Abstract

A system and method for blowing an optical fiber to a destination are provided. A fiber blowing device may include an air inlet for receiving and conveying pressurized air from an air source through a bore of the blowing device. An optical fiber may be inserted into the device through a fiber inlet. A conduit may further be connected to the fiber blowing device, the conduit connecting the source location with the destination location. The optical fiber may be blown through the blowing device and the conduit using a drag force. The fiber blowing device may further include an acoustic measurement device for measuring distance and a display screen for displaying a variety of information.

Claims

1. An optical fiber blowing device, the apparatus comprising:

an elongated bore for receiving and conveying an optical fiber; and

an acoustic measurement device configured for approximating the length of a conduit coupled to the bore.

2. The device of claim 1, wherein the acoustic measurement device includes an acoustic transmitter and an acoustic sensor and is configured to approximate a distance between the source location and the destination.

3. The device of claim 2, further comprising a display screen, wherein the display screen displays distance data determined by the acoustic measurement device.

4. The device of claim 2, wherein the display screen displays a reel type corresponding to the approximated distance.

5. The device of claim 2, further comprising a controller to control the acoustic transmitter to emit a short sound burst.

6. The device of claim 5, wherein the acoustic measurement device approximates the distance between the source location and the destination by determining a delay between the emission of the short sound burst and reception of a reflection of the short sound burst.

7. The device of claim 1, wherein the acoustic measurement device is positioned inside the elongated bore.

8. The device of claim 1, further comprising an air inlet coupled to the elongated bore.

9. A fiber blowing device comprising:

an elongated bore for receiving an optical fiber;

a fiber inlet connected to a second end of the elongated bore; and

an access panel extending longitudinally between the fiber inlet and the first end of the elongated bore enabling the removal of a portion of the optical fiber from the fiber blowing device.

10. The device of claim 9, wherein the access panel is pivotably mounted to the fiber blowing device.

11. The device of claim 9, wherein the access panel is attached to the fiber blowing device such that the fiber blowing device is airtight when the access panel is in a closed configuration.

12. The device of claim 9, further comprising an acoustic measurement device coupled to the bore, the acoustic measurement device comprising an acoustic transmitter and an acoustic sensor.

13. The device of claim 12, further comprising a display for displaying distance data determined by the acoustic measurement device.

14. The device of claim 13, further comprising a processor for controlling the acoustic measurement device and the display.

15. The device of claim 9, further comprising an air inlet angularly coupled to the bore.

16. A method for propelling an optical fiber through a conduit, the method comprising:

determining distance data between a source location and a destination location using a fiber blowing device; and

selecting a fiber dispensing reel from a plurality of dispensing reels having different lengths, wherein the selection is made based on the measured distance.

17. The method of claim 16, wherein the distance between the source location and the destination location is determined by an acoustic measurement device of the fiber blowing device.

18. The method of claim 17, wherein determining distance data between a source location and a destination location using the fiber blowing device further includes:

emitting a sound burst from an acoustic transmitter of the measurement device;

receiving, at an acoustic sensor of the acoustic measurement device, a reflection of the sound burst; and

determining a delay between the emission of the sound burst and the reception of the reflection of the sound burst.

19. The method of claim 16, further including displaying, on a display screen of the fiber blowing device, at least one of the identified dispensing reel and the measured distance data.

20. The method of claim 18, further including releasing the optical fiber from the fiber blowing device through an access panel.
