PFTTH (power fiber to the home) cable

Abstract

The invention belongs to the technical field of combination of wire cables and electric power and provides a PFTTH (power fiber to the home) cable. The PFTTH cable is characterized by comprising a first insulated conducting wire, a second insulated conducting wire, a butterfly optical cable, a first outer protection layer, a second outer protection layer, a third outer protection layer and a cavity, wherein the first outer protection layer covers the first insulated conducting wire; the second outer protection layer covers the second insulated conducting wire; the third outer protection layercovers the butterfly optical cable; the cavity is arranged in the third outer protection layer and can accommodate the butterfly optical cable; the first insulated conducting wire and the second insulated conducting wire are respectively arranged at the two sides of the butterfly optical cable; the first outer protection layer, the second outer protection layer and the third outer protection layer are in a one-body shape; and on any plane which is vertical to the axis of a first conductor, the outer edge of the third protection layer protrudes towards the cavity. According to the invention, the problems in the prior art that the cable is difficult to lay and tear out and the fiber density is low can be solved; and the PFTTH cable provided by the invention has the beneficial effects of stable heating performance, modularization, easiness for laying, producing, laying and constructing and the like.

Description

technical field [0001] The invention belongs to the technical field of cables and electric power, and in particular relates to a power optical fiber to the household cable. Background technique [0002] With the rapid development of information technology, people pay more and more attention to the transmission of high-bandwidth information, and the application of broadband is becoming more and more popular; as of the first quarter of 2010, the global broadband users reached 485 million, of which FTTX users rose to 65 million ; As of the first quarter of 2010, domestic broadband users reached 109 million, of which FTTX users rose to 15 million; because FTTX has a faster rate than DSL and easier upgrade solutions, the development of FTTX will be in the next few years will be very fast. [0003] With the advancement of my country's three-network integration and the rapid development of the power market, domestic power fiber-to-the-home access is gradually rising. As a necessi...

Problems solved by technology

The patent integrates optical fiber and power transmission and distribution cables, avoiding secondary wiring, reducing construction costs, and low network construction costs; providing huge bandwidth access; however, due to its thick outer diameter, inconvenient stripping, and inconvenient construction Factors such as convenience, so fail to popularize and use on a large scale; Another example, the patent title is: composite optical cable, announcement number CN2689263, which discloses a kind of composite optical cable with power transmission or transmission electric signal function concurrently, and it comprises cable core 10 1. A pair of conductor wires 20 with good electrical conductivity and capable of withstanding a certain voltage located on both sides of the cable core 10, and an outer sheath 30 outside the cable core 10 and the conductor wire 20. The cable core 10 includes an optical fiber 101 and a sheath The tight sleeve layer 102 placed outside the optical fiber 101 is characterized by: the tight sleeve layer 102 is wrapped around the optical fiber 101 without gaps; the diameter of the conductor wire 20 is greater than the diameter of the cable core 10; It has the advantages of filling cable paste, anti-lateral pressure, and good anti-bending effect; but its stripping performance is poor, and the number of optical fibers it accommodates is only a single, so it cannot meet the requirements of large-capacity communication
