The furcation module holder includes a cable anchoring location. Each of the furcation modules has a furcation tube mounting insert and a plurality of furcation tubes. The furcation tubes are supported by the furcation tube mounting inserts and have free portions that extend outwardly from the furcation tube mounting inserts and from the furcation module holder. The furcation tubes can hold optical fibers of a cable that extends from the subassembly to a cable spool. The subassembly and the free portions of the furcation tubes can be packaged together until installation. ## Claims ### Claim 1 A fan-out subassembly adapted to be connected to a main component, the fan-out sub-assembly comprising: a furcation module holder configured to be mounted to the main component, the furcation module holder including a cable anchoring location; and a plurality of furcation modules each having a furcation tube mounting insert and a plurality of furcation tubes, the furcation tubes being supported by the furcation tube mounting inserts, the furcation tubes having free portions that extend outwardly from the furcation tube mounting inserts, the furcation tube mounting inserts being mounted to the furcation module holder and at least sections of the free portions of the furcation tubes extending outwardly from the furcation module holder. ### Claim 2 (depends on 1) The fan-out subassembly of claim 1, further comprising a cable anchored to the furcation module holder at the cable anchoring location, the cable having a plurality of optical fibers routed through the furcation tubes of the furcation modules. ### Claim 3 (depends on 2) The fan-out subassembly of claim 2, wherein the cable includes an outer jacket surrounding a plurality of buffer tubes, and wherein a plurality of the optical fibers are positioned within each of the buffer tubes. ### Claim 4 (depends on 3) The fan-out subassembly of claim 3, wherein the cable includes a tensile reinforcing structure that is anchored to the furcation module holder. ### Claim 5 (depends on 4) The fan-out subassembly of claim 4, wherein the tensile reinforcing structure includes aramid yarn. ### Claim 6 (depends on 5) The fan-out subassembly of claim 5, wherein the jacket of the outer cable is secured to the furcation module holder. ### Claim 7 (depends on 6) The fan-out subassembly of claim 6, wherein the jacket is secured to the furcation module holder by a cable tie. ### Claim 8 (depends on 1) The fan-out subassembly of claim 1, wherein the furcation tube mounting inserts are stacked on the furcation module holder. ### Claim 9 (depends on 1) The fan-out subassembly of claim 1, wherein the furcation module holder is mounted to the main component by a structure selected from the group consisting of a fastener, a latch, a hook, a tab, a snap-fit, and a flange. ### Claim 10 (depends on 1) The fan-out subassembly of claim 1, wherein the main component is selected from a group consisting of a telecommunications housing, a telecommunications panel, and a telecommunications shelf. ### Claim 11 (depends on 1) The fan-out subassembly of claim 1, wherein the furcation module holder is elongated along an axis, wherein the furcation module holder includes a base having a length that extends along the axis from a first end to a second end of the furcation module holder, wherein the furcation module holder includes an end wall provided at the first end of the furcation module holder, wherein a cable pass-through fitting for receiving the cable is mounted at the end wall, and wherein the furcation tube mounting inserts are stacked adjacent the second end of the furcation module holder. ### Claim 12 (depends on 11) The fan-out assembly of claim 11, wherein the furcation module holder includes opposing side walls that extend between the first and second ends of the furcation module holder and that cooperate with the base to define an open-topped channel that extends along the axis of the furcation module holder, wherein the furcation tube mounting inserts are mounted between the opposing side walls, wherein the cable anchoring location is positioned at an intermediate location between the first and second ends of the furcation module holder, and wherein the optical fibers are routed through the open-topped channel from the anchoring location to the furcation modules. ### Claim 13 A method for installing a fan-out subassembly at a first location, the fan-out subassembly including a furcation module holder and a plurality of furcation modules, the method comprising: pre-assembling the fan-out subassembly at a second location that is remote from the first location, the pre-assembling including securing a cable to the furcation module holder, routing optical fibers of the cable through furcation tubes of the furcation modules, and securing the furcation modules to the furcation module holder; transporting the pre-assembled fan-out assembly from the second location to the first location; and mounting the pre-assembled fan-out assembly to a main component provided at the first location. ### Claim 14 (depends on 13) The method of claim 13, wherein the first location is a field location and the second location is an assembly facility. ### Claim 15 (depends on 13) The method of claim 13, wherein the assembly facility is selected from the group consisting of a factory, a warehouse, and an office. ### Claim 16 (depends on 13) The method of claim 13, wherein the cable includes an outer jacket surrounding a plurality of buffer tubes, and wherein the plurality of the optical fibers are positioned within the buffer tubes, and wherein the cable includes a tensile reinforcing structure that is anchored to the furcation module holder. ### Claim 17 A kit comprising: a cable spool assembly including an optical cable wrapped around a spool, the optical cable including an outer jacket surrounding a plurality of buffer tubes, each of the buffer tubes holding a plurality of optical fibers; and a fan-out subassembly into which a portion of the optical cable is routed, the fan-out subassembly including: a furcation module holder configured to be mounted to the main component, the furcation module holder including a cable anchoring location at which the optical cable is secured to the furcation module holder; and a plurality of furcation modules each having a furcation tube mounting insert and a plurality of furcation tubes, the furcation tubes being supported by the furcation tube mounting inserts, the furcation tubes having free portions that extend outwardly from the furcation tube mounting inserts, the furcation tube mounting inserts being mounted to the furcation module holder and at least sections of the free portions of the furcation tubes extending outwardly from the furcation module holder, wherein the optical fibers of the optical cable are routed through the furcation tubes of the furcation modules. ### Claim 18 (depends on 17) The kit of claim 17, further comprising packaging holding the fan-out subassembly.
