Is DWDM and OTN the same?
Jul 24 , 2024
DWDM and OTN are two different technologies in the field of optical communication. DWDM is an optical transmission technology used to simultaneously transmit multiple wavelengths of optical signals in optical fibers, thereby expanding the transmission capacity of optical fibers, increasing network bandwidth, and supporting long-distance transmission. OTN is a network transmission tec...

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....

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...

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 are the Types of OLP? —OLP 1+1 vs OLP 1:1
May 30 , 2024
Optical Line Protection (OLP) is a kind of optical fiber line automatic switching protection device, which is an automatic monitoring and protection system independent of the communication transmission system, completely built on the physical link of optical cable.If the primary fiber fails, the OLP can automatically switch from the primary fiber path to another alternate fiber path through real-t...
