* QSFP+ (Quad Small Form-Factor Pluggable Plus): This transceiver type is designed specifically to handle 40Gbps network speeds. QSFP+ connectors are hot-swappable and support various cable types, including fiber optic and copper (DAC). * 10GigE: While a valid network technology, 10GigE only supports up to 10Gbps, not the required 40Gbps. * SFP (Small Form-factor Pluggable): A common transceiver type, but the standard SFP only supports a maximum of 1Gbps. * SFP+ (Enhanced Small Form-factor Pluggable): Supports up to 10Gbps, not sufficient for 40Gbps in this scenario.
