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.
Application:
Remote base station communication such as RRU/BBU.
Smart substation and CATV outdoor application.
Emergency access to optical fiber communication.
From residence to data center and cabling level.
Feature:
Soft, flexible,easy to lay and splice
Salt-mist proof, humidity proof
Good mechanical and environmental characteristics
Flame retardant characteristics
