Optical fiber fanout devices and methods for forming the same

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, wherein the optical fiber tubing receiving opening comprises an insertable furcation tube holding block configured to receive a plurality of furcation tubes fixedly 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,
• wherein the housing further includes a deformable holding block receiving member configured to slidably receive the furcation tube holding block and to limit longitudinal movement of the furcation tube holding block relative to the fiber telescoping cavity.

A method of forming an optical fiber fanout device, comprising:

• providing a housing having a fiber telescoping cavity and a first and second deformable holding block receiving member therein, the second deformable holding block receiving member being positioned at a distance from the first deformable holding block receiving member to define an arc for an optical fiber extending therebetween through the fiber telescoping cavity;
• positioning a multi-fiber grouping of a plurality of optical fibers in a multi-fiber holding block configured to be received in the first and/or second deformable holding block receiving member;
• fixedly securing a plurality of furcation tubes in a furcation tube holding block configured to be received in the first and/or second deformable holding block receiving member;
• singulating ones of a plurality of optical fibers in the multi-fiber grouping;
• inserting the singulated ones of the plurality of optical fibers in corresponding ones of the furcation tubes;
• positioning the furcation tube holding block a selected longitudinal distance from the multi-fiber holding block with the singulated optical fibers extending therebetween;
• fixedly securing the furcation tube holding block at the selected longitudinal distance from the multi-fiber holding block;
• and then
• inserting the multi-fiber holding block in the first deformable holding block receiving member;
• and
• inserting the furcation tube holding block in the second deformable holding block receiving member with the singulated optical fibers extending through the fiber telescoping cavity along the arc.
