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 communication. An optical fiber junction box. The yellow cables are single mode fibers; the orange and blue cables are multi-mode fibers: 62.5/125 Âµm OM1 and 50/125 Âµm OM3 fibers, respectively. Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber.
