Abstract

The invention belongs to the technical field of communication optical cables, and discloses a compact optical cable. The optical cable comprises an optical unit, a wrapping yarn layer, a central reinforcing member, a water-blocking element and an outer sheath. The plurality of optical units and the plurality of water-blocking elements are arranged in parallel in the axial direction to form an optical unit group, the wrapping yarn layer sleeves the periphery of the optical unit group to form a wire harness group, and the wrapping yarn layer is used for fixing the optical units and the water-blocking elements in the optical unit group; different wire harness groups are distinguished through wrapping yarn layers with different colors; the wire harness group is twisted on the periphery of the central reinforcing member. And the outer sheath is arranged on the outermost layer and is used for tightly sleeving the wire harness group and the central reinforcing piece. According to the optical cable, the production cycle of the optical cable is shortened, the production efficiency of the optical cable is improved, the cable diameter is reduced, the weight of the optical cable is reduced, the structure of the whole optical cable is more compact, and wiring is further facilitated.

Description

technical field [0001] The invention relates to the technical field of communication optical cables, in particular to a compact optical cable. Background technique [0002] The 3G network uses a large number of distributed base station architectures, and the remote radio unit RRU (Remote Radio Unit) and the base band processing unit BBU (Base band Unit) need to be connected by optical fibers. One BBU can support multiple RRUs. [0003] In a 5G network, the baseband processing unit BBU is decomposed into two parts: a distributed unit DU (Distributed Unit) and a centralized unit CU (Centralized Unit). The connection from the active antenna to the DU is the scope covered by the fronthaul. In the initial stage of 5G network construction, the fronthaul is mainly driven by optical fiber direct drive. Each active antenna and DU use optical fiber point-to-point direct connection networking. The construction, maintenance and management of this method are relatively simple, and can ...
