Which transceiver type is typically used for 10 Gigabit Ethernet networks?

• A. Transceiver XFP
• B. Transceiver SFP
• C. Transceiver GBIC
• D. Transceiver QSFP

Answer: (A)

For a 10 Gigabit Ethernet link, the transceiver form factor that historically fits the speed best is the XFP module. XFP was designed specifically for 10G, providing the electrical-to-optical interface at that data rate and supporting common 10GBASE wavelengths. It was widely deployed in early 10G networks, making it the typical 10G choice in many deployments. In contrast, the GBIC is an older, larger module used across various speeds and was largely superseded by the smaller SFP family. The standard SFP is geared to 1 Gigabit Ethernet, with SFP+ as the 10G evolution—but the option without the plus specifies the older 1G form factor. QSFP focuses on higher-density, multi-lane bridges for 40G or 100G, not the common single-2-port 10G link. So the XFP best matches the classic 10G transceiver for a typical 10G network.
