Overview
HGGenuine (HG Genuine) is a top-10 optical transceiver manufacturer with a full catalog of datacom, PON and 5G transceivers. It is in full production of 400G and 800G modules across all standard form factors, PMDs and protocols, with 1.6T ramping, all built on its in-house silicon-photonics technology.
The 1.6T tier includes 1.6T 2xDR4 OSFP modules in LPO and RTLR variants and 1.6T SR8 linear optics. HGGenuine also demonstrated a single-wavelength 400G silicon-photonics engine with 100 GHz bandwidth, positioned as a building block for 3.2T generations.
For 800G, the portfolio spans short-reach LPO modules (SR4 through 2xFR4 in QSFP112/OSFP/QSFP-DD) supporting Ethernet, InfiniBand, NVLink and PCIe protocols, plus a coherent 800G-ZR QSFP-DD reaching 120 km and a 400G OpenZR+ QSFP-DD reaching 480 km for DCI.
Key Benefits
In-house silicon photonics across 400G/800G/1.6T improves supply and cost; LPO plus DSP and 1/2-DSP options flex power versus reach; coherent 800G-ZR and 400G OpenZR+ cover campus and DCI distances; 1.6T 2xDR4 and SR8 address both single-mode and short-reach AI fabrics.
Applications
AI-cluster and hyperscale datacom interconnect, DCI and campus coherent links, short-reach LPO racks, and 5G/PON access networks.
