Coherent
Coherent (formerly II-VI and Finisar) builds datacom transceivers from its own lasers up: VCSELs, EMLs, InP CW lasers and silicon photonics. It started revenue shipments of 1.6T transceivers in its fiscal fourth quarter of 2025.
Facts
Source per value- Role Where the company sits in the optics supply chain: pluggable module maker, DSP and chip supplier, laser and component maker, network OEM that sells its own optics, contract manufacturer, optical I/O and co-packaged optics developer, or active electrical cable maker.
- Module maker 2
- Top speed Gb/s Highest module or chip application rate documented in the cited sources, in Gb/s (1600 = 1.6T). A historical catalog or announcement is not proof of today’s maximum or volume shipments.
- 1,600 2
- Speeds Data-center speed grades in the current portfolio, as the company lists them.
- 800G, 1.6T; 3.2T demonstrated (OFC 2026) 3
- 1.6T status Evidence for the 1.6T module or chip: volume/revenue shipping, customer sampling, or public demo/announcement. Blank means no dated status established; inspect the source date.
- Shipping 1
- Form factors Pluggable form factors offered (QSFP28, QSFP56, QSFP112, QSFP-DD, OSFP, OSFP-XD and so on), or the package type for chips and engines.
- OSFP (QSFP-DD versions to follow) 2
- LPO / LRO Offers linear pluggable optics (LPO) or linear receive optics (LRO), or the drivers, TIAs or DSPs built for them.
- Not published
- CPO / optical I/O Offers co-packaged optics, optical engines for CPO, or optical I/O chiplets.
- Not published
- Silicon photonics Identifies silicon photonics in a published product, design or demonstration. This flag does not establish volume shipments.
- Yes 3
