    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.

    Optical module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic devices include transmitting and receiving parts. Simply put, the function of optical module is photoelectric conversion. The transmitter converts electrical signals into optical signals. After transmission through optical fibers, the receiver converts optical signals into electrical signals.

    When we are looking for 10G sfp, we have the four most common descriptions of 10GBase-SR, 10GBase-LR, 10GBase-ER and 10GBase-ZR. Which four describe which SFP+ optical module is represented in the Ethernet specification? Let us take a look at the different optical modules represented by different descriptions today.

    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.

    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.

    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.
