Claims

[Scope of utility model registration request]

Numerous protrusions are formed on the substrate to insert and protect the connected optical fiber cords, and the density of these protrusions is made partially different so that the straight and dovetail parts of the connected optical fiber cords can be inserted and protected. 1. A substrate for an optical fiber junction box, characterized in that the curved portions are configured to be inserted into areas where the density of protrusions is dense and areas where the protrusions are sparse.
