Cables and Connectors
Because the link to a port can be driven either optically or electrically, the term
“fibre” in Fibre Channel refers to either a fiber optic or a copper cable.
■ Optical transmission occurs over both single and multi–mode fibers using both
laser and light emitting diodes (LEDs) for both short (770–850 nm) and long
(1300–1360 nm) wavelengths.
■ Electrical transmissions occur over video coax, miniature coax, twin coax (Twin
Ax), or twisted pair.
TABLE 4-1 lists the cable and connector specifications that the libraries support.
