What is an external media converter?
Apr 19 , 2024
An external media converter is a device used in networking to convert signals between different types of media or network interfaces. Its primary function is to enable communication between network devices that use different transmission media, such as copper wires and fiber optic cables. Here's a breakdown of its key components and functions: Media Conversion: External media converters facilitate...

DCM- Dispersion Compensation Module
Jun 05 , 2024
In fiber communication, optical pulses extend due to dispersion and tend to overlap with adjacent pulse periods. This causes interference between adjacent bits and leads to a high BER.At a high bit rate equal to the pulse width, the bit error rate (due to dispersion) will become too large.The dispersion compensation module (DCM) (also known as the dispersion compensation unit, DCU) c...

What is EDFA?How does EDFA work?And what are the types of EDFA?
Jun 13 , 2024
What is EDFA? EDFA is an optical repeater device that is generally used in the C and L bands, almost between 1530 and 1565nm.The fiber is doped with the rare earth element erbium, allowing the glass fiber to absorb light at one frequency and emit light at another frequency.At present, EDFA optical fiber communication is usually used to compensate for the optical fiber loss in long-distance optical...

Optical Amplifiers : EDFA vs SOA
Jun 19 , 2024
In the optical fiber communication,because the optical signal will gradually weaken during the transmission process because of the optical decay, the optical amplifier needs to be used to enhance the signal intensity, so that the signal can be transmitted to a distance.EDFA and SOA are two common optical amplifiers, each have different characteristics and application scenarios....
