Fiber-optic cables use light rather than electric signals to send data transmissions. These optical light signals travel a fiberglass core and you may hear this technology referred to as fiber optics or optical cabling.
Two categories of fiber-optic cabling are
. Multimode (MM)—This is generally used for shorter distances and is ideal for a campus- sized network. MM also has a larger diameter of optical fiber than SM fiber.
. Single-mode (SM)—This mode is used to span longer distances. SM also allows for a higher data rate than MM and faster data transmission speeds.
Fiber-optic cables may use a subscriber connector (SC), straight tip (ST), or MegaTransfer- Registered Jack (MT-RJ) connector. There are several Layer 2 ethernet protocols that can pass data over fiber-optic cables. Those Layer 2 ethernet standards are 10BASE-FL, 100Base FX, 1000BaseSX, 1000BaseLX, and 1000BaseZX.
All in all, fiber is the best choice for a secure connection over longer distances. Because fiber uses optical light signals for data transmission, it is not as easy to “eavesdrop” on communications as it is with copper cabling using electrical signals. Fiber is not susceptible to EMI and crosstalk, as coaxial and twisted-pair cables are. It also offers the highest maximum speed of the different cable types. You may have already guessed, but fiber is also the most expensive option.
