Fibre Channel is a high-speed network technology that is mainly used for storage area networks (SANs). It provides reliable and secure data transfer between servers and storage devices, such as disk arrays, tape libraries, and optical jukeboxes. It uses protocols such as SCSI, FCP, and FICON to transport data over optical fiber or copper cables678 Fibre Channel transceivers are devices that convert electrical signals to optical signals and vice versa, and allow Fibre Channel devices to communicate over different media types and distances. They are usually pluggable modules that fit into standard ports on Fibre Channel switches, adapters, and storage devices. They have different specifications and standards, such as SFP, SFP+, QSFP, and CFP, depending on the data rate, wavelength, and cable type they support.
8 Gbps transceivers are Fibre Channel transceivers that support a data rate of 8 gigabits per second, which is also known as Fibre Channel-8G or 8GFC. They are typically SFP+ modules that use 850 nm wavelength and multimode fiber for short-reach applications, or 1310 nm wavelength and single-mode fiber for long-reach applications. They can support cable distances up to 10 km or 40 km, depending on the fiber type and quality.
