Why each option
For 40 Gigabit Ethernet (40GbE) network connectivity in a server environment, the QSFP+ (Quad Small Form-Factor Pluggable Plus) transceiver is the industry-standard connector.
SFP+ (Small Form-Factor Pluggable Plus) transceivers are primarily used for 10 Gigabit Ethernet (10GbE) connections, not 40GbE.
GBIC (Gigabit Interface Converter) is an older and larger form factor used for 1 Gigabit Ethernet (1GbE) connections.
SFP (Small Form-Factor Pluggable) transceivers are generally used for 1 Gigabit Ethernet (1GbE) connections.
QSFP+ (Quad Small Form-Factor Pluggable Plus) is the standard form factor designed for 40 Gigabit Ethernet (40GbE) networking. QSFP+ transceivers aggregate four independent 10Gbps data lanes into a single module, enabling a total throughput of 40Gbps, making it the correct choice for 40Gb network connectivity.
