Zero Loss Bending Radius Bare Optical Fiber G657B3 FTTH transparent
invisible installation bare fiber optic cable
G657B3 Invisible optical cable is the abbreviation for transparent
tight-buffered optical cable covered with hot melt glue.
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 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.
The fiber used is G.657.B3 fiber 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.
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.
