Unpacked some new transceivers this afternoon. That’s 6.4Tbps one-handed!
Four clear plastic cases containing four silver metal optical network transceivers with green pull-tab handles in each plastic case, totaling 16 transceivers. These are QSFP56-DD transceivers for 400Gbps Ethernet.

🔥 BREAKING: Ostinato Turbo does 400Gbps!

It's 1518 byte packets, not 64 byte - much more testing and experimentation is still pending.

But still 400G is BIG!

Nous avons changé chez Hivane deux routeurs Juniper à Telehouse2 + Léon Frot.
De deux MX240/480 nous sommes passés à deux MX204 + QFX5100 en satellite.

Moins encombrants, plus économes et électricité, et plus puissants (400Gbps de capacité de routage): all good ! ✅️

The thing is, optical fiber has a long longevity. Like, the same fiber I defined on a campus wide network 12 years ago that would run only 10gbps at the time can now run 400gbps with different transceivers. A GPU running 24x7 on max does not last longer than 3 years, it depreciates to uselessness.

I started working in communications not quite 30 years ago. 33.6kbps modems were all the rage when I started working in this industry, I remember x2 vs flex 56k. Now I support residential customers with faster than 1Gbps connections, and equipment that I work with has 400Gbps connections.

I’m at @techfieldday.com’s AI Infrastructure Field Day … @broadcom.bsky.social presenting. In two slides, how they do data center–to-DC(-to-DC) networking for large-scale applications and services. Pretty impressive
A product marketer at Broadcom shows a slide with the bandwidth their new chips can handle; 3.2 terabits per port × 36,000 ports ganged together. That’s a lot. Then the same product marketer shows that those 32,000 × 3.2-terabyte collections of switches (that all look like one switch, by the way) can interconnect too for a half million 800Gbps connections, or a million 400Gbps connections. Again: that is a lot.
