Abstract

1,264,388. Optical fibres. CARL-ZEISSSTIFTUNG [trading as JENAER GLASWERK SCHOTT & GEN]. May 1, 1969 [May 2, 1968], No.22328/69. Heading G2J. [Also in Division C1] One or more black glass fibres 12 are fused into the outer surface of the sheath 10 of a conventional optical fibre 7 in order to absorb scattered light. A method of making the composite fibre is described (see Division Cl Abridgment).
