High-capacity fiber optic cables are essential for connecting the 5G base stations. Fiber links make system modifications and future upgrades simpler than would be possible with traditional copper links. The RRU is normally located at the top of a tower, roof, or similar bu lding object and very close to the antenna. On the other end, the. In simple terms, Fiber-to-the-Antenna (FTTA) is a broadband network architecture that uses optical fiber to connect the Remote Radio Head (RRH) to the base station instead of coax cables. Introduction. Cell towers, more formally known as base stations or cell sites, are the cornerstone infrastructure facilitating mobile network communication and, critically, providing access to the Internet for mobile devices. They bridge the gap between radio frequency (RF) signals transmitted by user equipment.
