Ⅰ. "Dual-channel" transmission and reception, without interference. Bidirectional over Single Fiber ( BiDi ) means that data transmission and reception can be completed simultaneously within a single optical fiber, unlike ordinary optical fibers which use two separate wires for transmission and reception. The core principle of this technology is the combination of wavelength multiplexing and trans...

As AI large-scale models accelerate their iteration, computing power clusters are moving from "thousands of cards" to "tens of thousands of cards" and "hundreds of thousands of cards." As the "blood vessels" connecting computing power, the internal hierarchical relationships of optical communication are becoming increasingly crucial. However, optical devices, optical modules, and optical engines a...

In popularizing optical modules, SFP and QSFP are often confused. They are actually packaging interface standards from different eras, with the core differences being size, number of channels, and data rate, which determine their application scenarios and adaptation requirements. Simply put, the packaging of an optical module is like a mobile phone charging interface, iterating and upgrading with ...

Push open the door to the data center, and amidst the humming server racks, countless thin optical fibers are carrying massive amounts of data. At the source of these fibers, a component the size of a fingernail — an optical chip—determines the performance ceiling of the entire communication system. Today, we'll discuss the most crucial choice for optical modules: direct-modulated lasers (DML) ver...
