Leveraging 200G/lane silicon photonics and cutting-edge PAM4 technology, our 1. 6T OSFP DR8 modules—available in both Retimer and LPO versions—deliver exceptional performance with low power consumption and up to 500 meters reach over single-mode fiber. This article explains how this new 1. (NYSE: KEYS) today introduces the next generation of its 1. 6T-capable passive copper Direct Attach Cables (DAC), Active Copper. These pluggable optical transceivers conform to standards defined by multi-source agreements (MSAs), such as Small Form Factor Pluggable (SFP), Quad SFP (QSFP), QSFP-Double Density (QSFP-DD), Octal SFP (OSFP), and Common Management Interface Specification (CMIS). 5 Gbps PAM4 per lane for an aggregate data.
