BI-SMF fiber G657B3 with high tensile strength 55 km spools Invisible Optical Fiber cable
 

BI-SMF fiber G657B3 Invisible optical cable is the abbreviation for transparent tight-buffered optical cable covered with hot melt glue. At the same time, the optical cable is almost transparent so it will not affect the indoor Beautiful, simple construction method, only need hand-held heating installation tools to complete the laying project.
It is an optical cable composed of G.657.B3 optical fiber, a transparent tight jacket layer, and a layer of hot melt adhesive.
Each layer is extruded step by step using an extrusion process, with a nominal outer diameter of 1.2mm.
 
The fiber used is BI-SMF fiber G657B3  with a minimum bending radius of 5mm. When laying, there is no need to nail, make brackets, perforate, make pipes, etc., to destroy the original indoor structure, or because of the discontinuity of the laying, the optical cable will sag and fall off and other safety hazards.
 
The application of invisible optical cable is the application where the user does not accept the use of leather fiber optic cable to enter the home or solves the problem of the user's difficulty in entering the home, especially in the old residential area and office.
