Also referring to Fig. 1 and Fig. 2, the present embodiment provides a kind of easily separated optical cable 100 of self-adhesion, including multigroup self-adhesion easily divides
From fibre bundle 110 and oversheath 120, oversheath 120 has inner chamber 121, and oversheath 120 is extruded in the easily separated optical fiber of multigroup self-adhesion
Outside beam 110, the easily separated fibre bundle 110 of multigroup self-adhesion is set to be arranged side by side in inner chamber 121.
Referring to Fig. 3, in the present embodiment, the easily separated fibre bundle 110 of every group of self-adhesion includes fibre core 111 and is coated on fibre core
The coat 112 of 111 outer surface.
Fibre core 111 includes the more optical fiber 113 being arranged side by side, and the diameter of every optical fiber 113 is about 250 μm, and optical fiber 113 selects
With G.657A2 optical fiber.
Due to cable manufactures, turn occasion is more in the indoor comprehensive wiring such as commercial office building, such as wall column turning with
Line terminal equipment etc..G.657A2 its bending property of optical fiber is excellent, is adapted to the full wave transmission systems of 1260nm~1625nm
System, it is very small in the bending annex decay of long wavelength's section, even if bending radius also only has in 7.5mm, 1625nm window added losses
0.8dB.High bandwidth, low decay and the FTTX short-distance and medium-distance that single-mode fiber can be given full play to transmit the advantages that all suitable.
The outer surface i.e. coat 112 that coat 112 is coated on fibre core 111 is coated on positioned at the outermost of fibre core 111
The surface of the close coat 112 of optical fiber 113, for being protected to fibre core 111 and realizing the isolation between multigroup fibre bundle.
Using the set-up mode of coat 112, in the production of fibre bundle, multiple optical fiber 113 are axially closed side by side along it
