How is coiled, twisted or roped fibers terminated?
Generally terms the same techniques as with PMMA apply, because this optics are no more that 0,75mm diameter PMMA fibers bunched mutually. In the case of coiled optics the sheath and the internal core (whether existing) has to be removed due to the different nature, physic characteristics and melting point regarding the fibers. Wherever possible both extremes of a sidelight light guide must be glass polished and fused.
