Lead: 100G Ethernet from research to commercial, need to solve the key technologies of interface, packaging, transmission, key components, etc. The key technologies of the current 100G Ethernet interface include physical layer, channel convergence technology, multi-fiber channel and wave Sub-mult...

1.Basic structure of PON PON (Passive Optical Network) PON is a single-fiber bidirectional optical access network using a point-to-multipoint (P2MP) structure. The PON system is composed of an optical line terminal (OLT), an optical distribution network (ODN), and an optical network unit (ONU) on...

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...
