Cisco OSFP 800G Riding Heat Sink Transceiver Modules Data Sheet

Riding heat sink OSFP 800G provides connectivity for Network Interface Cards (NIC) and liquid cooled switches and routers used in AI front-end and back-end networks with reaches up to 500m.

Product overview

Cisco^® OSFP Riding Heat Sink (RHS) 800G transceiver modules provide 800 Gigabit Ethernet (GE), 2x 400GE, 4x 200GE, and 8x 100GE connectivity options, complying with the Octal Small Form Factor Pluggable (OSFP) Multi Source Agreement (MSA) for pluggable transceivers. These modules are primarily used in Network Interface Cards (NIC) with OSFP-RHS ports and can also be used in liquid cooled switches and routers. Cisco OSFP 800G RHS modules are used in AI applications for both front-end and back-end networks as well as other data center applications. OSFP VR8 reach up to 50m over parallel Multi-Mode Fiber (MMF) and OSFP DR8 reache up to 500m over parallel Single-Mode Fiber (SMF). The modules comply with the OSFP MSA configuration with Riding Heat Sink. They meet the IEEE 800GE requirements along with the flexibility of 400GE, 200GE, and 100GE connectivity options for data centers, high-performance computing networks, enterprise core and distribution layers, and service provider applications.

Prominent feature

OSFPR-800G-VR8

The Cisco OSFPR-800G-VR8 module supports 800GBASE-VR8 as well as 2x 400GBASE-VR4, 4x 200GBASE-VR2, and 8x 100GBASE-VR1 breakouts for links up to 50m (OM4/5). The module has eight pairs of multi-mode fiber with dual MPO-12 APC connectors. It is compliant with IEEE 802.3 800GBASE-VR8 and OSFP MSA module requirements with Riding Heat Sink. Optical signals are carried over eight pairs of parallel lanes, with one wavelength per lane. The optical interface can interoperate with any IEEE-compliant module regardless of the form factor. Forward Error Correction (FEC) is performed on the host platform. The OSFP-800G-VR8 module is field firmware upgradeable, complying with CMIS 5.3 firmware upgradability process. The module is shipped with firmware that does not support VDM but can be upgraded.
