How GPU clusters are connected, from NVLink inside the server to InfiniBand or RoCE fabrics across the data hall, and the MPO fiber links, failure points and checks that keep thousands of GPUs busy.
A practical guide to 400G networks: how 400G Ethernet works, which 400G optics need MPO or LC fiber, the IEEE loss budgets that apply, what breakout can and can’t do, and how to plan cabling that carries over to 800G.
YingFeng Communication is pleased to announce that we will be exhibiting at CIOE 2026 (China International Optoelectronic Exposition) in Shenzhen from September 9–11, 2026.
A beginner-friendly guide to EDFA working principles, C- and L-band use, booster, inline, and preamplifier roles, key specifications, and common selection mistakes.
A beginner-friendly guide to PM fiber, including how it works, what it can and cannot do, common designs, key specifications, and selection checks.
MPO polishing is a geometry-control process, not just surface grinding. See why MT ferrules require staged abrasives and compliant final polishing.
A practical guide to fiber optic adapter types, compatibility, APC/UPC matching, mounting, and procurement checks for FTTH, data center, and telecom projects.
An ODF organizes, protects, terminates, splices, and patches fiber circuits. Learn ODF types, selection criteria, and planning steps for scalable fiber networks.
Fiber optic cables combine a light-carrying glass fiber with protective materials chosen for the installation environment. This guide explains the role of core and cladding, coatings, buffers, strength members, armor and jacket materials—and how they affect cable selection and connectivity planning.
CWDM is a practical way to carry multiple independent data signals over one optical fiber. This simple guide explains wavelengths, CWDM mux/demux devices, key benefits, and the difference between CWDM and DWDM.
