Abstract

Optical patch panels are disclosed. In one example, a housing module may include at least one wall arranged to present connectors for mating with optical cables. A plurality of trunk connectors may be arranged in at least one wall of the housing module, each of the trunk connectors being connectable to an optical trunk line entering the housing module. A plurality of duplex fiber connectors may be arranged in at least one wall of the housing module, the duplex fiber connectors being operable to mate with downstream networking equipment, the duplex fiber connectors being arranged in clusters, each cluster presenting a group of four pairs of duplex fiber connectors. The duplex fiber connectors in a cluster may be optically coupled to one of the plurality of trunk lines via the plurality of trunk connectors.

First claim

What is claimed is:

1. An optical patch panel, comprising:
a rack mount housing having a plurality of walls arranged to carry optical connectors to couple optical cables;
a plurality of trunk connectors carried by a first wall of the rack mount housing, the trunk connectors having at least 40 Gbps (gigabits per second) capacity and being connectable to an optical trunk line entering the rack mount housing;
a plurality of duplex fiber connectors arranged in a second wall of the rack mount housing, the duplex fiber connectors being operable to couple with downstream networking equipment, the duplex fiber connectors being arranged in clusters, each cluster presenting a group of four pairs of duplex fiber connectors having at least 10 Gbps capacity per pair;
a plurality of optical fibers within the rack mount housing connecting the duplex fiber connectors in a given cluster to a corresponding trunk connector; and wherein
each of the plurality of trunk connectors has a lateral position in the first wall relative to the rack mount housing, and wherein the cluster of the duplex fiber connectors to which any one of the trunk connectors is coupled is positioned at substantially the same lateral position in the second wall as the trunk connector to provide a mapping within the rack mount housing.

2. The panel of claim 1 , wherein each trunk connector and each duplex fiber connector is fixed to the rack mount housing to provide an interface to attach cables to the connectors.

3. The panel of claim 1 , further comprising a cassette installed within the rack mount housing, the cassette supporting the duplex fiber connectors.

4. The panel of claim 1 , further comprising a plurality of optical trunk lines, each being connectable to one of the trunk connectors, and each of the optical trunk lines including four pairs of optical fibers and being optically connectable to upstream networking equipment.

5. The panel of claim 1 , wherein the trunk connectors comprise MPO (Multiple Fiber Push-on Pull-off) connectors having twelve terminal pins.

6. The panel of claim 5 , wherein an upper left pair of duplex fiber connectors of each cluster are connected to first and twelfth terminal pins of the MPO connector, a lower left pair of duplex fiber connectors of each cluster are connected to second and eleventh terminal pins of the MPO connector, an upper right pair of duplex fiber connectors of each cluster are connected to third and tenth terminal pins of the MPO connector, and a lower right pair of duplex fiber connectors of each cluster is connected to fourth and ninth terminal pins of the MPO connector.

7. An optical patch panel, comprising:
a rack mount housing having a plurality of walls arranged to carry optical connectors to couple optical cables;
a plurality of trunk connectors carried by a first wall of the rack mount housing, the trunk connectors having at least 40 Gbps (gigabits per second) capacity and being connectable to an optical trunk line entering the rack mount housing;
a plurality of duplex fiber connectors arranged in a second wall of the rack mount housing, the duplex fiber connectors being operable to couple with downstream networking equipment, the duplex fiber connectors being arranged in clusters, each cluster presenting a group of four pairs of duplex fiber connectors having at least 10 Gbps capacity per pair; and
a plurality of optical fibers within the rack mount housing connecting a group of four pairs of the duplex fiber connectors in a given cluster to a corresponding trunk connector to map the plurality of duplex fiber connectors arranged in the second wall to the plurality of trunk connectors carried by the first wall.

8. The panel of claim 7 , wherein each trunk connector and each duplex fiber connector is fixed to the rack mount housing to provide an interface to attach cables to the connectors.

9. The panel of claim 7 , further comprising a cassette installed within the rack mount housing, the cassette supporting the duplex fiber connectors.

10. The panel of claim 7 , further comprising a plurality of optical trunk lines, each being connectable to one of the trunk connectors, and each of the optical trunk lines including four pairs of optical fibers which are optically connectable to upstream networking equipment.

11. The panel of claim 7 , wherein each of the plurality of trunk connectors has a lateral position on the rack mount housing, and wherein any one of the clusters of the duplex fiber connectors to which any one trunk connector is coupled is positioned at substantially the same lateral position as the trunk connector to provide a substantially straight-through mapping within the rack mount housing.

12. The panel of claim 7 , wherein at least 16 trunk connectors are provided, with at least 64 corresponding duplex fiber connectors.

13. The panel of claim 7 , wherein at least 32 trunk connectors are provided, with at least 128 corresponding duplex fiber connectors.

14. The panel of claim 7 , wherein the trunk connectors comprise MPO (Multiple Fiber Push-on Pull-off) connectors having twelve terminal pins.

15. The panel of claim 14 , wherein an upper left pair of duplex fiber connectors of each cluster are connected to first and twelfth terminal pins of the MPO connector, a lower left pair of duplex fiber connectors of each cluster are connected to second and eleventh terminal pins of the MPO connector, an upper right pair of duplex fiber connectors of each cluster are connected to third and tenth terminal pins of the MPO connector, and a lower right pair of duplex fiber connectors of each cluster is connected to fourth and ninth terminal pins of the MPO connector.

16. An optical patch panel, comprising:
a rack mount housing having a plurality of walls arranged to support connectors for mating with optical cables;
a plurality of trunk connectors carried by at least one of the walls of the rack mount housing, each of the trunk connectors having a predetermined signal capacity and being connectable to one of a plurality of optical trunk lines entering the rack mount housing; and
a plurality of duplex fiber connectors arranged in at least one of the walls of the rack mount housing, the duplex fiber connectors having a signal capacity of about one quarter of the predetermined signal capacity of the trunk connectors and being operable to mate with downstream networking equipment, the duplex fiber connectors being arranged in clusters, each cluster presenting a group of four pairs of duplex fiber connectors; wherein
the duplex fiber connectors in each cluster are optically coupled to one of the plurality of optical trunk lines via one of the plurality of trunk connectors, and wherein each of the plurality of trunk connectors has a lateral position on the rack mount housing, and wherein any one of the clusters of the group of four pairs of duplex fiber connectors to which any one trunk connector is coupled is positioned at substantially the same lateral position as is the respective trunk connector to provide a substantially straight-through mapping within the rack mount housing.

17. The panel of claim 16 , wherein each trunk connector and each duplex fiber connector are fixed to the rack mount housing to provide an interface for attaching cables to the connectors.

18. The panel of claim 16 , further comprising a cassette installed within the rack mount housing, the cassette having the duplex fiber connectors installed therein.

19. The panel of claim 16 , wherein at least 16 trunk connectors are provided, with at least 64 corresp
