Abstract

A fiber distribution terminal ( 30, 130, 230 ) including a housing ( 131, 231 ); and a spool arrangement ( 136, 236 ) that can rotate relative to the housing about an axis of rotation. The spool arrangement includes a drum portion ( 142, 242 ) centered on the axis of rotation and a flange ( 144, 146, 244, 246 ) that rotates with the drum portion about the axis of rotation. A fiber optic cable ( 40 ) is coiled on the drum portion. A fiber optic adapter ( 164, 264 ) and a connectorized pigtail ( 160, 260 ) are carried with the flange and positioned within the housing. The spool arrangement ( 136, 236 ) rotates relative to the housing when the fiber optic cable ( 40 ) is paid out. The drum portion ( 142, 242 ) can be removed from the flange after the fiber optic cable has been paid out to provide the distribution terminal with a compact configuration.

First claim

What is claimed is:

1. A fiber distribution terminal comprising:
a housing, the housing including an intermediate housing body defining a rear wall, a front cover cooperating with the intermediate housing body to define a front compartment and a rear cover cooperating with the intermediate housing body to define a rear compartment;
a spool arrangement that can rotate relative to the housing about an axis of rotation, the spool arrangement including a drum portion centered on the axis of rotation and a flange that rotates with the drum portion about the axis of rotation;
a fiber optic adapter carried with the flange and positioned within the housing, the fiber optic adapter including first and second ports;
a connectorized pigtail carried with the flange and positioned within the housing;
a fiber optic cable coiled on the drum portion of the spool arrangement and optically connected to the connectorized pigtail; and
wherein the spool arrangement rotates relative to the housing when the fiber optic cable is paid out, and wherein the drum portion can be removed from the flange after the fiber optic cable has been paid out to provide the fiber distribution terminal with a compact configuration, wherein the rear cover is removed from the intermediate housing body to provide the fiber distribution terminal with the compact configuration.

2. The fiber distribution terminal of claim 1 , wherein the flange is positioned in the front compartment and the coiled fiber optic cable is positioned in the rear compartment.

3. The fiber distribution terminal of claim 2 , wherein a majority of the drum portion is contained in the rear compartment.

4. The fiber distribution terminal of claim 2 , wherein the rear wall of the intermediate housing body defines an opening through which a portion of the drum portion extends.

5. The distribution terminal of claim 1 , wherein the flange forms a fiber management tray including at least one fiber routing path.

6. The distribution terminal of claim 5 , further comprising an optical splitter disposed in the fiber management tray.

7. The distribution terminal of claim 5 , further comprising a fanout disposed in the fiber management tray.

8. The distribution terminal of claim 1 , wherein the spool arrangement includes a second flange that is spaced along the drum portion from the flange.

9. The distribution terminal of claim 8 , wherein the second flange is configured to be removed with the drum portion.

10. The distribution terminal of claim 9 , wherein the drum portion is coupled to the flange by a snap-fit connection.

11. The distribution terminal of claim 1 , wherein a plurality of fiber optic adapters are carried with the flange and positioned within the housing, the fiber optic adapters of the plurality each including first and second ports.

12. A method of deploying a fiber distribution terminal, the fiber distribution terminal including a spool arrangement coupled to a housing, the housing including an intermediate housing body defining a rear wall, a front cover cooperating with the intermediate housing body to define a front compartment and a rear cover cooperating with the intermediate housing body to define a rear compartment, the spool arrangement including a drum portion, the method comprising:
paying off a fiber optic cable from the spool arrangement by pulling on a first end of the fiber optic cable to rotate the spool arrangement and at least one adapter carried therewith;
detaching the drum portion from the housing by removing the rear cover from the intermediate housing body while any excess cable remains coiled on the drum portion to form a compact terminal; and
mounting the compact terminal at a mounting location.

13. The method of claim 12 , wherein the drum portion and a rear flange are detached from the housing as a unit while a front flange of the spool arrangement remains attached to the housing.

14. The method of claim 12 , further comprising mounting the drum portion and any excess cable to a second mounting location spaced from the first mounting location.

15. A fiber distribution terminal comprising:
a housing, the housing including an intermediate housing body defining a rear wall, a front cover cooperating with the intermediate housing body to define a front compartment and a rear cover cooperating with the intermediate housing body to define a rear compartment;
a spool arrangement that can rotate relative to the housing about an axis of rotation, the spool arrangement including a drum portion centered on the axis of rotation and a flange that rotates with the drum portion about the axis of rotation;
a plurality of fiber optic adapters, carried with the flange and positioned within the housing, the fiber optic adapters each including first and second ports;
connectorized pigtails carried with the flange and positioned within the housing;
a fiber optic cable coiled on the drum portion of the spool arrangement and optically connected to the connectorized pigtails through an optical splitter carried with the spool arrangement, the optical splitter having at least a 4 to 1 split ratio; and
wherein the spool arrangement rotates relative to the housing when the fiber optic cable is paid out, wherein the rear cover is removed from the intermediate housing body to provide the fiber distribution terminal with a compact configuration.
