Which transceiver is used for data communication applications and is associated with QSFP Transceiver?

• A. Transceiver Quad (SFP) or QSFP
• B. Transceiver Small Form-factor Pluggable (SFP)
• C. Transceiver GigaBit Interface Converter (GBIC)
• D. Transceiver XFP

Answer: (A)

QSFP modules are designed for high-bandwidth data communication, packing four lanes into a single pluggable transceiver. Because QSFP is literally a quad SFP, describing it as a Transceiver Quad (SFP) or QSFP directly reflects this relationship and shows that the quad-lane family extends the SFP form factor to higher speeds. In practice, data networks use QSFP to scale up throughput (for example, 4x10 Gbps in QSFP+, or 4x25 Gbps in QSFP28), which is why this option is the best match. The other transceivers represent different form factors or older designs not specifically tied to the QSFP concept: SFP is single-lane, GBIC is an older, bulkier format, and XFP is another early high-speed option.
