How does single-mode fiber continue?
A single-mode fiber is a fiber that transmits only a single base die at a given operating wavelength. He does not exist mode dispersion, so single-mode fiber has a very wide transmission band, used in long-distance, high-capacity transmission. Single-mode fiber core is very fine, core diameter of only 8-10μм, cladding diameter of 125μм, can be made very long, but in order to manufacture, transport, construction convenience, usually the cable length of the factory 1 - The Single-mode fiber transmission loss is now low as low as 0.2dB / (1.55μм), cable connection length is not easy to less than 2.

XFP transceiver troubleshooting and handling methods
Failure reasons: XFP transceiver failure may be due to the machine, or the interface caused by more dust, which requires us to fault maintenance process, pay attention to observe the fault inside the machine, whether there is more dust, if it is , Should be carried out first dust, and then follow-up to determine fault maintenance.

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.
