Material of Data and Optimization of Cables
1816 - Copper wires were first used underground to relay a telegraph; copper is good electric conductor
| 1881 - UTP (Unshielded Twisted Pair) is the most common & inexpensive cable used in LANs (local area networks); used in ethernet & telephone lines. |
1929 - Coaxial cables include a central wire that carries the signal. The wire is protected by braided metal guard, often made of copper. Made using twisted copper wires & plastic polymer (polyethylene) outer jacket.
| 1970 - Fiber optic cables began to have widespread usability in telecommunications. They were able to carry signals greater distance than copper & are now widely used in high-speed internet & telecom as well as data centers as we know them today. Revolutionized the use of purified glass to transmit light signals very fast. |
2002 - Cat 6 is a reliable, fast ethernet cable that has good resistance to cross talk (electromagnetic interference from another set of wires). It is made with 4 pairs of twisted copper wire & protective outer jacket made from materials such as PVC.
Conclusion: Conductive materials have been pushed to their physical limits to most effectively and quickly transfer data over a range of distances. The trend towards longer distances begins to signal the push towards globalization. |

The physicality of these cables begin to have real-world implications on our landscapes as the overlap and connect. Typically fiber optic cables and copper wire-based cables such as Cat 6 form into webbed networks that connect people regionally, nationally, and internationally. This brings our city landscapes to accommodate to the sea of cables formed by these connections. |
