The optical fiber coupling device includes a first patch strip having a first plurality of optical fiber connectors arranged along a face of the first patch strip and a second patch strip having a second plurality of optical fiber connectors arranged along a face of the second patch strip. The first and second patch strips are in a stacked arrangement where the second plurality of optical fiber connectors is offset from the first plurality of optical fiber connectors in a first and a second direction transverse to a stacking direction. The offsetting improves access to the individual optical fiber connectors which assists an operative when managing or maintaining optical fiber connections and helps to reduce the likelihood of fatigue or failure since adjacent optical fiber connections are undisturbed during this process and the optical fiber connections may be easily accessed without needing to move or manipulate adjacent patch strips. ## Claims ### Claim 1 An optical fibre coupling device, comprising: a first patch strip comprising a first plurality of optical fibre connectors arranged along a face of said first patch strip; and a second patch strip comprising a second plurality of optical fibre connectors arranged along a face of said second patch strip, said first and second patch strips being in a stacked arrangement where said second plurality of optical fibre connectors is offset from said first plurality of optical fibre connectors in a first and a second direction transverse to a stacking direction. ### Claim 2 (depends on 1) The optical fibre coupling device as claimed in claim 1, wherein said first patch strip comprises an elongate strip and said first plurality optical fibre connectors is arranged in a longitudinal direction along said face of said first patch strip and said second patch strip comprises an elongate strip and said second plurality of optical fibre connectors is arranged in a longitudinal direction along said face of said second patch strip, said second patch strip being in said stacked arrangement adjacent said first patch strip to offset said second plurality optical fibre connectors in said first direction which is transverse to said longitudinal direction, rearward of said first plurality of optical fibre connectors and to offset said second plurality of optical fibre connectors in said second direction which is said longitudinal direction. ### Claim 3 (depends on 1) The optical fibre coupling device as claimed in claim 1, wherein said second patch strip is in said stacked arrangement adjacent said first patch strip to offset said second plurality of optical fibre connectors in said second direction and align said second plurality of optical fibre connectors with regions between optical fibre connectors of said first plurality of optical fibre connectors. ### Claim 4 (depends on 1) The optical fibre coupling device as claimed in claim 1, wherein said face of said first and second patch strips are sloped. ### Claim 5 (depends on 1) The optical fibre coupling device as claimed in claim 1, wherein said first and second plurality of optical fibre connectors are each operable to receive an optical fibre routed to an associated dwelling unit. ### Claim 6 (depends on 5) The optical fibre coupling device as claimed in claim 5, wherein said first and second patch strips form part of respective first and second trays each operable to receive optical fibres routed to associated dwelling units. ### Claim 7 (depends on 6) The optical fibre coupling device as claimed in claim 6, wherein said first and second trays are pivotally connected with a support structure to enable said first and second trays to be pivoted from said stacked position. ### Claim 8 (depends on 6) The optical fibre coupling device as claimed in claim 6, comprising: a securing arrangement operable to secure said first and second trays in said stacked position. ### Claim 9 (depends on 6) The optical fibre coupling device as claimed in claim 6, wherein said first and second trays are provided with complimentary engaging structures operable to retain said first and second trays in said stacked position. ### Claim 10 (depends on 1) The optical fibre coupling device as claimed in claim 1, wherein said first and second plurality of optical fibre connectors are each operable to receive a complimentary optical fibre connector coupled with an optical fibre routed from a provider. ### Claim 11 (depends on 10) The optical fibre coupling device as claimed in claim 10, wherein said first and second plurality of optical fibre connectors are each operable to receive an optical fibre routed to an associated dwelling unit, said first and second patch strips form part of respective first and second trays each operable to receive optical fibres routed to associated dwelling units, wherein said first and second trays are pivotally connected with a support structure to enable said first and second trays to be pivoted from said stacked position, and wherein each optical fibre connector is operable to mechanically retain an optical fibre. ### Claim 12 (depends on 11) The optical fibre coupling device as claimed in claim 11, comprising a passive optical device operable to couple the optical fibre to a dwelling unit with the optical fibre routed from a provider, the coupled optical fibre being routed through the optical fibre connector to provide only mechanical retention. ### Claim 13 (depends on 1) The optical fibre coupling device as claimed in claim 1, comprising: a parking strip having a third plurality of optical fibre connectors arranged along a face of said parking elongate strip, said parking strip being removably attachable to said second patch strip. ### Claim 14 (depends on 1) The optical fibre coupling device as claimed in claim 1, said optical fibre coupling device being provided within a multiple dwelling unit building distributor. ### Claim 15 A method of arranging an optical fibre coupling device, comprising the steps of: stacking a first patch strip comprising a first plurality of optical fibre connectors arranged along a face of said first patch strip and a second patch strip comprising a second plurality of optical fibre connectors arranged along a face of said second patch strip in an arrangement where said second plurality of optical fibre connectors is offset from said first plurality of optical fibre connectors in a first and a second direction.
