Abstract
The utility model relates to a security protection communication guard optical cable with loose optical fiber and tight optical fiber mixed together. The guard optical cable comprises a cable core and a sheath coated outside the cable core, and is characterized in that one or more loose tube fiber communication units and one or more tightly packaged fiber sensing units are arranged in the cable core. The utility model has the advantages that a loose structure required by optical fiber communication, as well as a tight structure required by optical fiber distributed sensing, can be kept, so that the communication and sensing functions of cable can simultaneously reach an optimum state. Besides security protection guard, the guard optical cable can also be popularized in other similar application ranges.
Description
Technical field
The utility model relates to communications optical cable and distributed sensing optical cable, relates in particular to a kind of security protection communication warning optical cable of degree of tightness fiber mix.
Background technology
Communication function for optical cable, the principle of design of its structure (comprising the light unit) is that the optical fiber in the cable is isolated as much as possible with influences such as external temperature, external force, vibration, wet damp environment, with assurance light signal reliable transmission under the condition that is not subjected to external action.Therefore, communications optical cable mainly adopts the loose structure technology, and promptly optical fiber relaxes in protection tube (light unit), makes relative protection tube of optical fiber and optical cable that enough redundant lengths (excess fiber length) be arranged.
For being used for the distributed sensing optical cable of security protection warning, its structure Design cardinal rule be allow outside some or certain is several sensitive and pass to optical fiber in the cable in real time by heat transfer agent.Therefore, sensing optic cable mainly adopts the locking structure technology, promptly adopts tightly packaged fiber light unit usually and almost do not have surplus length in light unit and optical cable.
Loose cable structure can be used for sensing, but common insufficient sensitivity; Tight jacketed cable can be used for communication, but extraneous disturbance influences communication quality easily.This shows: if require security protection warning optical cable to be used for communication and sensing simultaneously, no matter be the optical cable of locking structure or loose structure, the optical cable of single structure is not best to communication and sensing.
Summary of the invention
The purpose of this utility model provides a kind of security protection communication warning optical cable of degree of tightness fiber mix.
The technical solution adopted in the utility model is:
A kind of security protection communication warning optical cable of degree of tightness fiber mix comprises cable core and sheath, and described sheath is coated on the cable core outside, contains one or more loose tube fiber communication units and one or more tightly packaged fiber sensing unit in the described cable core simultaneously.
Also contain one or more reinforcement in the described cable core, and/or one or more gasket for packing.
Described cable core and sheath are combined into circular or non-circular optical cable, and described sheath has cheating colouration and/or camouflage surface.
The utility model has the advantages that: kept the desired loose structure of optical fiber communication to keep the desired locking structure of optical fiber distributed type sensing simultaneously, make the communication and the sensing function of optical cable reach optimum condition simultaneously, except being used for security protection warning aspect, also extend to other similar or similar ranges of application.
