Mixx's SxC connector terminates 24,576 fibers in one rack unit, delivering 4x the density of MMC-VSFF while using the same 64-fiber core for...

AI scaling turns photonics into a system requirement, not an option, as bandwidth, power, and packaging constraints force nuanced use of pluggables, extended copper in megawatt racks, and narrow CPO deployments in vertically integrated switches.

Google's TPU cable introduces two-core fiber on its Taiwan-Philippines branches in 2026, building on a 410.5 Tbit/s 7-core trial over 140 km with...

In scale-up optics, connector and silicon photonics platform losses consume the majority of the link budget (roughly 60/40 split), leaving only a...

Optical Circuit Switching (OCS) slashes energy use for high-port switching from ~3000 W in EPS to ~100 W, cutting overall consumption to 0.2%—a 30X...

ProLabs' new QSFP-DD coherent transceivers extend 400G and 800G transmission across up to 30 repeater hops, underscoring pluggables' growing viability for multi-hop metro and regional links where dedicated transponders were previously required.
