> Twenty-four 200 gigabit (Gb) Ethernet ports are integrated into every Intel Gaudi 3 accelerator How much does a single 200Gbit active (or inactive) fiber cable cost? Probably thousands of dollars.. making even the cabling for each card Very Expensive. Nevermind the network switches themselves.. Simultaneously impressive and disappointing.

If you're going fiber instead of twinax it's another order of magnitude and a bit for trancievers, but cables are pretty cheap still. You seem to be loading negative energy into this release from the get-go

  You're going to need a lot more than 2 meters... It's probably AOC (Active-Optical Fiber Cable), they're pricey even for 40Gbit, at DC lengths.

    2 meters is enough to connect a server to a leaf ToR switch. Now, connecting the leaf switches to the spine is a different story...

What do you mean by active vs inactive fiber cable? I tried to Google about this distinction, but I couldn't find anything helpful.

  My off-the-cuff take: AOC's are a specific kind of fiber optic cable, typically used in data center applications for 100Gbit+ connections. The alternate types of fiber are typically referred to as passive fiber cables, e.g. simplex or duplex, single-mode (single fiber strands, usually in a yellow jacket) or multi-mode (multiple fiber strands, usually in an orange jacket). Each type of passive fiber cable has specific applications and requires matching transceivers, whereas AOCs are self-contained with the transceivers pre-terminated on. If you search for "AOC Fiber", lots of resources will pop up. FS.com is one helpful resource. https://community.fs.com/article/active-optical-cable-aoc-rising-star-of-telecommunications-datacom-transceiver-markets.html https://community.fs.com/article/active-optical-cable-aoc-ri... > Active optical cable (AOC) can be defined as an optical fiber jumper cable terminated with optical transceivers on both ends. It uses electrical-to-optical conversion on the cable ends to improve speed and distance performance of the cable without sacrificing compatibility with standard electrical interfaces.
