Fiber optic cable sub-assemblies and methods of making

A fiber optic cable assembly comprising:

• a fiber optic cable including at least one optical fiber, a cable jacket that houses the optical fiber, a first strength member, and a second strength member;
• a first fiber optic sub-assembly including a first collar with a first inner portion formed from a conductive material and a first outer portion formed from a dielectric material, the first inner portion seated within a cavity of the first outer portion, wherein:
• the first inner portion defines a first axial slot with opposite radial end portions and a central portion located between the opposite radial end portions,
• the first collar further includes a radial opening providing radial access to the axial slot of the inner portion,
• each strength member is disposed within a respective one of the opposite radial end portions of the first axial slot,
• the first inner portion comprises an outer axial end that is recessed within a cavity of the first outer portion of the collar,
• a first end portion of the optical fiber extends through:
• the central portion of the first axial slot of the first collar to protrude from an outer axial end of the first collar,
• a first connector housing that is attached to the first collar and electrically insulated from the inner portion of the first collar, and
• a first interface attached to the first end portion of the optical fiber, and
• the first interface is a total internal reflection block.

A method of assembling a fiber optic cable sub-assembly comprising:

• providing a fiber optic cable with at least one optical fiber, a cable jacket that houses the optical fiber, a first strength member, and a second strength member;
• providing a collar including an inner portion formed from a conductive material and an outer portion formed from a dielectric material, the inner portion seated within the outer portion, wherein the inner portion comprises an outer axial end that is recessed within a cavity of the outer portion and the inner portion defines an axial slot with opposite radial end portions and a central portion located between the opposite radial end portions, the collar further including a radial opening providing radial access to the axial slot;
• positioning each of the first strength member and the second strength member within a respective one of the opposite radial end portions, wherein a first end portion of the optical fiber extends through the collar to protrude from an outer axial end of the collar;
• crimping the opposite radial end portions of the inner portion to attach the first strength member and the second strength member to the respective one of the opposite radial end portions, wherein the radial opening facilitates the crimping;
• attaching a connector housing to the collar, wherein the outer portion of the collar electrically insulates the inner portion of the collar from the connector housing;
• and
• providing a cable boot for attaching the connector housing to the collar.

• the collar further includes a radial opening providing radial access into the axial slot,
• each strength member is disposed within a respective one of the opposite radial end portions of the axial slot, and
• the at least one optical fiber extends through the central portion of the axial slot of the collar such that the at least one optical fiber is disposed between the first strength member and the second strength member;
• a connector housing attached to the collar, wherein the outer portion of the collar electrically insulates the inner portion of the collar from the connector housing;
• and
• a cable boot for attaching the connector housing to the collar,
• wherein the radial opening provides a window for the at least one optical fiber to bend into the connector housing.
