Overview
The InnoLight 1.6T-DR8 OSFP224 is a pluggable optical transceiver delivering 1.6 Tbps over eight 200G PAM4 electrical and optical channels, with a maximum reach of 500 m over single-mode fiber. Built on InnoLight's in-house silicon-photonics platform, it complies with IEEE 802.3df, the OSFP1600 MSA and CMIS 5.x, and is designed for 1.6T Ethernet, data center and cloud networks.
InnoLight also offers a 1.6T-LPO-DR8 linear-drive variant that removes the retiming DSP for lower power and latency, and an 800G-ZR OSFP coherent module built on an in-house silicon-photonics PIC. The company's 1.6T optics enable 51.2 Tbps of switch throughput in a 1U rack, using the proven 100G SerDes ecosystem with a 200G optical platform.
Key Benefits
Low-power LPO option: linear-drive 1.6T reduces power and latency. Silicon photonics: in-house SiPh and coherent engines. Density: 51.2 Tbps switch throughput per 1U.
Applications
1.6T Ethernet AI back-end networks, cloud data center interconnect, low-power LPO links, coherent 800G-ZR DCI.
