Further, the diameter of the tight-buffered optical fiber was 0.6 mm.
Further, the diameter of the optical fiber in the tight-buffered optical fiber was 124.9. + -. 0.2. mu.m.
Further, the reinforcing member is an aramid fiber reinforced optical cable reinforcing core.
Further, the suspension wire is made of water-blocking glass fiber yarn.
Further, the outer sheath is made of flame-retardant TPU sheath material.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model provides a pair of full medium self-supporting butterfly-shaped optical cable, including tight set optic fibre, tight set optic fibre sets up in the loose tube, is equipped with the yarn that blocks water between the outer wall of tight set optic fibre and the loose intraductal wall of cover, and the loose tube sets up in the oversheath, still is equipped with two reinforcements in the oversheath, and two reinforcements set up respectively in the both ends of loose tube, and the connecting piece is passed through to the one end of oversheath and the suspension wire is connected, the central reinforcement of suspension wire, reinforcement and reinforcement, loose tube's the centre of a circle are located a straight line. The structure is compact, the size is reasonable, and the production cost is greatly reduced.
The diameter of the tight-buffered optical fiber is 0.6mm, the size is small, the cost is low, and the construction is easy. The diameter of the optical fiber in the tight-buffered optical fiber is 124.9 +/-0.2 microns, so that the concentricity error of the optical fiber and the ferrule is smaller, the fiber core is more centered, the insertion loss of the connector assembly is smaller, and the index data is more stable.
