Abstract
An optical unit (5a, 5b) comprising a plurality of optical fibers (2) grouped together in a tube (3a, 3b) and optionally assembled into one or more ribbons inside tube. The tube (3a, 3b) has a Young's modulus less than 200 MPa and a Shore A hardness less than 90 at a temperature of approximately +20.degree. C. and a Young's modulus less than 2000 MPa at a temperature of approximately -40.degree. C. A fiber optic cable (10, 20) comprising at least one such optical unit (5a, 5b). Application of the cable to telecommunications.
