Increasing Demand for High Bandwidth Connectivity

With increasing smartphone and internet usage, bandwidth demand has been growing exponentially in recent years. People no longer just access basic internet on their phones and computers - they now stream high-definition videos, make video calls, engage in online gaming, and more. This boom in bandwidth-hungry applications has drawn attention to technologies that can help expand network capacity to meet future needs. As a result, many enterprises and data center owners are considering the installation of dark fiber networks within and between their facilities to ensure high-speed connectivity now and in the future. Dark fiber offers literally unlimited bandwidth potential since fiber cables are not put to active use until laser transmitters and receivers are installed on either side. The upfront cost of laying dark fiber is also offset by its future-proofing ability and long lifespan of over 25 years.

For instance, Colt Technology Services, a telecommunications company, offers a dark fiber network to around 1,000 data centers in Europe and Asia. The company’s dark fiber provides businesses with maximum levels of flexibility and control to support virtually unlimited bandwidth.
