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.
Based on the speed of light alone (299,792,458 meters/second), there is a latency of 3.33 microseconds (0.000001 of a second) for every kilometre of path covered. Light travels slower in a cable which means the latency of light travelling in a fibre optic cable is around 4.9 microseconds per kilometre.
