After long-distance transmissions, be intended to realization and register one's residence, butterfly optical cable is used as the main carriers of fiber entering household more at present.Butterfly optical cable
Also known as covered wire cable, which is gained the name because cross-sectional shape is similar to butterfly, and it is to disperse for stress in rubber-insulated wire that the both sides of butterfly optical cable are
The reinforcement carried with stress, middle are optical fiber, and being large-scale application in fiber to the home (FTTH) network, user introduces
The optical cable of section, is also applied for the use of the networks such as Fiber-To-The-Office (FTTO) and the FTTB (FTTB) of other intelligent acess
Family introduces the optical cable of section.Two end connectors of traditional butterfly optical cable include the fixed component with salient point and the lock pin with concave point
Positioning element, butterfly optical cable were first snapped in the fixed component of joint in lock pin positioning element before being docked with joint unit, order
Salient point snaps in concave point to realize positioning assembling, and in installation process, optical fiber is penetrated fixed component by experience by staff, then will
Joint unit is inserted in the joint for combining.The outside of existing butterfly cable is not provided with sheath, easily damages, and had only sets
Put one layer of rubber outer protection set effectively to be protected, can not find in time when sheath is damaged.
Utility model content
The purpose of this utility model is to provide the butterfly optical cable based on circular jacket, to solve to carry in above-mentioned background technology
The problem for going out.
For achieving the above object, the utility model provides following technical scheme：Based on the butterfly optical cable of circular jacket, including
