With the popularization of 100G Ethernet, the latest two types of 100G QSFP28 optical transceivers, 100G QSFP28 CWDM4 optical transceiver, and QSFP28 PSM4 optical transceiver are well recommended for the […]

For an optical transceiver, dispersion also is the factor not to be ignored. Maybe many people are unfamiliar with this term and have little knowledge of what impacts it has on the optical transceiver module. Then […]

Maybe most of the people have a knowledge of SDI(Serial Digital Interface), but when it really comes into it, how many people are there indeed familiar with it? Then today, Gigalight will make a comprehensive […]

With the popularization of optic fiber communication, the adoption of optic fiber for high-definition video transmission has been the reality. Furthermore, there appear various video optical terminal devices in […]

SDI SFP optical module is also called as digital video optics or SDI（serial digital interface）optical transceiver. This optical transceiver mainly supports video pathological signal of SDI device. Different fro […]

SFP optical transceiver is familiar to most of the people. By comparison, video SFP optical transceiver, also regarded as digital video transceiver or Serial Digital Interface（SDI for the short）video tra […]

As the network is gradually upgraded from 25G-40G-100G, people have more demands on the 100G optical transceiver to deploy data centers or Ethernet. Maybe most people are familiar with 100G optical transceiver […]

With the development of network tech and other communication techs, metropolitan area network(MAN) appears to solve the problems of LAN(Local Area Network)interconnection and make up for the disadvantages of […]

Although LAN and WAN are two types of networks commonly applied in the daily life, and there are still many people are confused of the difference between LAN and WAN. To remove the doubts for those, Gigalight will […]
