What are active (AON) and passive (PON) optical networks?

What is AON? AON is an active optical network, mainly adopts a point-to-point (PTP) network architecture, and each user can have a dedicated optical fiber line. Active optical network refers to the deployment of routers, switching aggregators, active optical equipment and other switching equipmen... Read More

The working principle and application of optical module in optical transmission

In the field of communication, electrical interconnection transmission of metal wires is greatly restricted due to factors such as electromagnetic interference, inter-code crosstalk and loss, and wiring costs. As a result, optical transmission was born. Optical transmission has the advantages of ... Read More

Introduction and application of EPON optical module and GPON optical module

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... Read More

What is optical fiber? Characteristics and classification of optical fiber

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... Read More

Quickly understand FTTx FTTC FTTB FTTH

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... Read More

Can SFP optical modules be used in SFP+ slots?

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... Read More
