Abstract

An inlet device is described for inserting a telecommunication cable into a telecommunications enclosure. The inlet device includes a housing compressible portion and a strength member securing section configured to fasten at least one strength member of the cable to the housing. The cable is centered in the housing when a protective sleeve is applied over a compressible portion of the housing. A method for preparing a cable assembly is also described. A telecommunications enclosure including an inlet device is also described.

Claims (26)

1. An inlet device to be fitted to a communication cable, the device comprising:

a one piece tubular housing having a first end and a second end;

the housing having a compressible portion at the first end of the housing to conform to an outer surface of the communication cable;

the housing including a strength member securing section formed on the second end of the housing and configured to secure a strength member of an telecommunication cable to the housing; and

a protective sleeve fitted over the compressible portion to center the communication cable in the inlet device.

2. The inlet device of claim 1 , wherein the compressible portion includes a plurality of spaced apart flexible fingers.

3. The inlet device of claim 2 , wherein the flexible fingers include barbs on the terminal ends of the fingers that penetrate and grab a jacket of a telecommunications cable installed in the inlet device.

4. The inlet device of claim 1 , wherein the compressible portion includes a fluted entry portion.

5. The inlet device of claim 1 , wherein the housing comprises a polygonal shaped orientation control section formed on an outer surface of the housing that is engageable with a corresponding port in a telecommunications enclosure.

6. The inlet device of claim 1 , wherein the telecommunication cable is an optical fiber cable wherein the optical fiber cable comprises one or more optical fibers.

7. The inlet device of claim 6 , wherein the strength member securing section comprises at least one peripheral channel for retaining the at least one strength member and a central channel to accommodate the optical fibers.

8. The inlet device of claim 1 , further comprising a locking mechanism configured to secure the inlet device into a port of a telecommunications enclosure.

9. The inlet device of claim 1 , wherein the inlet device is installed into a port in a telecommunication enclosure.

10. A telecommunication enclosure comprising the inlet device of claim 1 installed into a port formed in the enclosure.

11. An optical fiber cable assembly, comprising:

an optical fiber cable having at least one optical fiber and at least one strength member;

an inlet device mounted on an end of the optical fiber cable, the inlet device comprising:

a one piece tubular housing having a first end and a second end; the housing having a compressible portion at the first end of the housing to conform to an outer surface of the communication cable;

the housing including a strength member securing section formed on the second end of the housing and configured to secure a strength member of an optical fiber cable to the housing; and

a protective sleeve fitted over the compressible portion to center the communication cable in the inlet device; and

an optical fiber connector attached to a terminal end of the optical fiber of the optical fiber cable.

12. The optical fiber cable assembly of claim 11 , including first and second inlet devices mounted on the cable.

13. An optical fiber cable assembly of claim 11 , wherein the optical fiber cable comprises one of a multi-fiber ribbon cable, single fiber cable and multi-fiber loose buffer tube cable.

14. The optical fiber cable assembly of claim 11 , wherein the cable assembly is installed into a port in a telecommunication enclosure.

15. The inlet device of claim 1 , wherein the inlet device comprises two strength member securing sections formed on the second end of the housing; each configured to secure a strength member of an optical fiber cable to the housing of the inlet device.

16. The optical fiber cable assembly of claim 11 , wherein the inlet device comprises two strength member securing sections formed on the second end of the housing; each configured to secure a strength member of an optical fiber cable to the housing of the inlet device.
