Optical fiber communication is the main transmission means of modern communication networks. Its development history is only one or two decades. It has experienced three generations: short-wavelength multimode fiber, long-wavelength multimode fiber and long-wavelength single-mode fiber.The use of...

With the rapid development of the Internet, the transmission distance of the twisted pair and the influence of electromagnetic interference are limited, which restricts the development of the network. Therefore, the optical transceiver has emerged.The use of fiber optic transceivers replaces the ...

After the optical module is installed, testing its performance is an essential step.When the optical components in the entire network system are supplied by the same vendor, if the network system can work normally, there is no need to separately test the sub-components of the system.However, most...

Optical Fiber Communication Optical fiber communication technology has emerged from optical communication and has become one of the main pillars of modern communication. It plays an important role in modern telecommunication networks.As an emerging technology, optical fiber communication has deve...

At present, the competition around 5G is rapidly heating up around the world, and countries with leading technologies are competing to deploy their own 5G networks.South Korea has taken the lead in launching the world’s first commercial 5G network in April this year.Two days later, US telec...

Optical communication principle The communication principle is as follows.At the sending end, the transmitted information (such as voice) should be first converted into electrical signals, and then the electrical signals are modulated to the laser beam emitted by the laser (light source), so t...
