Wireless optical communication module development, from 2G-3G-4G-5G

Development of wireless optical communication module: 5G network, 25G/100G optical module is the trend. At the beginning of 2000, the 2G and 2.5G networks were under construction. The base station connection began to cut from the copper cable to the optical cable. The 1.25G SFP optical module was... Read More

What is the difference between transmission distance and refractive index of single-mode fiber and multimode fiber?

Transmission distance of single-mode fiber: 64-channel transmission of 40G Ethernet can be as long as 2,840 miles on a single-mode cable. The single mode fiber is mainly composed of a core, a cladding layer and a coating layer.The core is made of a highly transparent material.The cladding has a r... Read More

Two important considerations for using optical modules

Note that the following two points can help you reduce the loss of the optical module and improve the performance of the optical module. Note 1: There are CMOS devices in this chip, so pay attention to prevent static electricity during transportation and use. The device should be grounded well ... Read More
