By doubling the number of electrical lanes from 8 to 16, the OSFP-XD offers 1. 6T density with 16 lanes of 100 Gb/s and 3. Support 32-ports in 1RU and 64-ports in 2U chassis. This article explains how this new 1. 6T optical module designed for next-generation data center. transceiver using two, 2-fiber, LC Duplex optical connectors each carrying 4-channels of 200G-PAM4. These modules are available with traditional EML designs as well as innovative TFLN-based technology to meet the evolving demands of modern networks. 6T OSFP optical transceivers, focusing on network protocol, thermal structures, transmission reach, and connector types to help network architects make informed deployment decisions for next-generation AI fabrics.
