How do I check the optical signal strength of an SFP optical module?
As we all know, SFP optical modules support a variety of applications, such as Fiber Channel (FC) switches, SONET / SDH networks, Gigabit Ethernet, high-speed computer links, CWDM and DWDM interfaces. When the SFP optical module and the switch are connected, the optical signal strength is the key parameter to ensure the normal operation of the whole connection. This article describes the optical signal measurement method for SFP optical modules and how to view the optical signal strength of SFP optical modules.

Optical module interface type
SFP (Small Form-factor Pluggables) can be easily understood as an upgraded version of GBIC. The SFP module (which is half the size of the GBIC module and can be configured with more than double the number of ports on the same panel. Since the SFP module is basically the same as the GBIC function, it is also known by some switch manufacturers as miniaturized GBIC -GBIC).

Differences between SFP and SFP +
Many people do not know the difference between sfp and sfp +, so sometimes bring unnecessary trouble. 10G module has experienced from the 300Pin, XENPAK, X2, XFP development, and ultimately achieved the same size and SFP transmission 10G signal, which is SFP +. SFP by virtue of its small and low cost and other advantages to meet the equipment on the high demand for optical modules, from the 2002 standard implementation, to 2010 has replaced XFP 10G market mainstream.

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.
