FAQ

​SFP, SFP+, SFP28, QSFP+, and QSFP28 optical module types are not unfamiliar to professionals. These hot swappable modules can be used to connect network switches and other network devices (such as servers or transceivers) for data transmission. But do you understand the specific differences between these modules? Are QSFP28 and QSFP+compatible? Can the SFP28 module be used in SFP+slots? If you have these questions, please read on and this article will take you to find the answers.

Customers may encounter various fault problems when using optical modules, such as whether the optical module model is selected correctly, whether the jumper is used correctly, and other common problems. Customers have the ability to judge and have clear solutions, but for some fault problems that occur during use, such as transmission abnormalities, many customers do not know how to troubleshoot and solve them. This article will focus on teaching you how to troubleshoot and solve common three types of optical module faults.

Fiber to Home (FTTH) technology provides an ideal platform for high-speed broadband access to home users, and brings huge benefits to fixed access networks and advanced wireless networks. PON (Ethernet Passive Optical Network), as a leading technology in fiber to home deployment, is now widely used

What is a PON module?The PON (Passive Optical Network) module is an optical module used in optical fiber communication. PON is a network architecture based on optical fiber technology, deploying optical fiber lines to user terminals and achieving data transmission through passive optical networks.PO

In today's communication networks, PON (Passive Optical Network) technology has become a mainstream access method, providing operators with an efficient, flexible, and reliable network solution. In PON technology, OLT, ONU, ONT, and ODN are four core components that each play an important role.

With the rapid development of optical communication, many scenarios in our work and life have now achieved "optical in and copper out". That is to say, metal medium communication represented by coaxial cables and network cables is gradually being replaced by optical fiber medium.Optical mo

In recent years, with the rapid development of data centers and cloud computing, the demand for high-speed network equipment has also increased. 100G Ethernet has become the mainstream standard for high-speed networks, and in 100G Ethernet, both single-wave optical modules and traditional optical mo

Optical modules are an important component in modern communication systems, and their performance directly affects the transmission quality and stability of the entire communication system. During the use of optical modules, there may be some problems that may cause serious impact on the entire comm

As a key component in optical communication systems, optical modules act as transmission media between network devices to send and receive data. Currently, there are many articles on optical modules on the market, but only a small number mention the internal structure of optical modules. This
