Power, II - Web page: https://patentgrep.com/patent/US11994731B2 ## CPC - G02B 6/4446: {Cable boxes, e.g. splicing boxes with two or more multi fibre cables} - G02B: OPTICAL ELEMENTS, SYSTEMS OR APPARATUS ## Abstract An optical fiber pedestal box comprises a pedestal having a rail and an optical fiber box configured to mount to the pedestal. The optical fiber box is restricted in movement by at least one cable and the pedestal is configured to slide relative to the optical fiber box to accommodate cables moving because of ground heaving during freezing and thawing. The optical fiber pedestal box may be configured to receive different sizes and types of optical fiber cables. ## Claims ### Claim 1 An optical fiber pedestal box comprising: a pedestal having a single rail positioned at a rear panel of the pedestal; an optical fiber box having a plurality of protruding bolts configured to slidably engage with the single rail of the pedestal and to restrict movement of the optical fiber box to a vertical direction relative to the pedestal; and a cable entrance plate assembly configurable to receive different sizes of optical fiber cables; wherein the optical fiber box is restricted in movement by at least one cable. ### Claim 2 (depends on 1) The optical fiber pedestal box of claim 1, wherein the movement of the optical fiber box is restricted to a range determined by the at least one cable. ### Claim 3 (depends on 1) The optical fiber pedestal box of claim 1, wherein the cable entrance plate assembly comprises a cable entrance plate and a top piece configured to couple to the cable entrance plate. ### Claim 4 (depends on 3) The optical fiber pedestal box of claim 3, wherein the cable entrance plate comprises a plurality of channels of different widths for defining ports of varying sizes. ### Claim 5 (depends on 4) The optical fiber pedestal box of claim 4, wherein at least one channel of the plurality of channels comprises a plurality of marked portions configured to be breakable so as to adjust a length of the at least one channel. ### Claim 6 (depends on 5) The optical fiber pedestal box of claim 5, wherein the top piece comprises a plurality of prongs configured to interleave between the plurality of channels when the top piece is coupled to the cable entrance plate. ### Claim 7 (depends on 6) The optical fiber pedestal box of claim 6, wherein the cable entrance plate further comprises at least one edge configured to receive the plurality of prongs of the top piece. ### Claim 8 (depends on 7) The optical fiber pedestal box of claim 7, wherein the at least one edge is rolled over. ### Claim 9 (depends on 3) The optical fiber pedestal box of claim 3, wherein the top piece further comprises a side portion having a cable tie area. ### Claim 10 An optical fiber pedestal box comprising: a pedestal having a single rail positioned at a rear panel of the pedistal; an optical fiber box having a plurality of protruding bolts configured to slidably engage with the single rail of the pedestal and to restrict movement of the optical fiber box to a vertical direction relative to the pedestal; and a cable entrance plate assembly coupled to the optical fiber box and configurable to receive different sizes of optical fiber cables; wherein the cable entrance plate assembly comprises a plurality of channels of different widths for defining optical fiber cable ports of varying sizes, at least one channel of the plurality of channels having a plurality of marked portions configured to be breakable so as to adjust a length of the at least one channel for defining optical fiber cable ports of varying sizes. ### Claim 11 (depends on 10) The optical fiber pedestal box of claim 10, wherein the cable entrance plate assembly comprises a first plate including the plurality of channels, and a second plate configured to couple to the first plate. ### Claim 12 (depends on 11) The optical fiber pedestal box of claim 11, wherein the second plate comprises a plurality of prongs configured to interleave between the plurality of channels when the second plate is coupled to the first plate. ### Claim 13 (depends on 12) The optical fiber pedestal box of claim 12, wherein the first plate comprises at least one edge configured to receive the plurality of prongs. ### Claim 14 (depends on 13) The optical fiber pedestal box of claim 13, wherein the second plate further comprises a cable tie area. ### Claim 15 (depends on 10) The optical fiber pedestal box of claim 10, wherein the pedestal is configured to mount to a ground and slide relative to the optical fiber box so as to accommodate movement of optical fiber cables with the ground freezing and thawing. ### Claim 16 (depends on 15) The optical fiber pedestal box of claim 15, wherein the rail is configured to slide relative to the optical fiber box. ### Claim 17 (depends on 15) The optical fiber pedestal box of claim 15, wherein movement of the optical fiber box is restricted by the optical fiber cables. ### Claim 18 An optical fiber pedestal box comprising: a pedestal having a single rail positioned at a rear panel of the pedestal; an optical fiber box having a plurality of protruding bolts configured to slidably engage with the single rail of the pedestal and to restrict movement of the optical fiber box to a vertical direction relative to the pedestal; and a cable entrance plate assembly configurable to receive different sizes of optical fiber cables; wherein the cable entrance plate assembly comprises a first plate including the plurality of channels, and a second plate configured to directly couple to the first plate. ### Claim 19 (depends on 18) The optical fiber pedestal box of claim 18, wherein the second plate comprises a plurality of prongs configured to interleave between the plurality of channels when the second plate is coupled to the first plate.
