Optical module is composed of optoelectronic devices, functional circuits and optical interfaces. The optoelectronic device includes two parts: transmitting and receiving. The transmitting end converts the electrical signal into an optical signal, and after transmitting it through the optical fiber, the receiving end converts the optical signal into an electrical signal. structure The transmitting part […]
Briefly, the program calculates the distribution of fiber modes by solving the overall model. The script program needs to define the refractive index distribution value. Through several lines of program code, read the refractive index value in turn, and interpolate to draw the refractive index function n_f(r) graph. The following is the related graphics of […]

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 […]
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 […]
