A converter, also called a transceiver, is a device comprises both atransmitter and a receiver which are combined and share common circuitry or a single housing. When no circuitry is common between transmit and receive functions, the device is a transmitter-receiver. The term originated in the early 1920s. Technically, transceivers must combine a significant amount of the transmitter and receiver handling circuitry .

Fiber media converter, also known as fiber transceivers or Ethernet media converters, are simple networking devices that make it possible to connect two dissimilar media types such as twisted pair such as Cat 5 or Cat 6 cable with fiber optic cabling. To be plainer, they receive data signals, sent via one media, convert the signals and then transmit the signals into another. Fiber optic media converters can convert the signals sent from copper cable to signals that run on the fiber cable. They are copper to fiber or fiber-to-fiber conversion devices. They are important in interconnecting fiber optic cabling-based systems with existing copper-based, structured cabling systems. Fiber Ethernet media converters support a variety of communication protocols including Ethernet, Fast Ethernet, fiber media converter gigabit. There are single mode converter and multi-mode converters. For single mode converter, there are dual fiber type and single fiber type, in which the fiber cable functions both as transmitting media and receiving media. While for multi-mode converter, there are only dual fiber types. Single fiber media converters are also called WDM fiber optic converters.

Fiber media converter can connect different Local area network (LAN) media, modifying duplex and speed settings. For example, switching media converters can connect legacy 10BASE-T network segments to more recent 100BASE-TX or 100BASE-FX Fast Ethernet infrastructure. For another, existing Half-Duplex hubs can be connected to 100BASE-TX Fast Ethernet network segments over 100BASE-FX fiber. When expanding the reach of the LAN to span multiple locations, fiber transceivers are useful in connecting multiple LANs to form one large campus area network that spans over a wide geographic area.

Our fiber media converters are designed to meet the needs for massive fiber network deployment and able to extend a legacy copper based Ethernet network via fiber optic cable to a maximum distance up to100Km. It is fully compliant with IEEE802.3u standards, support bi-directional transmission of 10/100/1000MFast IP Ethernet data or over one multi-mode or single-mode fiber. We can offer compact, cost-effective, low dissipative, high reliable and stable fiber media converter which can be used in standalone applications, or Rack-Mounted applications where multiple media converters can be inserted into a rack-mount chassis (up to 16 units), and allowing all the converters to be powered by a single internal power supply.
