How to calculate the switch’s backplane bandwidth?
The backplane bandwidth of the switch is the maximum amount of data that can be throughput between the switch interface processor or the interface card and bus. The backplane bandwidth marks the total data exchange capability of the switch, and the unit is Gbps, also called the exchange bandwidth. The higher the backplane bandwidth of a switch, the stronger the ability to process data, but also the higher the cost of design.

What is the difference between the SFP port and the Combo port?
Combo interface, also known as optoelectronic multiplexing interface, is the switch device panel on the two Ethernet ports (an optical port and an electrical port). Combo electrical port and its corresponding optical port is logically multiplexed, the user can choose according to the actual network of one of the use, but they can not work at the same time. When one of the port is activated, the other port is automatically disabled.

Do you know the difference between optical fiber and optical fiber cable?
Now many cables use optical fiber cable, because of optical fiber cable stability, the price is much cheaper than ordinary cable. The optical fiber is the main medium for the transmission of information, so before the study of optical fiber communication, we need to know the optical fiber structure and classification, optical fiber transmission principle and optical fiber. Many people have doubts for optical fiber and optical fiber cable and don’t know the difference between optical fiber and optical fiber cable. Let us understand this point first from the optical fiber and optical fiber cable meaning then sees the difference between them.

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.
