1.Laser category A laser is the most central component of an optical module that injects current into a semiconductor material and emits laser light through photon oscillations and gains in the cavity. At present, the most commonly used lasers are FP and DFB lasers. The difference is that the sem...

Basic concept of optical fiber communication. An optical fiber is a dielectric optical waveguide, a waveguide structure that blocks light and propagates light in the axial direction. Very fine fiber made of quartz glass, synthetic resin, etc. Single mode fiber: core 8-10um, cladding 125um Multimo...

The main function of the fiber optic connector is to quickly connect the two fibers so that the optical signal can continue to form an optical path. Fiber optic connectors are mobile, reusable, and are the most essential and most used passive components in optical communication systems.The fiber ...

An optical module is a photoelectrically converted electronic component. Simply speaking, an optical signal is converted into an electrical signal, and an electrical signal is converted into an optical signal, which includes a transmitting device, a receiving device, and an electronic functional...

Development of wireless optical communication module: 5G network, 25G/100G optical module is the trend. At the beginning of 2000, the 2G and 2.5G networks were under construction. The base station connection began to cut from the copper cable to the optical cable. The 1.25G SFP optical module was...

Transmission distance of single-mode fiber: 64-channel transmission of 40G Ethernet can be as long as 2,840 miles on a single-mode cable. The single mode fiber is mainly composed of a core, a cladding layer and a coating layer.The core is made of a highly transparent material.The cladding has a r...
