Problems solved by technology

[0002] Most of the existing access optical cables adopt the structure of separated optical fiber and sleeve, and the sleeve is filled with ointment. Because the mechanical properties of the separated optical fiber are relatively poor, and the filling of ointment brings inconvenience to the branch connection of the optical cable, and the existing The structure setting of the access optical cable is not reasonable enough, which is not conducive to the construction, laying and operation of the optical cable

Embodiment Construction

[0015] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0016] The first example is figure 1 As shown, it is a central bundle tube type full-dry optical cable, including an outer sheath 5 and a sleeve 3, and 4 tight-sleeved optical fibers 1 are laid inside the sleeve, and a water-blocking yarn 2 for the sleeve is placed. Coating the non-metal reinforcement 4, the non-metal reinforcement is aramid yarn or glass fiber, and the non-metal reinforcement is covered with an outer sheath. The casing is a PBT casing, and the sheath is a LSZH flame-retardant sheath.

[0017] The second example is figure 2 As shown, it is a layer-stranded type full-dry optical cable, which includes 6 sleeves, and 4 tight-sleeved optical fibers 1 are laid in the sleeves, and a water-blocking yarn 2 for the sleeves is placed. The sleeves are stranded on the The outer periphery of the central non-metallic reinforcement 8, two water-blo...

Abstract

The invention relates to a full-dry type access optical cable which comprises an outer sheath and a sleeve. The full-dry type access optical cable is characterized in that tight tube optical fibers and a water blocking piece are laid in the sleeve, and a nonmetal reinforcing piece is arranged outside the sleeve. The full-dry type access optical cable has the advantages that the structure arrangement is simple and reasonable, the mechanical performance is good, the bending performance is high, and the full-dry type access optical cable can be conveniently laid in a corridor; the full-dry type full-medium structure is adopted, the optical cable without factice can be beneficial to divergence continuation, and construction laying, operation and use of the optical cable are facilitated; the loose tube structure of the tight tube optical fibers is adopted, enough buffer space is provided for the tight tube optical fibers, the performance of the cable is improved, divergent optical fibers are effectively protected, access construction is facilitated, and the FTTH direct-to-home requirement is met.

Description

technical field [0001] The invention relates to a fully dry access optical cable which is convenient for divergent connection, and belongs to the technical field of optical communication transmission. Background technique [0002] Most of the existing access optical cables adopt the structure of separated optical fiber and sleeve, and the sleeve is filled with ointment. Because the mechanical properties of the separated optical fiber are relatively poor, and the filling of ointment brings inconvenience to the branch connection of the optical cable, and the existing The structural setting of the access optical cable is not reasonable enough, which is not conducive to the construction, laying and operation of the optical cable. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a fully dry access optical cable with a simple and reasonable structure and convenient branch connection for the shortcomings of the above-men...
