The OSFP optical transceiver module is designed for 400GBASE Ethernet throughput up to 500m link lengths over OS2 singlemode fiber (SMF) using a wavelength of 1310nm via MTP/MPO-12 APC connectors. This transceiver is compliant with CMIS 5. The built-in digital. Enter OSFP (Octal Small Form Factor Pluggable) — an open standard designed to deliver scalable, thermally optimized, and high-density optical connectivity for hyperscale, cloud, and AI-driven environments. It features 8 independent electrical input/output channels, each operating at speeds up to 106. These devices were developed to address the need for higher bandwidth and efficiency in contemporary networking. Among the different optical standards that enable 400G, the OSFP 400G DR4 stands out for its parallel single-mode architecture, moderate reach, and high density.
