What Gigalight does

Gigalight is a Shenzhen-based, privately held optical interconnect hardware company founded in 2006 with 501-1,000 employees, operating as an integrated designer, manufacturer, and supplier of active and passive optical devices and subsystems. The company's product portfolio spans pluggable optical transceivers from 10G to 1.6T in both III-V and silicon photonics implementations, NPO/CPO silicon photonics engines, O-Band non-coherent and coherent DWDM modules, DCI BOX subsystems (up to 6.4Tb/s), Active Optical Cables (AOC), Direct Attach Cables (DAC), AWGR-based all-optical switching devices, passive xWDM components and MPO/MTP cabling, SDI video modules, immersion liquid cooling solutions, and optical transceiver testing tools.

The company's technology differentiation rests on seven stated proprietary areas: NRZ modulation for ultra-low latency, Half-DSP/LPO architectures delivering 20-30% power savings, O-Band non-coherent DWDM for cost-efficient medium-reach DCI, 1.6T optical interconnect solutions across pluggable, external light source, and NPO architectures, NPO/CPO silicon photonics engines under 16W, AWGR-based all-optical switching with nanosecond-level latency, and immersion liquid cooling achieving PUE below 1.15. Two utility model patents were granted in 2026 covering silicon photonics O-BAND DWDM and 800G/1.6T/3.2T external light source pluggable modules, with corresponding invention patents under substantive examination.

Gigalight operates a B2B direct sales model with quote-based pricing, no public price list, and 24-hour sales response via live chat, email, and phone. Its primary customer segments are AI data centers (GPU/NPU cluster interconnects) and 5G transport networks, with secondary segments in metro WDM transmission, ultra-HD broadcast/video, and private/campus networks. The company participates in international industry events including ISC 2026 in Hamburg, IBC in the Netherlands, and CIOE in China, and claims active cooperation with global operators, though no specific customer logos are disclosed. Revenue, funding history, ownership structure, and management team are not publicly disclosed in the available source materials.
