Installation costs, the need for special testing equipment and susceptibility to damage are notable disadvantages of using fiber optics. Although fiber optics offers superior throughput speeds for data transmission, its disadvantages often make it unfeasible to implement.Continue Reading
The biggest disadvantage of fiber optics is its cost. In order to replace an existing network and install fiber optics, all networking equipment and cabling must be removed. For many organizations, this represents another significant capital expense after a very large investment in infrastructure and labor has already been made. Network technology – routers, switches and receivers, for example – are more expensive, as is the cost of fiber optic cable itself.
Further, fiber optic cable is much more delicate than regular patch cable. Because it’s made of glass, it crushes when rolled over by chair casters, for instance. Also, fiber optic cable is very unforgiving when stretched and, unlike regular patch cable, causes a great deal of network noise and downtime if not replaced promptly. Even cable in good condition can fuse if just a bit too much light passes through an imperfection in the glass. Called fiber fuse, this cable failure can destroy over a mile of cable at a rate of several yards a second. In addition, technology planners must budget for repairs from wildlife damage, as animals shred exterior and underground trunk lines for nesting materials and food or use it to sharpen claws and teeth.Learn more about Optics & Waves
Commercial optical fiber cables use highly purified glass for their cores, glass or polymers for their cladding, and polyurethane for their jackets. Some optical fiber cables use plastic cores, which are cheaper; however, this type of cable has a higher signal loss and works at shorter ranges than glass. Both types transmit light signals using reflection along the axis of the core.Full Answer >
Infrared waves are dangerous because they can cause burns, skin irritation, dehydration, low blood pressure and eye damage. A form of heat radiation, infrared waves are most dangerous at high levels.Full Answer >
Blue-violet light on the visible light spectrum can cause damage to retina cells, increasing one's risk of developing age-related macular degeneration, explains Essilor. Macular degeneration is an eye condition in which the portion of the retina involved with sharp, central vision deteriorates.Full Answer >
A radio wave is a type of electromagnetic radiation that, with sufficient intensity and duration, can result in serious damage or death to a human. Thermal effects caused by radio waves on the human body are especially dangerous, as radio waves can quickly heat tissues to lethal levels.Full Answer >
