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.Know More
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
One of the disadvantages of radio waves is that they cannot transmit a lot of data simultaneously because they're low frequency. In addition, continued exposure to large amounts of radio waves can cause health disorders like leukemia and cancer. Despite these setbacks, technicians have effectively achieved enormous breakthroughs. For example, astronauts use radio waves to transmit information from space to Earth and vice versa.Full Answer >
The chief danger of radiation is the damage it can cause to living cells. Radiation can damage the DNA inside a cell's nucleus, and if the DNA becomes sufficiently damaged, the cell can become cancerous. Exposure to high amounts of radiation, or lower amounts over a long period of time, can significantly increase the risk of developing cancer.Full Answer >
Instant messaging is convenient and more cost effective than traditional forms of communication; however, instant messaging can pose a security risk, allowing viruses to damage the computer and the network. Additionally, instant messaging has the potential to compromise the security of sensitive information.Full Answer >
The resources and expertise needed to fix fiber cabling have not yet spread out extensively in most parts of the world. This makes the cost of installation costly. It usually involves a great deal of expert skills, tools and complex processes.Full Answer >
