Problem regarding Networking and Internet.

DSL means Digital Subscriber Line. It’s a device to transfer data from one device to another device. It has a limitation of data transmission. Normally any DSL can 6Mbps rates of data transmit.  

It has a supporting technology. Copper and fiber can not support DSL. Copper has specific supporting device to data transmit and Fiber also supporting device like fiber channel, Tj box, Fiber connector, Router etc.

Fiber also more capacity corporately  any DSL modem. DSL can not support such high rate of data transmission. Its only used in short distance. On the other hand Fiber used in long geographical area.

Both technologies has similar feature but there have  technical and functional difference.

Thanks

DSL was originally known as Digital Subscriber Loop that was later changed to Digital Subscriber Line. It is a line of technologies that offer internet access using the local telephone network. The theory behind this form of communication can be tracked way back in a 1948 seminal paper created by Claude Shannon entitled “A Mathematical Theory of Communication”. This caused for an early patent to be filed in 1979 to use the local telephone wires for both data terminals and voice phones that were linked using a digital data carrier system on to a remote computer.

In a consumer DSL service, the bit rate varies from 256 kbps up to 40 Mbps. This is the downstream or the flow is in the direction of the customer. Fiber optics is mainly used in broadband internet service and is widely being used nowadays. Connection is fast in this type of connection because it uses stream of lights to transfer data between both terminals. Copper can’t be used in DSL connection because it generates more heat than fiber optics and it has more resistance making the connection very slow.
