There are several types of QSFP transceivers available, including QSFP28, QSFP56, QSFP-DD (Double Density), and QSFP-DD800 (800 Gbps). Each type has different speed, distance, and power consumption characteristics, and is designed to meet specific application requirements.

QSFP transceivers typically use a variety of optical and electrical interfaces, including Ethernet, InfiniBand, Fiber Channel, and SAS (Serial Attached SCSI). They can be connected to various types of cables, such as copper twinaxial cables, multimode fiber optic cables, and single-mode fiber optic cables.
