    Data Cabling Dos and Don’ts – Best Rules for Data Cabling
    already talked about importance of proper cabling in 2015 in this article. However, in daily cases, when we see that expensive equipment beeing installed on poorly designed cabling kills all investment as a whole, we decided once again to stress out this optic, and drop in some statistics

    Fiber Optic Cable Preparation, Splicing and Termination
    The fusing of fibers together by an electric arc is known as FUSION SPLICING. It is the most common form of slicing. Its advantages over other slicing techniques are quite numerous, and they include providing the least loss, most robust and reliable joint between two fibers.

    Discussion on 40G to 100G WDM Network Upgrading
    This paper summarizes the problems found in the deployment and maintenance of the existing WDM transmission platform in China, especially the 40G system, and explains the reasons why the WDM network should gradually stop 40G network construction and evolve to 100G network from the perspective of business growth and transmission technology. At the same time, we made some comments and suggestions on 100G network construction mode, network technology applications, network maintenance precautions and so on.

    What is 100G CFP?
    With the continuous development of 5G communication technology, 100G modules are gradually becoming popular. We know that there are many kinds of packages for 100G optical modules. From 2000 to now, the optical module package types have been rapidly developed. Its main package types are: GBIC, SFP, XENPAK, SNAP12, X2, XFP, SFP+, QSFP/QSFP+, CFP, CXP. In the fast-developing network era, some 100G optical modules avoid the risk of being eliminated, and upgraded and revised with the wave of the Internet, such as 100G CFP optical modules.

    What is CWDM SFP? Which areas does it mainly apply to?
    1. What is the CWDM SFP? The CWDM optical module is an optical module using CWDM technology to implement the connection between the existing network device and the CWDM multiplexer/demultiplexer. When used with a CWDM multiplexer/demultiplexer, CWDM optical modules can increase network capacity by transmitting multiple data channels with separate optical wavelengths (1270 nm to 1610 nm) on the same single fiber.

    What is AOC and DAC?
    AOC is the abbreviation of Active Optical Cables, which is called Active Optical Cables in Chinese. AOC active optical is to encapsulate two optical modules and cable together. Because the medium of transmission in the middle is optical cable, AOC optical module, which contains laser devices, has a higher price for DAC. However, its optical aperture is not exposed, it has high reliability, and its working distance can be customized for a long distance of less than 100 meters.

    What is DWDM SFP? What areas does it mainly apply to?
    Dense Wavelength Division Multiplexing (DWDM) technology is capable of transmitting data in an optical fiber using bit wavelength parallel transmission or string line transmission using the wavelength of the laser.It is widely used in different fields of communication networks, including long-distance backbone networks, metropolitan area networks (MANs), residential access networks, and local area networks (LANs).The DWDM optical module is the optical module that uses this technology, so the DWDM optical module has high bandwidth and long-distance transmission characteristics.
