FalconX Multi-Wavelength ELSFP Laser

Xscape Photonics is a California-based startup (Santa Clara, with a second location in Fort Lee, New Jersey) that develops custom silicon photonics to remove bandwidth bottlenecks in AI clusters. The company was founded by Vivek Raghunathan with Columbia University professors Michal Lipson and Keren Bergman, and focuses on a laser architecture for optical interconnects.

Its FalconX product is described as a fully redundant external laser small-form-factor pluggable (ELSFP) that emits eight wavelengths and delivers more than 1 W of optical power from one module. It is aimed at scale-up and scale-out links in AI data centers, with sampling planned for hyperscaler-type buyers. A second product, EagleX, is listed on the company site.

• Eight-wavelength output: the FalconX ELSFP emits eight wavelengths for optical data transmission.
• High optical power: more than 1 W from a single pluggable module.
• Fully redundant design: built-in redundancy keeps links running when a laser fails.
• Pluggable form factor: external laser small-form-factor pluggable for data center switches and accelerators.
• Custom silicon photonics: the company develops tailored photonics for AI cluster connectivity.

Optical transceiver and co-packaged optics makers can integrate the laser module into AI switch designs. Data center operators building GPU clusters in Vietnam and ASEAN can evaluate it through hardware partners for high-bandwidth scale-out networks.

A single pluggable module supplies more than 1 W of optical power across eight wavelengths, which Xscape states can support multi-terabit-per-second bandwidth. Built-in redundancy and more reliable components reduce the impact of laser failures on AI links. The pluggable form factor targets both scale-up and scale-out connectivity.

AI clusters are limited by interconnect bandwidth and power, which drives demand for optical links with external laser sources. Vietnamese and Southeast Asian data center and AI infrastructure builders will meet these components mainly through global switch and transceiver vendors.
