What are internal controls and why are they important? Internal controls are the procedures put in place to help achieve the objectives of the university relating to financial, strategic, and academic initiatives.

Standard Fiber Optic Cable. Sealed with a Teflon jacket over a stainless steel sheath, Williamson's standard fiber optic cables are available in lengths of 3 - 30 feet (1-9 meters). Cable diameter is .25 in. (6.5mm) with a lens assembly that is 3.05 in. long x 0.5 diameter (77mm x 14mm). They are suitable for most general purpose applications.
So fiber optic cable is used to extend the network, from 2000 meters up to 120 km. A fiber optic media converter has two interfaces. One interface is the local electronic interface, may it be a RJ45 Ethernet, or RS-232 serial data interface. The other interface is usually a duplex fiber interface with ST, SC, or LC connectors. One of the optic port is the optical transmitter.
