40G QSFP+ optical modules are mainly divided into three types: QSFP+ 40G SR4, QSFP+ 40G LR4 and QSFP 40G PSM4, and their transmission rates are all 40G. QSFP+ 40G SR4 optical module QSFP+ 40G SR4 optical modules are often used with MPO/MTP connectors to connect to multi-mode optical fibers. The working wavelength is 850nm, and […]
Do you know how the fiber optic cable model is named? GM stands for mobile optical cables for communication, GJ stands for optical cables for communication rooms (offices), GS stands for optical cables for communication equipment, and F stands for non-metallic strengthening members. What is the color spectrum of fiber optic cables? The naming method […]
What is the wireless router network protocol? It is one of the first generation of wireless LAN standards. IEEE 802.11 stipulates that wireless local area networks operate in the 2.4GHz band, which is defined as a spread-spectrum use band by the Global Radio Regulations Organization. The wireless router network protocol refers to some specifications for […]
LightCounting, an optical communications market research organization, pointed out that by 2025, 800G Ethernet optical modules will dominate this market. LightCounting pointed out that the world’s top 5 cloud vendors, Alibaba, Amazon, Facebook, Google, and Microsoft, will spend US$1.4 billion on Ethernet optical modules in 2020, and their spending will increase to more than US$3 […]
Single-mode fiber (SingleModeFiber): The central glass core is very thin (the core diameter is generally 9 or 10μm), and only one mode of fiber can be transmitted. Single-mode fiber has very small inter-mode dispersion and is suitable for long-distance communication, but it also has material dispersion and waveguide dispersion. In this way, single-mode fiber has […]
Not long ago, Hubei Province held a science and technology conference. An exciting news from Wuhan Research Institute of Posts and Telecommunications, the laboratory of the Institute once again set the world record for optical transmission, reaching 400T per second. This means that an optical fiber with the thickness of a hair can accommodate 4.8 […]
