Development of Optical Fiber Access Technology and Optical Fiber Communication Technology

[Introduction] The wavelength division multiplexing technology can make full use of the huge bandwidth resources brought by the low-loss area of single-mode fiber. According to the frequency (or wavelength) of the light wave of each channel, divide the low-loss window of the fiber into several ch... Read More

Introduction to Fiber Optic Transceivers

Optical fiber transceiver is an Ethernet transmission medium conversion unit that exchanges short-distance twisted pairs to pair electrical signals with long-distance optical signals. Also known as a photoelectric converter in many places. This product is generally used in the actual network envi... Read More

Applications of Fiber Optic Transceivers

Different perspectives make people have different understandings of fiber optic transceivers: For example, according to the transmission rate, it is divided into single 10M, 100M fiber optic transceiver, 10/100M adaptive fiber optic transceiver and 1000M fiber optic transceiver> According to t...
