I have written the report you requested November 22nd investigating the possibility of our Museum’s implementation of Fiber Optic cabling. It discusses the issues with installing copper lines and compares the benefits of each service. It then evaluates Fiber Optics presenting a recommendation based on that evaluation.

Problem: Copper Networks are Outdated Technology

John Tyndall is often credited as the father of fiber optics due to his research on the transmission of light in the 1870’s. After the invention of the photophone however, Fiber Optics hit a standstill for nearly a century. It wasn’t until the 1970’s when the US Military began to use fiber optic technology and since then it has been expanding exponentially in both performance and reduction of cost.

Regardless of where you look today you see new businesses installing fiber optic cable. Businesses around the world want the fastest data transmission rates that the world can offer. Despite the recent advancements in unshielded-twisted-pair cable, fiber optics continues to expand at a faster rate. Investigation shows that depending on the situation, either technology can be ideal. It is my belief that fiber fits our current situation better and the details of this is explained below.

Establishing Criteria for our Network: Cost

One of the biggest factors when installing a network has always been cost. It is common knowledge that copper cabling is cheaper than their fiber optic counterparts because fiber optics give better performance. To get into such a mind set however, would be narrow minded. In certain situations, an all-fiber Local Area Network is actually cheaper than a copper network.

Copper Local Area Network layouts are similar to the initial telephone system designs. The Local...
