First Claim
Patent Images
1. A method of blowing an optical fiber into a pipe comprising the steps of:
- providing an optical fiber path joint member defining a main path, the joint member having an inlet and an outlet at respective ends thereof and at least one joint path joining to said main path at an angle of equal to or less than 45°
,connecting a first portion of the pipe to said outlet,connecting a second portion of the pipe to said inlet, andintroducing said optical fiber into said joint path and blowing it therethrough and into the pipe via said main path.

4. A method of blowing an optical fiber comprising the steps of:
-
preparing an optical fiber path joint member which is divided into a first and second body parts, wherein a groove is formed on each of surfaces of said first and second body parts, and said groove forms a main path having an inlet and an outlet at respective ends thereof and at least one joint path joining to said main path in one direction at an angle of equal to or less than 45°
when said first and second body parts are assembled;cutting a pipe in which an optical fiber is previously laid; assembling said first and second parts to form said optical fiber path joint member at the position where said pipe is cut, while passing said previously laid optical fiber in said main path; connecting said main path to said pipe through said inlet and outlet, while connecting a joint pipe to said joint path; and blowing an optical fiber from the side of said joint pipe to said pipe through said joint path and main path. - View Dependent Claims (5, 6)

7. A method of blowing an optical fiber comprising the steps of:
-
preparing an optical fiber path joint member which is divided into a first and second body parts, wherein a groove is formed on each of surfaces of said first and second body parts, and said groove forms a main path having an inlet and an outlet at respective ends thereof and at least one joint path joining to said main path in one direction at an angle of equal to or less than 45°
when said first and second body parts are assembled;assembling said first and second parts to form said optical fiber path joint member at an end of a pipe where at least one optical fiber which is previously laid in said pipe is introduced out, while passing said previously laid optical fiber in at least one of said main path and said at least one joint path; sealing said main path and said at least one joint path; and blowing an optical fiber from one of said at least one joint path to said pipe through said main path. - View Dependent Claims (8)
