  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • How to distinguish whether an optical fiber module is single-mode or multi-mode?

    As an important part of optical network transmission, optical fiber module functions as photoelectric conversion, so that signals can be transmitted in optical fibers. So, do you know how to distinguish whether an optical fiber module is single-mode or multi-mode? Here are a few ways to distingui...

  • Precautions for using 10G SFP+ 10G BIDI single fiber optical module

    Optical modules can be classified into single-fiber and dual-fiber according to the number of interfaces. Dual-fiber optical modules have two optical fiber interfaces, and single-fiber optical modules have only one optical fiber interface. In addition to the difference in optical fiber interfaces...

  • Several conventional applications of fiber optic transceivers

    The optical fiber transceiver essentially only completes the data conversion between different media, which can realize the connection between the computers or switches at both ends within 0-100KM, but there are more extensions in practical applications. Then, what are the specific applications o...
