PON refers to a passive optical fiber network, which is an important way for broadband access network services to be carried. PON technology originated in 1995. Later, according to the difference between the data link layer and the physical layer, PON technology was gradually subdivided into APON...

Optical fiber transmits signals in the form of light pulses, and uses glass or plexiglass as the network transmission medium. It consists of fiber core, cladding and protective cover. Optical fiber can be divided into Single Mode fiber and Multiple Mode fiber. Single-mode optical fiber only prov...

What is FTTx? FTTx is “Fiber To The x” and is the general term for fiber access in fiber optic communications. x represents the destination of the fiber line. Such as x = H (Fiber to the Home), x = O (Fiber to the Office), x = B (Fiber to the Building). FTTx technology ranges from the...

SFP optical modules can be inserted into SFP+ ports in most cases. Although the specific switch model is uncertain, according to experience, SFP optical modules can operate in SFP+ slots, but SFP+ optical modules cannot operate in SFP slots. When you insert an SFP module in the SFP+ port, the spe...

With the development of science and technology, the speed of urban informatization is accelerating, and the requirements for communication technology are becoming higher and higher. Optical fibers are becoming more and more popular in communication because of their advantages of fast transmissio...

The function of the optical module is photoelectric conversion. The transmitting end converts the electrical signal into an optical signal. After transmission through the optical fiber, the receiving end converts the optical signal into an electrical signal. It is mainly divided into: SFP, SFP+,...
