Abstract
An optical fiber cable capable of absorbing water and resisting any undesirable increase of transmission loss caused by temperature variations. It has a core assembly formed by surrounding a stack of cores ( ) in e.g. ribbon form by a shock absorbing member ( ), at least one member ( ) of high tensile strength and a sheath ( ) formed from e.g. a thermoplastic resin and enclosing the core assembly and the high-tensile member ( ). The shock absorbing member ( ) is a strand of e.g. yarn not absorbing water, but carrying a water-absorbing resin.
