iPronics tests silicon photonics switch with 1.6T datacenter signals

Quantum ZeitgeistSeptember 22, 20263 min read

AI datacenters are driving a rapid transition toward higher-capacity optical interconnects, as transceivers move to 1.6 Tb/s with 200G per optical lane. iPronics, together with Lumentum, tested whether a programmable silicon-photonics Optical Circuit Switch can be inserted into a 200G-per-lane link without significantly compromising signal integrity.

Artificial intelligence datacenters are demanding increasingly high-capacity optical connections, and iPronics, a Valencia-based developer of programmable photonic circuits, has demonstrated a key component for scaling that infrastructure, the company says. Working with Lumentum, the company tested its silicon-photonics Optical Circuit Switch with 1.6 terabit-per-second signals, a rate achieved with 200G per optical lane.…
