Experience of Maintaining the SFP Optical Module
SFP optical module (Small Form-factor Pluggable) can be easily understood as an upgraded version of the GBIC optical module. SFP optical module is half the size of the GBIC optical module, which is only the thumb-size but can configure on the same panel more than double ports on the same panel. The other functions of the SFP optical module are basically the same as those of the GBIC optical module.

Two important elements about SFP optical modules
According to the wavelength, it can be divided into 850nm/1310nm/1550nm/1490nm/1530nm/1610nm. The one with wavelength of 850nm is SFP multi-mode with transmission distance of 2KM or less;The one with wavelength of 1310/1550nm is SFP single-mode with the transmission distance of over 2KM. The prices of the module with these three wavelengths are relatively cheaper than those of other three wavelengths.

Guide about buying BIDI optical modules
BIDI optical module is a single-fiber bi-directional optical module, the use of WDM technology, launch and receive two different directions of the central wavelength, to achieve the optical signal in a fiber on the two-way transmission. The optical module typically has two ports: the transmit port (TX) and the receive port (RX), and the BIDI optical module has only one port, filtering through the filter in the optical module, and simultaneously transmitting a wavelength optical signal and another (BIDI optical module wavelengths are in combination), so BIDI optical modules must be used in pairs, its biggest advantage is to save fiber resources. This article will introduce the following types of BIDI optical modules.

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.
