Which transceiver is a mini-GBIC and is associated with the Small Form-factor Pluggable (SFP) standard?

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

Answer: (A)

A mini-GBIC is the small plug-in module defined by the SFP family; it is the SFP transceiver. The idea behind SFP was to replace the larger GBIC with a compact, hot-swappable module that still provides the electrical-to-optical interface for fiber or copper links. That makes the SFP transceiver the direct embodiment of a mini-GBIC. The other options point to different form factors: QSFP is a multi-lane, higher-throughput version; GBIC is the original larger module; XFP is another older 10G form factor.
