What makes fiber preferable to copper

Fiber optic cables are the better choice if you need to send a signal over greater distances. Copper cables can only carry signals about meters, while some singlemode fiber optic cables can carry more data up to 25 miles. Fiber optic cable also carries data with less attenuation or signal loss—only about three percent every meters—than copper, which loses over 90 percent over the same distance. Since they are electrical conductors, copper cables are still susceptible to interference and electrical surges.

Fiber is also immune to temperature changes, severe weather and moisture, all of which can hamper the connectivity of copper cable. Plus, fiber does not present a fire hazard like old or worn copper cables can. Able to withstand a pulling force of only around 25 pounds, copper wire is fragile when compared to fiber optic cables.

Fiber, despite being much lighter, can withstand up to pounds of pressure, which is certainly preferable during construction of a local area network LAN. Copper cables also experience corrosion and will eventually have to be replaced after as little as five years. Their performance degrades as they age, even to the point where they lose their signal all together.

Fiber optic cables, on the other hand, are sturdier with fewer parts and can last up to 50 years. Passwords can be used to restrict access to all or parts of the Cisco IOS.
