What is a QSFP28 Transceiver?
QSFP28 is an abbreviation for quad small form-factor pluggable 28. The QSFP28 transceiver is intended for use with 100 Gigabit Ethernet, EDR InfiniBand, or 32G Fibre Channel networks. The QSFP28 100G transceiver has four high-speed differential signal channels with data rates ranging from 25 Gbps to 40 Gbps. In the 100G optics market, QSFP28 transceivers are more popular than CFP, CFP2, and CFP4 form factors.
What is a QSFP+ Transceiver?
QSFP+, often known as QSFP, is an abbreviation for quad (4-channel) small form-factor pluggable. QSFP+ optics is yet another tiny, hot-pluggable transceiver used in data transmission. Compared to SFP+, QSFP+ supports 4x10G or 4x14G SFP+ data rates to enable increased bandwidth capabilities. It provides several data rate options for Ethernet, Fibre Channel, InfiniBand, and SONET/SDH technologies.
QSFP+ modules support data rates up to 40 Gbps (Gigabits per second) per channel.
QSFP+ is commonly used for 40 Gigabit Ethernet (40GbE) connections in data centers and high-performance computing environments.
QSFP28 modules support higher data rates, typically up to 100 Gbps per channel.
QSFP28 is used for 100 Gigabit Ethernet (100GbE) connections, providing higher bandwidth and increased speed compared to QSFP+.
