Optical fiber fanout devices and methods for forming the same
First Claim
1. An optical fiber fanout device, comprising:
- a housing having a fiber telescoping cavity therein;
an optical fiber tubing receiving opening in the housing that extends to the fiber telescoping cavity, the optical fiber tubing receiving opening being configured to secure a plurality of optical fiber tubes therein; and
an optical fiber receiving opening in the housing that extends to the cavity, the optical fiber receiving opening being displaced from the optical fiber tubing receiving opening by a distance selected to define an arc for an optical fiber extending from the optical fiber receiving opening to the optical fiber tubing receiving opening that exceeds a minimum bend radius for the optical fiber, andwherein the fiber telescoping cavity is sized to accommodate the arc for the optical fiber and differential thermal expansion and contraction of the optical fiber without accommodating additional lengths of the optical fiber so that the optical fiber defines only a single semi-circular arc when installed in the optical fiber fanout device.

Abstract
Optical fiber fanout devices include a housing having a fiber telescoping cavity therein. An optical fiber tubing receiving opening in the housing extends to the fiber telescoping cavity. The optical fiber tubing receiving opening is configured to secure a plurality of optical fiber tubes therein. An optical fiber receiving opening in the housing also extends to the cavity. The optical fiber receiving opening is displaced from the optical fiber tubing receiving opening by a distance selected to define an arc for an optical fiber extending from the optical fiber receiving opening to the optical fiber tubing receiving opening that exceeds a minimum bend radius for the optical fiber.
