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. Good controls encourage efficiency, compliance with laws, regulations and university policies, and seek to eliminate fraud and abuse. Some everyday internal control procedures include:
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.
Fiber optic cable connectors and the equipment needed to install them are still more expensive than their copper counterparts. Single Mode cable is a single stand (most applications use 2 fibers) of glass fiber with a diameter of 8.3 to 10 microns that has one mode of transmission. Single Mode Fiber with a relatively narrow diameter, through which only one mode will propagate typically 1310 or 1550nm.
