The embodiment of the application provides a flexible optical fiber ribbon and optical cable, and when it can be solved among the correlation technique and bend the optical fiber ribbon along width direction, the resin that is used for connecting optic fibre and fiber connection into optical fiber ribbon suffers destruction easily for optical fiber ribbon has the not good problem of roughness.
Referring to fig. 1 and 2, the present embodiment provides a flexible optical fiber ribbon, which includes a plurality of ribbon groups 1, each ribbon group 1 being disposed in parallel, and each ribbon group 1 including three optical fiber units 2.
The three optical fiber units 2 of the core band group 1 are arranged in parallel, the optical fiber units 2 at two sides comprise one optical fiber 3, and the optical fiber unit 2 at the middle comprises at least one optical fiber 3 which is arranged in parallel and connected.
Two adjacent core band groups 1 are connected by a plurality of first connecting portions 4 intermittently arranged along the length direction of the optical fiber 3, and two adjacent optical fiber units 2 in the core band groups 1 are also connected by a plurality of first connecting portions 4 intermittently arranged along the length direction of the optical fiber 3.
Regard as reference surface A with the plane through the axis of two adjacent optic fibre 3, first connecting portion 4 is including two linkage unit 40 that are located reference surface A top and below respectively, connect through first connecting portion 4, and simultaneously, first connecting portion 4 includes two linkage unit 40, make the coating point on the optic fibre 3 all be two-sided coating state, and then make the optic fibre can be to two directions of lower surface free coiling, solved the uneven phenomenon of bonding area surface coating stress distribution of two optic fibre 3 that the resin single face coating caused effectively, can reduce the potential stress concentration risk of optic fibre area, reduce little curved decay, in order to improve communication transmission performance.
Due to the adoption of the double-sided coating structure, the traction forces of the connecting units 40 in the two directions of the upper surface and the lower surface of the flexible optical fiber ribbon are kept consistent, the flatness of the cross section of the expanded optical fiber ribbon can be ensured to be good, and the optical fiber ribbon is convenient for subsequent batch fusion welding.
Due to the adoption of the double-sided coating structure, the optical fiber ribbon can still be ensured to be in a connection state and not to be easily scattered after the connection unit 40 on one side is in a pulled state and is broken, so that the optical fiber ribbon can be conveniently restored to a straight state for batch termination.
