The need of businesses and clients alike for bandwidth is growing rapidly and at an exponential rate. Wired broadband have proven to be stable and satisfying for everyone. And among the players, the fastest-growing technology for wired broadband locally and internationally is still DSL.
DSL or Digital Subscriber Line, is a relatively old technology based on copper telephone wires. Newly arrived technology like cable broadband and fiber optic connectivity though claimed to be faster and reliable still fall behind DSL in terms of consumer sales and business subscribers.
The advances in technology makes it possible to squeeze in extremely high data rates out of the copper-wire infrastructure that exists in nearly every household and business owner. DSL broadbands can offer its subscribers high-end download speeds up to 24Mbps. This is ultimately much better than the single-digit speeds that most DSL customers get nowadays.
Cost still gets the number one deciding factor fiber has not overtaken DSL. It simply costs too much for local and international carriers to deploy. Running fiber over the industry lines towards the home and local businesses costs the carrier to charge hundreds of dollars per subscriber. A hybrid approach of fiber/copper technology still costs far lesser per subscriber line.
The high cost of installing fiber has always slowed the growth of that technology. Thus, DSL will continue to rank high in technological progress over others in the near future. But whether this will stay in the long run remains to be seen.
