OSFP is a high-speed, high-density, hot-pluggable transceiver module used in data communication applications, targeting speeds of 400G, 800G, and even 1.6TB.
The OSFP 1.6T LPO transceivers (500m, SMF) are also compliant with OSFP MSA, IEEE 802.3, OIF-CMIS, and RoHS standards, and are compatible with OSFP IHS connectors and
Octal Small Form-factor Pluggable (OSFP) solution that fits into high-density switch and router client ports for optical interconnect links. Powered by Greylock and Delphi DSP ASICs, and silicon
OSFP was among the first form factors to support native 800G, making it a key enabler for ultra-high-speed deployments. It is fully compliant with 400ZR and 800ZR, ensuring energy-efficient, high
Below sub-sections illustrate block diagrams for a sampling of optical physical medium dependent sublayers (PMDs) that can be realized in an OSFP form factor. These block diagrams are meant to
Amphenol OSFP interconnect system has 60 contacts per port, with a 0.6mm contact pitch and 8 high speed channels. The OSFP footprint is optimized for signal integrity performance

Cisco QSFP-DD and OSFP 800G coherent optical modules are supported on Cisco switches and routers. For more details, refer to the Cisco Transceiver Modules Compatibility Matrix.
OSFP optical modules include 400G SR8/DR8 and 800G DR8 /FR8 variants. They deliver low latency, high bandwidth, and built-in FEC for error-free transmission up to 10km.
OSFP connectors are slightly larger than QSFP-DD connectors but offer increased thermal performance and signal integrity at high data rates. The OSFP system supports higher-power modules and is
