While fiber optic cables have many advantages, fragility is one of their biggest limitations. Generally made of glass, fiber optic cables are much lighter and thinner than metallic wiring, making them widely susceptible to damage. Radiation or exposure to chemicals can damage a fiber optic network. Its fragile cables can be cut easily during buildi. Fiber TerminationBox (FTB) or Optical Terminal Box (OTB) is a distribution box speciallydesigned for fiber cable management in FTTH applications. Its core use is toterminate fiber optic cables and connect the cable's core and pigtail. A fiberpigtail is a short, single, tight-buffered optical fiber that has an opticalconnector pre-installed on one e. Wall-mounted and Rack-mounted FiberTermination Boxes can be categorized into rack-mounted and wall-mounted boxesbased on their designs. The latter is generally sealed and hangs on the wall,while the former has a rear and front door with a side rail attached directlyto the rack of the server. Wall-mountedFTB is largely meant for direct connections.
