Overview
Hisense Broadband is a global optical communications manufacturer with more than 20 years supplying transceivers, active optical cables and access-network terminal devices. Its datacom portfolio spans the 1.6T and 800G tiers used in AI and HPC cluster interconnect.
The 1.6T OSFP DR8 modules run eight optical channels at 106 GBaud over silicon photonics, in both a retimed-transmitter/linear-receiver (RTLR) form at under 21 W and a full-DSP form at under 30 W, both reaching 500 m over single-mode fiber via dual MPO-12/APC connectors.
For the 800G tier, Hisense offers a 2xFR4 module reaching 2 km over single-mode fiber at under 10 W, a DR8 linear pluggable optics (LPO) variant at under 9 W and 500 m, and a VCSEL-based SR8 short-reach module for multimode fiber. The modules align to OIF CEI-224G/EEI-224G and IEEE 802.3dj.
Key Benefits
Sub-21W 1.6T RTLR lowers per-port power in dense AI switches; silicon-photonics DR8 gives 500 m reach at 1.6T; 2 km 800G 2xFR4 covers building-scale links; VCSEL SR8 and DR8 LPO provide low-cost, low-power short-reach options.
Applications
AI and HPC cluster interconnect, GPU scale-out fabrics, hyperscale data-center switch uplinks, and 800G migration paths ahead of 1.6T deployment.
