Basic knowledge about fiber optic transceivers

1.1 Basic function module The optical fiber transceiver includes three basic functional modules: photoelectric media conversion chip, optical signal interface (optical transceiver integrated module) and electrical signal interface (RJ45). If equipped with network management functions, it also inc... Read More

Analysis of optical fiber fusion technology standards

Optical fiber fusion splicing process Optical fiber connection methods can be divided into two types: one is the permanent connection method that cannot be disassembled and assembled once connected, and the other is the connector connection method that can be repeatedly disassembled and assembled...

POE switch technology and advantages introduction

The PoE switch is a switch that supports power supply to the network cable. Compared with the ordinary switch, the power receiving terminal (such as AP, digital camera, etc.) does not need to be wired for power supply, and the reliability of the entire network is higher. The difference between P... Read More

What is an optical splitter and what are the important technical indicators?

The optical splitter is one of the important passive devices in the optical fiber link, and mainly plays the role of splitting. It is generally used in the optical line terminal OLT and the optical network terminal ONU of the passive optical network to realize the optical signal splitting. The op... Read More

Comprehensive analysis of the difference between fiber jumpers and pigtails and precautions for use

There are many types of patch cords and pigtails. It is worth noting that fiber pigtails and patch cords are not a concept. The main difference between fiber optic patch cords and fiber optic pigtails is that only one end of the fiber optic pigtail has a movable connector, and both segments of th... Read More

What should I do if the temperature of the optical module is too high? How to solve?

The optical module is a relatively sensitive optical device. When the operating temperature of the optical module is too high, it will cause problems such as excessive transmit optical power, received signal error, packet loss, etc., and even burn the optical module directly in severe cases. If t... Read More
