Wired
Interface: Interface ports to connect pieces of equipment. USB (Universal Serial Bus) has become the most popular wired interface to connect peripherals. USB 2.0 supports speeds up to 480 Mbit/s (USB 1: 12 Mbit/s). The interface FireWire is also known as the IEEE 1394 standard. Enhanced IDE (EIDE)is sometimes referred to as Fast ATA, Fast IDE or ATA-2.
Fiber
Host interface: Interface that enables a host controller to communicate with a driver.
PCI Express
Maximum data transfer rate: The maximum speed with which data can be transmitted from one device to another.

Fiber optic connector: This terminates the end of an optical fiber, and enables quicker connection and disconnection than splicing. The connectors mechanically couple and align the cores of fibers so light can pass. Better connectors lose very little light due to reflection or misalignment of the fibers. In all there have been about 100 types of optic fiber connectors produced.
SFP, SFP+, SFP28
Compliance certificates: Indicates which regulatory, safety, and environmental standards the product complies with, as verified by recognized authorities or certification bodies.
