Small optical fiber with building optical cable

The utility model relates to a small-scale optical fiber ribbon building optical cable suitable for the signal transmission among buildings, which comprises an optical fiber ribbon 1, two nonmetal reinforcing parts arranged at both sides of the optical fiber ribbon, and a peripheral enwrapping jacket 3. The optical fiber ribbon is formed by overlapping and combining at least one optical fiber ribbon. The small-scale optical fiber ribbon building optical cable directly utilizes an external diameter optical fiber ribbon as an optical communication unit, which replaces the original optical fiber loose tube to ensure the entire cable to have better superiority, the nonmetal access optical fiber of the optical fiber ribbon adopts optical fiber ribbon or optical fiber ribbon overlapping method, thereby, the intensity of the optical fiber is high, the size of the optical cable is small, and the bending resistance performance is superior. Simultaneously, because two nonmetal reinforcing parts are used, the optical ca
