Which component, described as Quad (SFP) or QSFP Transceiver, is used for data communication applications?

• A. Quad (SFP) or QSFP Transceiver
• B. Quality of Service
• C. Power over Ethernet
• D. Ransomware

Answer: (A)

Quad (SFP) or QSFP transceivers are physical-layer networking modules that enable data exchange between devices. They are hot-swappable interfaces that sit in switches, routers, or servers and convert electrical signals into optical signals (for fiber) or electrical signals (in some copper variants), providing the hardware path for data communication. The “quad” idea means multiple lanes are bundled together to raise throughput—QSFP parts carry four lanes, which lets you achieve high speeds such as 40 Gbps with QSFP+ or around 100 Gbps with QSFP28. This makes them ideal for data communication applications in data centers and enterprise networks, where fast, scalable links between devices are essential. By contrast, Quality of Service, Power over Ethernet, and ransomware refer to policy, power-delivery, and malware concepts, not to the physical transceiver used for data communication.
