Overview of E1 to Fiber Converters


E1 to Fiber Converter with E1 to Ethernet interface, its interface up to 8E1 or T1 circuit and delivers these clear trunks transparently across a fiber link, its transmission distance up to 2.5 Km at 62.5/125 um fiber, 850nm wavelength up to 12 Km at 62.5/125 um fiber, 1300nm wavelength.


The converts making the E1 electrical signal into optical data stream for transport over single mode or multi-mode fiber optic cables, this fiber optic modem extends the transmission distance up to more than 100Km. in addition, this Terminal offers one channel of asynchronous data channels except 2MBIT/S channels which compatible with ITU-T/G.703.

100BASE-FX 1E1 to Fiber Converter Advantages


100BASE-FX 1E1 up to 8E1 converters use reverse multiplexing technology to transmit 10/100Base FX data with bonding multi E1 channels, thus realizing conversion between 1-8 E1 channels and Ethernet FX interface.


It can transmit signals point-to-point from E1 Ethernet FX interface to realize connection between E1 channel and Ethernet FX. Being different from general long-distance bridge, this converter supports flexible configuration of 1 to 8 channels E1 and can detect the number of E1 channel and choose available channel. In the meantime, certain difference of transmitting delay is allowed among E1 channels.


Line rate is 1968Kbit/s for one E1 channel and bandwidth can reach 15744Kbit/s for 8 E1 channels. When used in 10/100Mbps half/full duplex mode, this equipment can be connected with Ethernet switch or hub (integrated circuit machine) to expand transmitting distance and application scope of Ethernet by making full use of large number of E1 channels in current telecommunication network. 


It is an excellent solution for connecting Ethernet broadband. This product can be applied in many fields such as connection of LAN and end offices, video ordering (VOD), remote monitor and E1 interface of switches.  Sopto Also provide framed E1 signal based on ITU-T G.703 to Optical ETH, and transmit it to exchanger, HUB, router, net bridge or other devices through optical 100M channel (100BASE-FX).
