Abstract

The invention relates to an optical cable for connecting 3G equipment, which comprises a plurality of sub-unit cables (1), a loosened sleeve (2), a reinforcer layer (3) and an outer sheath (4), wherein the plurality of sub-unit cables are directly arranged into the loosened sleeve (2); reinforcers are coated on the circumference of the loosened sleeve; the outside of the reinforcer layer is provided with the outer sheath; and the whole cable has a full-dry structure. The optical cable for connecting the 3G equipment is taken as a jumper for optical communication equipment in a building and outdoor optical terminals on the roof and so on, has the advantages of full-dry structure, good bending property, fire retardation, lightning protection, handiness, large transmission capacity, good confidentiality and so on; joints can be arranged on both ends of the cable in advance for convenient connection; and the invention is an optical cable for connecting the equipment aiming at 3G optical-fiber network construction.

Description

technical field [0001] The invention relates to an optical cable for a communication network, especially suitable for the connection of 3G optical network equipment, and is an optical cable aimed at the construction of the 3G communication network. Background technique [0002] In the construction of a 3G network, the network base stations and the wireless access network need to be connected through optical cables. In addition to the radio access network, the 3G network also has a huge core network. To connect the core network with support nodes such as radio network controllers and mobile switching centers, optical cables are also required. With the practical application of 3G technology, more and more 3G equipment is used in various operators. 3G equipment puts forward new requirements for optical cables, and the use of optical cables to connect outdoor transmission equipment has become the main requirement at this stage. [0003] The lateral pressure resistance, tensile ...
