  10/100 Ethernet Optical Fiber Transceiver

  IEEE802.3u 100Mbps fast Ethernet optical fiber transceiver supports two mediums, 100Base-TX and 100Base-FX which are used for network connections. The fiber transceiver, which is also called medium converter or Ethernet optical terminal, is used for the equivalent transformation between two medium signals so that they can be connected conveniently and economically. The transceiver can be used either as an independent unit or a package board in the 19-inch fiber transceiver subframe (it contains 10 unit at most) placed in the central distribution rack.

  
  TRXE1-10Base-T Communication Interface  Converter

  TRX E1-10/100Base-T developed by Hengguang Technologies, employs the clarity E1 transmission channel in accordance with ITU-T G.703 advice and IEEE802.3 standard with independent intellectual property. It is a kind of remote transmission equipment transmitting 10 Base-T data. With an independent structure, TRXE1-10Base-T can transmit 10Base-T data through E1 channels and extend work distance of the interface between two Ethernets through E1 channels such as optical fiber, microwave DDN nets and so on.
   It can use the existing communication network structures and interfaces efficiently without impropriating optical fiber core or additional equipment.

 Its optical fiber covers more than 60Km. The MODEM is widely used in various spot data communication such as SCADA system, data collecting system, computer distributing system, and so on. The OTS232 can compose star network, ring network or simple point-to-point system. Taking no participation to the communication protocols between data equipment, OTS232 transmits transparent channels in point to point mode.

                               

       
    E1/V35/RS232  Interface Converter              

  E1V35RS232 interface converter is designed for the transformation between RS232 (V.24) and E1, or between N×64Kb/s V.35 and E1 interface.
  The E1 interface adopts Siemens-type L9 coaxial as physical connector, and the RS232/V.35 interface adopts DB15 type. The power feeding can be of AC220 or DC-48V.
  The RS232 interface rates 0-57.6Kbps.
The V.35 interface rates N×64Kbit/s, N=1-32 to make the bandwidth flexible and frame/unframed also flexible. The timing mode can be set to DTE or DCE.
  With a small dimension and good reliability, the interface converter is used in data communication and SCADA systems.

        
   OTS155E4 Interface Converter 
   
   It is used for the one E4 to STM-1 or three E3 to STM-1. E3, E4 interfaces conform to the protrol signed by PDH system. The interface adopts Siemens-type L9 coaxial as physical connector, and optic interface is used for STM-1 physical connector. Wavelength is 1310nm or 1550nm. 19 inches in width, 1U in height, the power supply can be of AC220V or DC-48V. The LED indicator on the front panel to indicate the working conditions and the alarming. The overhead processing of the STM-1 is not used by STM1/E4E3.              

 4E1-100Base_T converter

  4E1-100Base_T converter employs the clarity 1-4  E1 transmission channels in accordance with ITU-T G.703 advice , G.704 and G.823 standard. The Ethernet adopts 10/100M, Full Duplex, Half Duplex and has the capability of the MDIX, support VLAN and the 2048 byte as the most. 4 channels of E1 interfaces can be configured flexible according to the number of the E1 channels in the project. Actomatic error detection function, and set the threshold of the error detection.  Permitting the largest delay time is 16ms between the E1 channels. Network managment , control the E1 interface and the state of the LAN interface both the end and the remote. Either AC 220V or DC -48V.
