What is the difference between SFP28 and QSFP28?
Driven by the increasing demand for bandwidth requirement, the 25G Gigabit Ethernet or 25GBASE-T standard has been released in recent years. Then 25G SFP28 assemblies like SFP28 transceiver and SFP28 DAC & AOC, come into being. Though the SFP28 assemblies have been used in a wide variety of high-density and low-power 25 Gigabit Ethernet connectivities, they are still different in optical communications. Why? The following part will uncover it.

40G & 100G Optical Transceivers Basics
A recent report from market research company LightCounting talks about the 40G & 100G optical transceivers basics, here is the details.40G and 100G has two main types in the data center. Short reach (SR4) for ~100 meters transmission on multi-mode fiber and Long Reach (LR4) for 100 meters to 10km using single-mode fiber. We can use SR/LR transceivers to connect compute clusters and various switches layers in data centers.

HOW DO I CALCULATE FIBER OPTIC LINK BUDGET?
In order to accurately calculate fiber optic link budget, you should know two concepts: installation loss and AC losses.What are installation losses?Installation loss is also called DC loss. It refers to optical losses caused by fiber optic cabling plant. This includes fiber transmission loss, attenuation versus wavelength and connector and splicing loss.

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.
