Abstract

Embodiments disclosed in the detailed description include a telescoping fiber optic module. The telescoping fiber optic module may be provided in a fiber optic equipment chassis which may be disposed in an equipment rack to support fiber optic connections. In embodiments disclosed herein, the telescoping fiber optic module is comprised of a fixed housing portion having an opening on a front side defining a passage inside the fixed housing portion. The fiber optic module is also comprised of a telescoping portion received in the passage inside the fixed housing portion. In this manner, the telescoping portion can telescope in and out of the fixed housing portion. This allows fiber optic connectors or adapters disposed in the telescoping portion and any connections made thereto to be telescoped out for improved access and telescoped back into the fixed housing portion when access is no longer needed.

Claims

1. A fiber optic module, comprising:

a fixed housing portion having an opening on a front side defining a passage inside the fixed housing portion, wherein the fixed housing portion includes a rear side opposite the front side configured to receive one or more rear side fiber optic adaptors or fiber optic connectors; and

a telescoping portion received in the passage and configured to telescope outward to the front of the fiber optic module.

2. The fiber optic module of claim 1, wherein the telescoping portion is configured to receive one or more fiber optic adaptors or connectors.

4. The fiber optic module of claim 1, further comprising at least one latching mechanism provided on the fixed housing portion configured to engage with the telescoping portion.

5. The fiber optic module of claim 4, wherein the at least one latching mechanism is disengaged to allow the telescoping portion to telescope out from the fixed housing portion.

6. The fiber optic module of claim 1, further comprising at least one latching mechanism provided on the fixed housing portion configured to engage with a fiber optic equipment chassis.

7. The fiber optic module of claim 1, wherein the telescoping portion further comprises:

a front section configured to receive one or more fiber optic adaptors or connectors; and

a rear section received in the passage that may telescope in and out of the passage.

8. The fiber optic module of claim 7, further comprising at least one latching mechanism disposed in the rear section configured to engage with the fixed housing portion.

9. The fiber optic module of claim 1, further comprising at least one rail disposed on the fixed housing portion.

10. The fiber optic module of claim 9, wherein the at least one rail is configured to be inserted into a rail guide disposed in a fiber optic equipment chassis to install the fiber optic module in the fiber optic equipment chassis.

11. The fiber optic module of claim 1, further comprising a removable cover.

12. The fiber optic module of claim 1, further comprising a cable routing guide or a slack management guide disposed in the passage inside the fixed housing portion.

13. The fiber optic module of claim 1, further comprising a cable harness disposed in the passage.

14. The fiber optic module of claim 1, further comprising a routing tray attached to the telescoping portion.

15. The fiber optic module of claim 14, wherein the routing tray is tiltable about the telescoping portion.

3. (canceled)

16. A fiber optic apparatus, comprising:

a chassis comprised of one or more slots; and

one or more telescoping fiber optic modules each comprising;

a fixed housing portion contained in a slot among the one or more slots, wherein the fixed housing portion includes a rear side opposite the front side configured to receive one or more rear side fiber optic adaptors or fiber optic connectors; and

a telescoping portion received in the fixed housing portion and configured to telescope in and out of the fixed housing portion.

17. The fiber optic apparatus of claim 16, wherein the one or more telescoping fiber optic modules each contain at least one rail received into at least one rail guide disposed in the chassis.

18. The fiber optic apparatus of claim 16, further comprising:

a first rail guide system disposed on a first side of the chassis;

a second rail guide system disposed on a second side of the chassis;

a first rail disposed on a first side of each of the one or more telescoping fiber optic modules and received into the first rail guide system; and

a second rail disposed on a second side of each of the one or more telescoping fiber optic modules and received into the second rail guide system.

19. The fiber optic apparatus of claim 18, further comprising at least one intermediate rail guide system disposed in the chassis between the first rail guide system and the second rail guide system.

20. The fiber optic apparatus of claim 19, further comprising at least one rail guide disposed on each side of the at least one intermediate rail guide system.

21. The fiber optic apparatus of claim 19, wherein at least one telescoping fiber optic module is received by a rail guide system formed by the first rail guide system and the at least one intermediate rail guide system;

and wherein another at least one telescoping fiber optic module is received by the rail guide system formed by the second rail guide system and the at least one intermediate rail guide system.

22. A fiber optic apparatus, comprising:

a chassis comprised of at least five horizontally-arranged rows each having one or more vertically-arranged slots;

at least five telescoping fiber optic modules each configured to support at least twelve fiber optic connections and disposed across a rows among the at least five horizontally-arranged rows among the one or more slots, each of the at least five telescoping fiber optic modules comprising;

a fixed housing portion contained in a slot among the one or more slots,

wherein the fixed housing portion includes a rear side opposite the front side configured to receive one or more rear side fiber optic adaptors or fiber optic connectors; and

a telescoping portion received in the fixed housing portion and configured to telescope in and out of the fixed housing portion.

23. The fiber optic apparatus of claim 22, wherein the telescoping portion is configured to receive one or more fiber optic adaptors or connectors.

24. The fiber optic apparatus of claim 22, further comprising at least one rail disposed on the fixed housing portion.

25. The fiber optic apparatus of claim 24, wherein the at least one rail is configured to be inserted into a rail guide disposed in the chassis to install the fiber optic module in the chassis.

26. The fiber optic apparatus of claim 22, further comprising a cable harness disposed in the passage.

27. The fiber optic apparatus of claim 22, further comprising a routing tray attached to the telescoping portion.

28. The fiber optic apparatus of claim 27, wherein the routing tray is tiltable about the telescoping portion.
