mode fiber up to 0.55 kilometers and 10 kilometers when utilizing single-mode fiber.


    ♦ Accord to IEEE802.1 10Base-T, IEEE802.3u 100Base-TX, IEEE802.3 100Base-FX, IEEE802.3z 1000Base-SX/LX

    ♦ MDI/MDI-X auto negotiation, 10M/100M auto negotiation

    ♦ Supports full /half duplex, Point-to-point transparent transfer

    ♦ With one SFP slot

    ♦ Plug-and-play, easy to installation

    ♦ Can insert to 2U 19", 14 slots Rackmount(power external)



    ♦ 10/100/1000Mbps Gigabit optical Ethernet long-distance transmitting network



    The high performance Fiber Link Ethernet Extenders provide up to 80KM of Ethernet extension over single-mode fiber. The Model GS-3100 is ideal for campus networks, connecting remote LANs, and facilitating the optical last-mile connection to the metropolitan-area network (MAN) and beyond.   It provides a cost effective plug-and-play solution for long-range 10Base-T, 100Base-TX, 1000Base-TX, Ethernet extensions and added benefit of 10/100/1000M auto-negotiation, making it the perfect choice when planning future upgrades of 10Base-T networks. Ethernet Fiber converters are ultra-miniature in size and feature a shielded RJ45 Ethernet jack, SFP style fiber-optic connections. Built-in auto-sensing capabilities enable full or half-duplex Ethernet operation with no configuration required!
