MICROTUBES ENCLOSED IN FABRIC FOR AIR-BLOWN FIBERS Russian patent published in 2022 - IPC G02B6/44 

FIELD: communication.

SUBSTANCE: invention relates to a system of tubes that are adapted to the reception to optical fiber systems and that are used in the field of communication, in particular to such tubes that are enclosed in fabric material. The claimed device to be inserted into a pipeline includes at least one tube intended to accommodate optical fibers or fiber-optical micro-cables. The tube is surrounded by a casing. In the embodiment, in which there is a set of tubes, they are freely installed in a line inside the casing. According to another embodiment, opposite surfaces of the casing are attached to each other to form compartments for each tube. According to one more embodiment, tubes are held in the casing mainly in a bundle. In addition, the tube casing can be attached to one or several inner cable channels, each of which can receive a fiber-optical cable. As an option, the inner cable channel can be attached to two casings, each of which contains a tube.

EFFECT: creation of a device that simplifies the input of communication micro-cables or optical fibers to tubes located in the pipeline, or simplifies the input of a communication cable to the pipeline already having a tube.
