Coherent Showcases 1.6T–3.2T Pluggables and XPO Path to 12.8T at OFC 2026

Overview

• Live demonstrations span 1.6T pluggables, 3.2T 400G‑per‑lane links, and a new multi‑lane XPO form factor targeting 12.8T and beyond.
• CPO technologies on display include a 6.4T socketed silicon photonics design with an external laser source, a multimode VCSEL socketed CPO, and an InP‑on‑silicon 400G‑per‑lane modulator.
• Multiple 1.6T OSFP transceivers combine silicon photonics PICs, high‑power InP CW lasers, 200G InP EMLs, and 200G GaAs VCSELs with DSPs from three vendors.
• Coherent highlights a broadened InP portfolio and confirms a ramp to 6‑inch wafer production in Järfälla, Sherman, and Zürich to bolster next‑generation optical engines.
• The company joins the XPO MSA and helps found the Open CPX MSA, participates in OIF multi‑vendor interoperability demos, and shows system‑efficiency features including four‑rail transport in 1RU and a thermo‑electric generator.
