XFP Transceiver Selection Details
How do I select an XFP transceiver?Some chips on the market can only use full-duplex environments, can not support half-duplex, such as access to other brands of switches (SWITCH) or hub (HUB), and it uses half-duplex mode, it will cause serious Conflict and packet loss.

Do XFP transceiver need to be used in pairs?
XFP transceiver must be used in pairs? XFP transceiver is not divided into one is a hair is made? Or just as long as the two XFP transceiver can form a pair of use? If the XFP transceiver must be used in pairs, then a pair of words is not necessarily the same brand with the model? Or can be casually brand can be used in combination.

XFP transceiver perform better than standard
Fiber optic cable manufacturers through the attenuation and bandwidth of the two parameters to illustrate the characteristics of the product. Although these parameters are the basis of good performance, but they still can not fully reflect the performance of cable.

The role of optical modules
The XFP module is a connection module which plays the role of photoelectric conversion, in which the transmitting end converts the electrical signal into an optical signal, and after the optical fiber is transmitted, the receiving end converts the optical signal into an electrical signal. It consists of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic devices include two parts: transmit and receive.

Single fiber transceiver and dual fiber transceiver difference
XFP transceivers are single and double fiber. A dual-fiber transceiver that uses two cores to transfer data, one for hair and one for reception. Single-fiber transceiver, that with a single core both received data. Now the light reuse technology is mature, single or double fiber transmission data can complete the task. But the single-fiber transceiver is more expensive than the dual-fiber transceiver. Single-fiber transceiver, through an SC interface for the transmission of data. Dual fiber transceivers, two SC fiber ports are used to transmit data.

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.
