The advantage of fiber optic

Fiber optic cable is a cable network that can transmit light. Compared with other types of cable, this cable is more expensive. However, the advantages of fiber optics are numerous; including optical fiber has a more distant range from 550 meters up to hundreds of kilometres, resistant to electromagnetic interference and can transmit data at higher speeds than other cable types.

Fiber optic cables do not carry electrical signals, such as other cables using copper wires. Instead, the signals that represent bits are converted to the form of light. Fiber optic cable consists of two types, known as single mode and multi mode. Single mode cable can reach a longer distance and only send one signal at a time. Multimode cable sends a different signal at the same time, transmit data at different refraction angles at the same time, and transmit data at different refraction shrinkage. Single mode cable to reach hundreds of kilometres while multimode cable is usually only reaches 550 meters or less. Fiber optic cable connector consists of two types of ST connector model of ring shaped and square shaped SC connectors. Use this cable to be adjusted to the type of device you are using because they may be different.

Wireless Evolution

Your phone has been equipped with Wi-Fi? Of course, almost all new telecommunications products output is its Wi-Fi facilities. With this facility you can be accessible to the internet without having to spend your credits; you just need to find a place that it’s Wi-Fi available. 

But do you ever think about the evolution of wireless access technology based on this? This technology is initiated from PSTN or ISDN evolved into a home phone that is still based wire line and then headed to the DSL as a broadband communication anticipation, while wireless technology has evolved from first generation (1G) is analogue to a digital 2G systems to fame with GSM (Global System for Mobile ) evolved into the GPRS (General Packet Radio System), then spreads to the 3G (W-CDMA) with a technology known as UMTS (Universal Mobile Telecommunications System), then to the HSDPA (High Speed Downlink Packet Access) and LTE (Long Term Evolution) . Last one or LTE technology is still evolving toward the target Advance LTE (4G). This is the future of network technology, let's wait how the application.

The advantage of wireless

With computer networks a lot of things we can do, the point we could exchange information to a friend that one to another friend, especially if using internet broadband network, this network can connected to the Internet and our friends and others can send emails one another. And now this is not just the internet, but the technology has grown again with wireless technology.

Many more advantages by using this wireless network technology. You can connect to the internet and search wherever you are. Other advantages of wireless are every day can make browsing the internet with many computers. Without cables, practically and efficiently, wherever you are you can access. Guarantee the provision of services that can be used for 24 hours a day, seven days a week without a pulse telephone. However, any who have the advantage must have a loss, just as this technology is certain to have a negative impact that everyone evens the kids can open the site "weird" at anytime. For it other than we support the development of technology, we must also consider the usefulness of this technology in children, so they do not know who should not be for them to know early in their growth.
