Fiber Optic Media Coverters Was Born

- Aug 21, 2017 -

With the widespread use of computers, and now is not just the pursuit of a simple Internet, and with the improvement of quality of life for the speed requirements are getting higher and higher. So the current optical converter is so born, fiber optic converter is generally used in the Ethernet cable can not cover, you must use optical fiber to extend the transmission distance of the actual network environment, and usually located in the optical fiber broadband access layer application.

Fiber converter is an Ethernet transmission medium conversion unit that interchanges short-range twisted-pair electrical signals with long-distance optical signals, and is also known in many places as photoelectric converters. So what is the principle of the fiber converter? Then we went to a detailed understanding of the next.

Principles of fiber optic converters

Now in the long-distance transmission of signals, are using optical fiber transmission, fiber transmission bandwidth is wide, good stability. This requires the computer or telephone or fax generated by the electrical signal (we know that these electronic devices are electronic signals), converted into optical signals to spread in the fiber, which is the photoelectric converter, it can not only the electrical signal Converted into optical signals, optical signals can also be converted into electrical signals.


The role of fiber optic converters

1. With 10M / 100M, duplex / full duplex adaptive function

2. Electric port with MDI-II and MDI-X automatic identification function, automatic detection, automatic learning, good compatibility

3. Has a storage and forwarding storage buffer, effectively improve the transmission efficiency of the termination device, to achieve flow control, broadcast isolation, error detection

4. Support for IEEE802.1q network features can guarantee the backbone of most mainstream products, such as cross-switch VLAN, TRUNK and other functions

5. Support LFP (Link Fault Pass-Through) function, automatically detect any link in the link when the other port to force the other port to stop transmission

Classification of fiber converters

Classification by fiber properties

Single-mode fiber optic transceivers: transmission distance of 20 km to 120 km

Multi-mode fiber optic transceivers: transmission distance of 2 km to 5 km

According to the fiber to the sub, can be divided into multi-mode fiber optic transceivers and single-mode fiber optic transceivers. As the use of different fiber, the transceiver can transfer the distance is not the same, multi-mode transceiver in general transmission distance between 2 km to 5 km, and single-mode transceiver coverage range from 20 km to 120 km. It should be noted that the transmission distance, the reception sensitivity and the wavelength of use of the fiber optic transceiver itself will be different depending on the transmission distance.
