1. A telecommunications cable comprising:
- a distribution cable including a cable jacket and at least a first buffer tube positioned within the cable jacket, the first buffer tube enclosing a first optical fiber, the distribution cable including a mid-span location where a portion of the cable jacket has been removed and where at least the first buffer tube includes a fiber access location through which the first optical fiber is routed out of the first buffer tube;
a tether that branches from the distribution cable at the mid-span location, the tether including a tether jacket, at least one strength member positioned within the jacket, a tether buffer tube positioned within the jacket, and a second optical fiber that extends through the tether buffer tube, the second optical fiber being spliced to the first optical fiber at a splice location; and
a tether retention block affixed to the distribution cable, the tether retention block including a first portion and a second portion that is configured to cooperate with the first portion to secure the tether buffer tube and at least the strength member of the tether, each of the first and second portions defining at least a first half-channel configured to cooperate with the first half-channel of the other portion to receive the strength member of the tether;
wherein the retention block defines a groove along which the distribution cable extends when the retention block is affixed to the distribution cable.

Abstract
A telecommunications cable includes a distribution cable, a tether that branches from the distribution cable, and a tether retention block affixed to the distribution cable. The tether retention block includes a first portion and a second portion that is configured to cooperate with the first portion to secure a tether buffer tube and a strength member of the tether. Each of the first and second portions defines at least a first half-channel configured to cooperate with the first half-channel of the other portion to receive the strength member of the tether.

10. A tether retention block for securing a tether cable to a distribution cable, the tether retention block comprising:
-
a first portion having a first side and an opposite, second side, the first side of the first portion defining at least a first groove; a second portion having a first side and an opposite, second side, the first side of the second portion defining at least a first groove configured to cooperate with the first groove of the first portion to define a passageway configured to receive a strength member and a tether buffer tube of the tether cable; wherein the first portion defines a third groove configured to receive the distribution cable to secure the tether cable to the distribution cable, the third groove being separate from the passageway. - View Dependent Claims (11, 12, 13)

14. A telecommunications cable comprising:
-
a distribution cable including a cable jacket and at least a first buffer tube positioned within the cable jacket, the first buffer tube enclosing a first optical fiber, the distribution cable including a mid-span location where a portion of the cable jacket has been removed and where at least the first buffer tube includes a fiber access location through which the first optical fiber is routed out of the first buffer tube; a tether that branches from the distribution cable at the mid-span location, the tether including a tether jacket, at least one strength member positioned within the jacket, a tether buffer tube positioned within the jacket, and a second optical fiber that extends through the tether buffer tube, the second optical fiber being spliced to the first optical fiber at a splice location; a tether retention block affixed to the distribution cable, the tether retention block including a first portion and a second portion that is configured to cooperate with the first portion to secure the tether buffer tube and at least the strength member of the tether, each of the first and second portions defining at least a first half-channel configured to cooperate with the first half-channel of the other portion to receive the strength member of the tether; a separation block coupled to the distribution cable at an opposite side of the mid-span location from the tether retention block, the separation block at least partially enclosing the first optical fiber; and a tube extending from the separation block to the tether retention block, wherein the second optical fiber splices to the first optical fiber within the tube. - View Dependent Claims (15)
