Flame-retardant optical cable for air-blown installation

摘要

An optical cable (200) has a cable core comprising at least one tube (205) loosely accommodating optical fibers (210), the at least one tube being accommodated within a jacket (215) embedding at least two strength members (220), the cable core and the jacket comprising combustible material. A ratio core combustible material/jacket combustible material is lower than 60 vol%. The jacket is made of a composition having hardness of at least 60 Shore D and a LOI higher than 35%.
