摘要： An optical transmission element that has an oil-containing filling compound and inside is provided with a two-layer outside sheath. The inside layer of the sheath is composed of a polyolefin and the outside layer is composed of a polyester, particularly of a polycarbonate. The shrinkage and swelling of the inside layer is largely compensated by the hard outside layer and the swelling portion, which usually appear at higher temperature, are kept extremely low.
