Claims

[Scope of utility model registration request]

In an optical module constituting an optical fiber transmission system, a functional part having a receiving or transmitting function is fixed inside the box of the optical module, and a part of the fiber cable drawn out from the functional part near the functional part is a fiber cable. A helical part is formed by winding the fiber cable into a spiral shape, and a passage for the fiber cable is provided in the box of the optical module to allow the helical part to freely expand and contract. 1. An optical module characterized in that a normal part where the shaped part ends and becomes a straight line has a cable pull-out hole through which the normal part can freely go in and out.
