Abstract

The drop terminal includes a plurality of fiber optic adapters having outer connector ports that are accessible from outside the drop terminal. The drop terminal receives a fiber optic cable having a plurality of optical fibers. Fiber optic connectors are positioned at the ends of the optical fibers. The fiber optic connectors are inserted into inner connector ports of the fiber optic adapters. The drop terminal also includes an anchor block for securing the fiber optic cable to a main housing of the drop terminal. The anchor block can be secured to the main housing of the drop terminal by a mechanical interlock. The drop terminal may also include a transparent interior shield or liner that retains fibers in position within the drop terminal during assembly of the drop terminal.

Claims (29)

1. A drop terminal comprising:

a main housing enclosing an interior of the main housing, the main housing defining a cable port;

a plurality of fiber optic adapters mounted to the main housing, the fiber optic adapters including inner ports that are accessible from within the interior of the main housing and outer ports that are accessible from outside the main housing;

a fiber optic cable that enters/exits the interior of the main housing through the cable port, the fiber optic cable including a plurality of optical fibers and at least one strength member;

a plurality of fiber optic connectors mounted to ends of the optical fibers, the fiber optic connectors being located within the interior of the main housing and being inserted within the inner ports of the fiber optic adapters; and

an anchor block to which the at least one strength member of the fiber optic cable is secured, the anchor block being positioned within the interior of the main housing, the anchor block mechanically interlocking with the main housing to secure the fiber optic cable to the main housing, wherein the anchor block includes a main body having a first region to which the strength member of the fiber optic cable is secured, and a second region for fanning out the optical fibers of the fiber optic cable.

2. The drop terminal of claim 1 , wherein the second region includes a channel that extends away from the first region, the channel being configured to increase in width as the channel extends away from the first region.

3. The drop terminal of claim 2 , further comprising a divider positioned within the channel adjacent a wide end of the channel, the divider including a plurality of openings for separating the optical fibers.

4. The drop terminal of claim 1 , wherein the anchor block includes interlock tabs that fit within a receptacle defined by the main housing.

5. A drop terminal comprising:

a main housing enclosing an interior of the main housing, the main housing defining a cable port;

a plurality of fiber optic adapters mounted to the main housing, the fiber optic adapters including inner ports that are accessible from within the interior of the main housing and outer ports that are accessible from outside the main housing;

a fiber optic cable that enters/exits the interior of the main housing through the cable port, the fiber optic cable including a plurality of optical fibers and at least one strength member;

a plurality of fiber optic connectors mounted to ends of the optical fibers, the fiber optic connectors being located within the interior of the main housing and being inserted within the inner ports of the fiber optic adapters; and

an anchor block to which the at least one strength member of the fiber optic cable is secured, the anchor block being positioned within the interior of the main housing, the anchor block mechanically interlocking with the main housing within the interior to secure the fiber optic cable to the main housing, wherein the anchor block includes a main body having a central axis that extends from a first end to a second end of the main body, the anchor block including interlock tabs that project outwardly from the main body in opposite directions from the central axis of the main body, the interlock tabs being located adjacent the second end of the main body and being configured to interlock with the main housing,

wherein the fiber optic cable is secured to the anchor block adjacent the second end of the main body, and wherein the anchor block defines a fan-out channel that extends along the central axis of the main body for receiving and fanning out the optical fibers of the fiber optic cable.

6. The drop terminal of claim 5 , wherein the central axis of the main body aligns with a central axis of the fiber optic cable.

7. The drop terminal of claim 6 , wherein the fiber optic cable includes a buffer tube containing the optical fibers and also includes strength members positioned on opposite sides of the buffer tube, wherein the anchor block defines a central channel located adjacent the second end of the main body for receiving the buffer tube of the fiber optic cable, the central channel extending along the central axis of the main body, wherein the anchor block defines side channels positioned on opposite sides of the central channel for receiving the strength members of the fiber optic cable, and wherein the buffer tube is bonded within the central channel and the strength members are bonded with the side channels.

8. The drop terminal of claim 7 , wherein the fan-out channel extends from the central channel to the first end of the main body, wherein the fan-out channel widens as the fan-out channel extends toward the first end of the main body, and wherein a fiber divider is mounted within the fan-out channel adjacent the second end of the main body.

9. The drop terminal of claim 5 , wherein the cable port has an outer portion that is curved to provide bend radius protection to the fiber optic cable.

10. The drop terminal of claim 5 , wherein the main housing includes clamping portions that clamp the fiber optic cable within the cable port.

11. A drop terminal comprising:

a main housing including a first piece and a second piece that cooperate to enclose an interior of the main housing, the main housing defining a cable port between the first and second pieces, the main housing including clamping portions disposed adjacent to the cable port, the main housing also defining an anchor block receptacle within the interior of the main housing adjacent to the cable port;

a plurality of fiber optic adapters mounted to the main housing, the fiber optic adapters including inner ports that are accessible from within the interior of the main housing and outer ports that are accessible from outside the main housing;

a fiber optic cable that enters/exits the interior of the main housing through the cable port, the fiber optic cable including a central buffer tube containing a plurality of optic fibers, the fiber optic cable also including strength members positioned on opposite sides of the central buffer tube;

a plurality of fiber optic connectors mounted to ends of the optic fibers, the fiber optic connectors being located within the interior of the main housing and being inserted within the inner ports of the fiber optic adapters; and

an anchor block to which the strength members of the fiber optic cable are secured, the anchor block being positioned within the interior of the main housing, the anchor block including an interlock portion that fits within the anchor block receptacle of the main housing to mechanically interlock the anchor block with the main housing, wherein the anchor block includes a main body having a first region to which the strength members of the fiber optic cable are secured, and a second region for fanning out the optic fibers of the fiber optic cable.

12. The drop terminal of claim 11 , wherein the second region includes a channel that extends away from the first region, the channel being configured to increase in width as the channel extends away from the first region.

13. The drop terminal of claim 12 , further comprising a divider positioned within the channel adjacent a wide end of the channel, the divider including a plurality of openings for separating the optical fibers.
