Fiber optic telecommunications cable assembly
First Claim
1. A fiber optic telecommunications cable assembly comprising:
- a main fiber optic cable;
a tether cable that branches from the main fiber optic cable at a breakout location;
a breakout block mounted to the main fiber optic cable at the breakout location, the breakout block defining a straight-through channel in which the main fiber optic cable is received and a breakout channel that branches out from the straight-through channel, the breakout block including first and second half-pieces joined at oppositely positioned first and second seams, the first seam being positioned adjacent the straight-through channel and the second seam being positioned adjacent the breakout channel;
an optical fiber structure that extends from the main fiber optic cable, through the breakout block to the tether cable; and
an over-mold that covers the breakout block and at least a portion of the main fiber optic cable;
wherein the first and second half-pieces of the breakout block include a first set of inner and outer overlap members that extend along the second seam and overlap one another to provide a first barrier that prevents over-mold material from entering the breakout block through the second seam.

Abstract
The present disclosure relates to a fiber optic telecommunications cable assembly including a main fiber optic cable and a tether cable that branches from the main fiber optic cable at a breakout location. The fiber optic telecommunications cable assembly also includes a breakout block mounted to the main fiber optic cable at the breakout location, and an over-mold that covers the breakout block and at least a portion of the main fiber optic cable. The breakout block defines a straight-through channel in which the main fiber optic cable is received and a breakout channel that branches out from the straight-through channel. The breakout block includes seams with overlap configurations that prevent the over-mold from entering the breakout block through the seams. The breakout block also includes barrier dams for preventing bonding material from entering the breakout channel.

13. A fiber optic telecommunications cable assembly comprising:
-
a main fiber optic cable; a tether cable that branches from the main fiber optic cable at a breakout location, the tether cable having a central buffer tube and two strength members positioned at opposite sides of the central buffer tube; at least one crimp member crimped on the tether cable; a retention block mounted to the main fiber optic cable at the breakout location, the retention block defining a straight-through channel in which the main fiber optic cable is received and a tether mounting channel for receiving one end of the tether cable, the tether mounting channel including a cable anchoring portion including a central region for receiving the central buffer tube and side regions for receiving the strength members, the cable anchoring portion also including a pocket that receives the at least one crimp member; an optical fiber structure that extends from the main fiber optic cable, through the retention block to the tether cable; and a bonding material that secures the strength members in the side regions of the cable anchoring portion of the retention block.
