Technical requirements for 1-core covered optical cable
Most covered optical cables are single-core or double-core structures, and can also be made into a four-core structure. The cross-section is in the shape of an 8-shaped one. The reinforcement is located at the center of the two circles. It adopts metal or non-metal structure, and the optical fiber is located in the geometric center of the figure-8 shape.
The optical fiber in the covered optical cable adopts G.657 small bending radius optical fiber, which can be laid with a bending radius of 20mm, and is suitable for entering the building through pipes or open wires.
Technical requirements for laying covered optical cables without rigid contact; ensuring steering installation The radius of curvature is greater than 30mm; it has sufficient mechanical strength and reliable performance; it has the ability to withstand dynamic stress (such as vibration or dancing); it can ensure construction quality without relying on the proficiency of the operation as much as possible, and the operation is convenient and fast; The aerial hanging wire is beautiful and compact, and does not affect other lines used.
