For longer distances, fiber-optic cables are typically installed by hanging them between poles (aerial), laying them on the seabed (submarine), or burying them in the ground (underground). While buried cables offer aesthetic appeal, the aerial fiber optic cable remains the workhorse of long-distance transmission and rapid network rollouts. This comprehensive guide explores everything you need to know about overhead fiber solutions. Aerial installation is generally much less costly than underground construction also. Aerial cables should be installed "in a neat and workmanlike manner;" which can be interpreted as "what is correctly done also looks. Fibre-optic Link Around the Globe (FLAG) is a 28,000-kilometre-long (17,398 mi; 15,119 nmi) fibre optic mostly- submarine communications cable that connects the United Kingdom, Japan, India, and many places in between.
