In the past two years, due to the optical industry to "100G network deployment" as the center of the development of 100G optical modules in the data center market can be rapid development. Currently on the market to launch the 100G optical module types are: CXP optical module, CFP optical module, CFP2 optical module, CFP4 optical module and QSFP28 optical module.Construction of 25G/100G

40G QSFP+ LR4 optical modules are widely used in 40G networks, which contain two types of 40G QSFP+ LR4 CWDM4 optical modules and 40G QSFP+ LR4 PSM4 optical modules. The former is used to connect WDM links and the latter is used to connect parallel single-mode fiber links, but what is the difference between these two types of modules?First, CWDM4 and PSM4 both terminology analysisCWDM (Coarse Wave

With the development of optical networks, especially after the emergence of 5G networks, data transmission has risen dramatically, and 100G optical modules are gradually widely used in various optical networks to rapidly improve the transmission capacity and rate of optical networks.For applications over 10km in 100G networks, there are two main solutions: 100G ER4 (40km), 100G ZR4 (80km), using Q

With the rapid development of data centers, the demand for data transmission grows, driving the network to higher bandwidth and higher density. Currently, a new generation of 400G optical module package type has appeared on the market - 400G QSFP-DD, where "DD" refers to double density, that is to say, the number of channels of 400G QSFP-DD has been changed from four to eight, which can

The 100G QSFP28 optical module is a high-speed optical communication module commonly used in application scenarios such as data centers, cloud computing and high-performance computing. Common types of this module, including SR4, LR4, ER4, PSM4, ZR4, SR BIDI and SWDM4.I. 100GBASE-SR4 QSFP28 Optical ModuleSR4 (Short Range 4) is a short range multimode fiber optic module that supports a maximum trans
