  • [Advanced Guide] Optical Transceiver Technology Innovations Supporting AI Data Centers (AIDC)

    As large-scale AI clusters and AIDC (AI Data Center) environments become commonplace, the core bottleneck in network engineering has shifted beyond the 'software stack' to 'Physical Signal Integrity' and 'Thermal Management.' This is because in fabrics where tens of thousands of accelerators perform all-to-all communication, even delays of just a few nanoseconds (ns) or link flaps can bring the entire collective computation to a halt. In the previous [Basic] section, GBIC's…

  • [Absolute Basic Guide] Don't I need a GBIC to plug in an optical cable?

    If you work in network engineering or at a data center, there is a question and request you hear most frequently: “We need to connect fiber optic cables to that switch, so please bring a few GBICs.‘ However, when you actually visit the site, you have likely been flustered to find that, in addition to simple optical modules, they use unusual cables with integrated cabling, and the module shapes and cable colors vary widely….
