## Abstract

An optical connection box for housing an optical connection between a distribution cable and at least one drop cable of an optical access network includes a base. The base includes a bottom configured to house an excess length of a first optical fiber of a distribution cable in a first section of the interior and configured to house an excess length of a second optical fiber of a drop cable in a second section of the interior, a first sidewall having a slot and recessed configured to receive a duct housing the distribution cable, and a plurality of splice-holder elements extending from the bottom of the base and configured to house at least one splice between the first optical fiber of the distribution cable and either (i) the second optical fiber of the drop cable, or (ii) an optical fiber pigtail that is coupled with the second optical fiber of the drop cable. The first section and the second section are disposed on opposite sides of the splice-holder elements.

## Claims

### Claim 1

An optical connection box for housing an optical connection between a distribution cable and at least one drop cable of an optical access network, the optical connection box comprising:
a base including:
a bottom configured to house an excess length of a first optical fiber of a distribution cable in a first section of the interior and configured to house an excess length of a second optical fiber of a drop cable in a second section of the interior;
a first sidewall having a slot and recessed configured to receive a duct housing the distribution cable;
a plurality of splice-holder elements extending from the bottom of the base in a center region of the interior; and
a pair of bulkhead holders extending from the bottom of the base,
wherein the first section and the second section are disposed on opposite sides of the center region,
wherein the first section includes a first storage region configured to receive an SC pigtail that includes a slack portion wrapped in the arcuate or circular path of the first storage region,
wherein a shrinkwrap covers a splice of an end of the SC pigtail with a fiber of the distribution cable entering the interior via the slot,
wherein the shrinkwrap is held in a desired orientation by a subset of the plurality of the splice-holder elements,
wherein the subset of the plurality of the splice-holder elements are sized, spaced apart from one another and configured such that the shrinkwrap is held in an interference fit or friction fit relationship by the subset of the plurality of the splice-holder elements,
wherein a second end of the pigtail includes an SC connector configured to be coupled with a first port of an SC bulkhead configured to be held by the bulkhead connector,
wherein the drop cable is configured with a first end terminated with an SC connector that is configured to be coupled with a second port of the SC bulkhead such that the SC connectors are configured to be optically coupled to one another, and
wherein bottom includes an opening configured to receive the drop cable to be fed to an end user.
