Optical fiber drop cable
First Claim
1. An optical fiber drop cable comprising:
- an optical element section including an optical fiber wire, at least one pair of first tensile strength bodies disposed in parallel to the optical fiber wire in between, and a first cable sheath that covers said optical fiber wire and said first tensile strength bodies;
a cable support section including a second tensile strength body and a second cable sheath that covers said second tensile strength body; and
a neck portion that connects said optical element section and said cable support section in parallel to each other, wherein said neck portion includes a thick part disposed on the side of said cable support section, and a thin part, which is thinner than said thick part, disposed on the side of said optical element section.

Abstract
An optical fiber drop cable is provided with a neck portion in which an optical element section and a cable support section may be separated readily. The optical fiber drop cable 1 comprises the optical element section 9 including an optical fiber core wire 3, at least one pair of first tensile strength bodies 5 disposed in parallel to said optical fiber core wire in between, said optical fiber core wire and said first tensile strength bodies being covered with a cable sheath 7, and the cable support section 15 including a second tensile strength body 11 covered with a sheath 13, and the optical element section 9 and the cable support section 15 being fixed in parallel to each other via a neck portion 17. The neck portion 17 includes a thick part 25 formed on the cable support section 15 side and a thin part 23, which is thinner than the thick part 25, formed on the optical element section 9 side next to the thick part 25.

5. An optical fiber drop cable comprising,
a cable sheath which is made of thermoplastic resin, and which includes an optical fiber housing section covering an optical fiber wire and a pair of tensile strength bodies disposed on opposite sides of said optical fiber wire in the x direction, and having a pair of V shaped notches formed on opposite surfaces in the y direction, a support wire housing section covering a support wire, and disposed in parallel to said optical fiber housing section in the x-z plane; - and
a neck portion that connects said optical fiber housing section and said support wire housing section, wherein said neck portion includes a thin part formed on the optical fiber housing section side and having a generally even dimension in the y direction, and a thick part formed on the support wire housing section side and having a generally even dimension in the y direction which is larger than the thin part. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14)
