Method for laying optical fiber cable

1. A method for laying an optical fiber cable including a cable core that includes a plurality of optical fibers, a cable sheath that includes an inner jacket disposed at a radially outer side of the cable core, and an outer jacket disposed at a radially outer side of the inner jacket, and at least one tensile strength member embedded in the outer jacket, a first kinetic friction coefficient of the outer jacket with respect to a duct being smaller than a second kinetic friction coefficient of the inner jacket with respect to the duct, first flame retardance of the inner jacket being higher than the second flame retardance of the outer jacket, the method comprising:

wiring the optical fiber cable in an outdoor side via the duct;

drawing the optical fiber cable from the outdoor side to an indoor side;

making a part of the optical fiber cable as an optical fiber cable for indoor wiring by removing the outer jacket after the drawing of the optical fiber; and

wiring the optical fiber cable for indoor wiring in the indoor side.

2. The method for laying an optical fiber cable according to claim 1 ,

wherein in the wiring the optical fiber cable in the outdoor side, the optical fiber cable is passed through the duct by air pressure-feeding.

3. The method for laying an optical fiber cable according to claim 1 ,

wherein a first connector is connected to end portions of the plurality of optical fibers,

the method for laying an optical fiber cable further comprises:

storing the optical fiber cable for indoor wiring in a connection box installed in the indoor side; and

connecting the first connector with a second connector connected to another optical fiber in the connection box.
