800G OSFP transceivers are a hot-pluggable optical module designed for very high bandwidth Ethernet links. The Cisco ® OSFP 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) MSA for pluggable transceivers. The modules comply with the OSFP MSA configuration with integrated closed. 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. 25 Gbps PAM4 per lane, achieving a total bandwidth of 800 Gbps over single-mode fiber. 3, OIF-CMIS and other standards. Both represent significant advancements over previous generations.
