Optical Transceivers

Small Form-Factor Pluggable (SFP, also known as mini-GBIC) is a hot-pluggable network interface transceiver standardized under INF-8074i / SFF-8074. Operating across a single electrical channel, it supports data rates up to 1.25 Gbps for Gigabit Ethernet and 4.25 Gbps for Fibre Channel using duplex LC optical interfaces or RJ45 copper.

Enhanced Small Form-Factor Pluggable (SFP+) is a standardized 10 Gbps transceiver form factor defined by SFF-8431 and SFF-8432. Retaining the physical dimensions of standard SFP, it supports 10 Gigabit Ethernet (10GbE), 8G/16G Fibre Channel, and OTU2 over a single 10.3125 Gbps serial electrical lane.

Quad Small Form-Factor Pluggable Double Density (QSFP-DD) is a high-speed transceiver form factor defined by the QSFP-DD MSA and SFF-TA-1002. It incorporates an 8-lane electrical interface via an extra row of electrical contacts, delivering 400 Gbps (8x50G PAM4) and 800 Gbps (8x100G PAM4) while maintaining mechanical backward compatibility with QSFP28 and QSFP+.
