These dormant fibers are like untapped potential waiting to be harnessed, offering countless opportunities for expanding and enhancing data network capabilities. With the rapid growth of data-intensive applications and the insatiable demand for high-speed internet, it has emerged as a strategic asset for internet service providers (ISPs) like 123NET.
