  Optical fiber transceivers  are relatively abundant, mainly including rack-mounted optical transceivers, desktop optical transceivers and card-type optical transceivers. In addition, there are many manufacturers of fiber optic transceivers on the market. In purchasing, buyers must also consider the compatibility of the product with the surrounding environment and the stability and reliability of the product itself in addition to the price. The following are the application functions you need to understand when buying a fiber optic transceiver. Optical fiber transceiver is a kind of network equipment for mutual conversion of electrical and optical signals. It is a simplified optical transceiver, which is widely used in optical communication equipment. Optical fiber transmission equipment such as telephone optical transceivers and optical fiber access equipment can achieve transmission between devices through optical transceivers. Single-mode and multi-mode optical transceiver...

  Fiber optic transceivers  usually have the following basic characteristics: 1. Provide ultra-low latency data transmission. 2. It is completely transparent to the network protocol. 3. A dedicated ASIC chip is used to realize data line-speed transmission. Programmable ASIC concentrates multiple functions on one chip, and has the advantages of simple design, high reliability, and low power consumption, which can enable equipment to obtain higher performance and lower cost. 4. Rack-type equipment can provide hot-swappable functions for easy maintenance and uninterrupted upgrades. 5. The network management equipment can provide functions such as network diagnosis, upgrade, status report, abnormal situation report and control, and can provide a complete operation log and alarm log. 6. Most equipment adopts 1+1 power supply design, supports ultra-wide power supply voltage, and realizes power supply protection and automatic switching. 7. Support an ultra-wide operating temperature ...

  Features of  CWDM mux Demux products : 1. Low insertion loss 2. Low PDL 3. High channel isolation 4. Excellent environmental reliability Although the DWDM Mux Demux module is designed to multiplex multiple DWDM channels into one or two optical fibers, it is also the most reasonable solution to meet the needs of big data transmission. The general configuration of DWDM mux is 4, 8, 16, and 32 channels. For example:  Dual Fiber 8CH 1470nm~1610nm CWDM MUX DEMUX With 1310nm and Monitor Port Features of  DWDM  mux D emux  products : 1. Insertion gains and losses are low and isolation is high. 2. Simple installation without configuration, easy to disassemble and clean. 3. Fully transparent on all data rates and protocols. 4. Completely passive, no power supply, no cooling, etc. For example:  Dual Fiber 40CH C21-C60 DWDM MUX DEMUX Summary: It is foreseeable that in the all-optical network that is expected to be realized in the future, the up/down and cross-c...

  Wavelength Division Multiplexer (WDM) is a technology that simultaneously transmits multi-wavelength optical signals on a single optical fiber. The wavelengths of the digital signals carried by these optical signals can be at the same rate and in the same data format, or at different rates and in different data formats. By adding new wavelength characteristics, the network capacity is determined according to user requirements. For WDM below 25Gb/s, current technology can completely overcome the limitations imposed by fiber dispersion and fiber nonlinear effects to meet various requirements for transmission capacity and transmission distance. WDM realizes two-way communication and low-cost upgrade of optical network capacity. The wavelength division multiplexer can be divided into a wavelength divider at the transmitter and a wavelength division multiplexer at the receiving end. The optical multiplexer is used at the transmission end of the transmission system and is a device with...

  There are many different classifications of   fiber optic transceiver s , and in actual use, most of the attention is paid to the categories that are distinguished by different fiber connectors: SC connector fiber optic transceivers and FC/ST connector fiber optic transceivers. When using fiber optic transceivers to connect different devices, you must pay attention to the different ports used. ​ 1. Connection of fiber optic transceiver to 100BASE-TX equipment (switch, hub): Make sure that the length of the twisted pair cable does not exceed 100 meters; connect one end of the twisted pair cable to the RJ-45 port (Uplink port) of the fiber optic transceiver, and the other end to the RJ-45 port of the 100BASE-TX device (switch, hub) (Ordinary mouth). 2. Connection of fiber optic transceiver to 100BASE-TX equipment (network card): Make sure that the length of the twisted pair is no more than 100 meters; connect one end of the twisted pair to the RJ-45 port (100BASE-TX port) of t...

  In the next five years, 5G network (fifth-generation mobile communication technology) will become a hot spot in the field of information and communication, and the rapid development of the field of information and communication. The advance construction and upgrade of the bearer network will promote the continuous increase in the demand for optical components in the telecom network. At the same time, the data center network in the cloud computing era Demand has exploded, and the demand for high-speed optical modules such as   25G  SFP28  optical modules   and   100G QSFP28 optical modules   has grown rapidly. With the deployment of 5G, operators need to deploy wider bandwidths to achieve high-traffic data applications, such as telemedicine, VR, 4K video, etc. Therefore, each layer of the mobile network must have higher speeds, which also promotes the SFP28 25G optical Module / Application of QSFP28 100G optical module. In addition to the huge demand ...
