Terahop

What Terahop does

TeraHop Pte. Ltd. is a Singapore-headquartered optical connectivity solutions company founded in 2018, operating as the international arm of Zhongji Innolight (a publicly listed Chinese optical module manufacturer on the Shenzhen Stock Exchange). The company specializes in silicon photonics-based optical transceivers spanning data rates from 25G to 1.6T across multiple form factors (SFP28, QSFP28, QSFP-DD, OSFP224, CFP2), with over 12 million cumulative units shipped and demonstrated industry-first capabilities including the 12.8Tbps XPO optical transceiver with integrated liquid cooling, 6.4T pluggable NPO solutions, the first end-to-end PCIe Gen 6 over optics solution (with Marvell), and 64x64/300x300 MEMS-based optical circuit switches. The technology platform integrates silicon photonics with coherent detection (DP-QPSK, DP-16QAM), advanced DSP, and high-density packaging to serve AI data center, mobile fronthaul/midhaul/backhaul, and metro/long-haul coherent transport applications.

The company's go-to-market is enterprise field sales targeting hyperscale AI data center operators and cloud providers, supplemented by co-marketing with key ecosystem partners (Marvell, Nvidia, Corning) and active leadership in three industry-shaping MSAs (XPO MSA, Open CPX MSA, SDM4 MCF MSA) that define next-generation optical interconnect specifications. TeraHop maintains wholly-owned subsidiaries in San Jose (sales and marketing for the US AI/data center market), Saraburi, Thailand (high-volume manufacturing and R&D), and Taoyuan, Taiwan (semiconductor and device engineering), giving the company a globally distributed operating footprint that mitigates US-China geopolitical concentration risk. The business model is hardware sales of optical transceiver modules via a quote-based enterprise engagement model, with revenue not publicly disclosed and direct headcount listed at 11-50 employees (reflecting HQ/specialist staff while manufacturing scale is provided through the Thailand facility and parent company).
