Which transceiver is large and used for Gigabit media?

• A. Transceiver GigaBit Interface Converter (GBIC)
• B. Transceiver XFP
• C. Transceiver SFP
• D. Transceiver QSFP

Answer: (A)

The size and era of the transceiver matter here. For Gigabit Ethernet, the large form factor that was used in early devices is GBIC—the GigaBit Interface Converter. It was a sizable module that plugged into dedicated slots and offered 1 Gbps connections over fiber or copper. Later, smaller options like SFP supplanted GBIC in many deployments, while XFP is associated with 10 Gigabit speeds and QSFP with multi-lane or higher-speed configurations. Because the question emphasizes a large transceiver used for Gigabit media, GBIC is the best fit.
