Tower Semiconductor Begins Production of 1.6Tbps Optical Transceivers on its Latest Silicon Photonics Platform Addressing the surging demand for faster, high-capacity solutions for AI, cloud computing, and data centers by doubling the speed of today’s 800Gbps high-volume transceivers MIGDAL HAEMEK, Israel, November 19,2024 – Tower Semiconductor (NASDAQ/TASE: TSEM), a leading foundry of high-value analog semiconductor solutions, today announced the start of volume production of 1.6 Tbps silicon photonic products for multiple lead customers based on its latest Silicon Photonics (SiPho) platform.

Tower’s latest platform includes innovations that have helped double data rates relative to its current 800 Gpbs high-volume products. These innovations have been developed in close collaboration with several Tier 1 customers that have designed breakthrough 1.6Tbps products on this enhanced platform and have now begun to order production quantities.

The process supports data rates of 200Gbps per lane, of which eight are built in parallel to achieve the total 1.6Tbps transceiver throughput. This is in contrast to the 100Gbps per lane data rates of existing high-volume silicon photonic technology as used in today’s high-volume 800Gbps products.

“We have recently announced 1.6Tbps optical transceivers based on silicon photonics technology in addition to ramping up our SiPho based 8x100G transceivers. We are very happy to have a strong partner in Tower.

Tower can help innovate and.
