Abstract

A fiber access terminal includes a drop cable side and a distribution cable side. The sides are separated by a frame to which a variety of cable management and cable connection components may be mounted. Optical fibers are routed from drop and distribution cables through a plurality of routing paths to splice trays for connection to other optical fibers. A protective cover over the distribution side of the frame is included.

and

further comprising a splice holder mounted to the second side of the frame and cable management structures mounted to the second side of the frame defining a cable path for routing an optical fiber from the first side of the frame to the splice holder of the second side of the frame.

8. The fiber access terminal of claim 1, wherein a plurality of cable management structures are mounted to the first side of the frame and define a plurality of cable paths for optical fibers of the distribution cable, one of the cable paths for routing optical fibers from the distribution cable entering the enclosure to a second distribution cable exiting the enclosure and one of the cable paths for routing optical fibers from the distribution cable to the second side of the frame.

9. The fiber access terminal of claim 8, wherein a splice holder is mounted to the second side of the frame and the optical fibers from the distribution cable and the cable path of the first side of the frame are directed to the splice holder.

10. The fiber access terminal of claim 9, further comprising cable management structures mounted to the second side of the frame and defining a cable path for the optical fiber from the first side of the frame to the splice holder mounted to the second side of the frame.

11. The fiber access terminal of claim 10, wherein the cable management structures mounted to the second side of the frame also define a cable path from the splice holder to a cable entry for a customer drop cable entering the enclosure through the base on the second side of the frame.

12. The fiber access terminal of claim 4, further comprising at least one fiber optic adapter mounted to the second side of the frame and cable management structures mounted on the second side of the frame defining a cable routing path for the optical fiber from the first side of the frame to the fiber optic adapter.

13. The fiber access terminal of claim 1, further comprising a cover removably mounted about the first side of the frame within the enclosure to restrict access to the distribution cable and the plurality of optical fibers of the distribution cable on the first side of the frame.

14. The fiber access terminal of claim 3, wherein the splice holder mounted to the first side is configured to hold a plurality of splice trays substantially parallel to the first side of the frame.
