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 connectors are unique. Fiber cables transmit pulses of light instead of electrical signals, so the terminations must be much more precise. Instead of merely allowing pins to make metal-to-metal contact, fiber optic connectors must align microscopic glass fibers perfectly in order to allow for communication. While there are many different types of fiber connectors, they share similar design characteristics. Simplex vs. duplex: Simplex means 1 connector per end while duplex means 2 connectors per end. There are three major components of a fiber connector: the ferrule, the connector body, and the coupling mechanism.
