OSFP is a high-speed, high-density, hot-pluggable transceiver module used in data communication applications, targeting speeds of 400G, 800G, and even 1. 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. Unlike the backward-compatible QSFP-DD, OSFP introduces a slightly larger mechanical form to. This specification defines the electrical connectors, electrical signals and power supplies, and mechanical and thermal requirements of the OSFP Module, connector, and cage systems. The OSFP Management interface is described in a separate document: “Common Management Interface Specification. TE's Octal Small Form Factor Pluggable (OSFP) connectors and cable assemblies support aggregate data rates from 200 Gbps up to 1. Designed to support 28G NRZ, 56G PAM4, 112G PAM4, and 224G PAM4. The OSFP-1. 6T-2xDR4 can convert 8x212Gb/s electrical data to 8x212Gb/s optical signals.
