FTTA (Fiber To The Antenna) Solution

• FTTA (Fiber-to-the-antenna) is a wireless site architecture where optical fiber is run all the way up the tower to replace much of what was traditionally completed with heavier coax cabling. Important components such as remote radio units (RRUs) are also positioned at the top of the tower instead of at the base location.
• In a FTTA configuration case, a baseband unit (BBU) situated near the bottom of the tower is connected via a fiber optic antenna and runs to a remote radio head (RRH) positioned near the antennas at the top of the tower. The RRH converts the digital signals to analog, and the short span between RRH and antenna is still completed using traditional coax cabling.

• Perhaps the most obvious advantage of fiber-to-the-antenna stems from the physical content of the cable itself. The smaller diameter and lighter weight allow many fiber optic cables to occupy the same amount of space as a single coax cable. Because cellular towers are naturally subject to the elements, the physical size and properties of optical cabling are much less susceptible to damage from gusts of wind.
• Other advantages of fiber-to-the-antenna technology relate to the shift from analog to digital. Due to signal losses, coax cable limited the distance between the antenna and base station to as low as around 100 meters. Optical cabling can span up to 20 kilometers with minimal losses. This allows for central housing of base stations and other similar efficiencies in architecture.
• FTTA also provides improved energy consumption and signal integrity. Tower amplifiers are no longer required to combat the inherent noise floor of extended coax runs. The cooling of power amplifiers through air conditioning in a traditional base unit is replaced by ambient air cooling of the RRH, which significantly reduces the electrical power consumption of the system.
