Technical Field
[0001] The present invention relates generally to provision of optical fiber telecommunications
service. More specifically, the present invention relates to a device and method for
blocking a connection between a customer and optical fiber services.
Background
[0002] As demand for telecommunications services increases, optical fiber services are being
extended into more and more areas. Often, it is more cost effective to provide for
greater service capacity than current demand warrants. This will allow a telecommunications
service provider to quickly and cost-effectively respond to future growth in demand.
Optical fiber cables may be extended to a customer's premises prior to that customer
actually requesting or needing service. Such cables may be extended to premises adjacent
the premises of a current customer, as it may be cost effective to extend both cables
at the same time, or the cables may be extended to new building sites in anticipation
of the new occupants of those sites requesting fiber optic service.
[0003] When cables are extended in anticipation of future service expansion, it is desirable
to provide for blocking illumination of the future customers drop cable prior to that
customer requesting the service. Document
EPO967497 discloses an attenuator with a first end configured to be received within a fiber
optic adapter and a second end configured to fit about a ferrule of a fiber optic
connector.
Summary
[0004] The present invention relates to a service blocking device with a body including
a first end and a second end. The first end is configured to be received within an
opening of a fiber optic adapter. The second end includes an opening configured to
fit about a ferrule of a fiber optic connector, the fiber optic connector configured
to be received within the opening of the fiber optic adapter. The body is configured
so that the fiber optic connector is held generally coaxially aligned with the opening
of the adapter when the first end of the body is within the opening of the adapter
and the second end of the body is positioned about the ferrule of the fiber optic
connector. The body including an intermediate bulkhead between the first end and the
second end to prevent light from passing through the body from the terminal end of
the fiber optic cable through the second end of the adapter.
[0005] The present invention further relates to connecting a customer drop cable to a fiber
distribution cable by removing a service blocker from an adapter between the two cables
and preventing connection of a customer drop cable to a fiber distribution cable by
inserting a service blocker into an adapter between the cables, according to claims
13 and 14.

Detailed Description
[0007] Reference will now be made in detail to the exemplary aspects of the present invention
that are illustrated in the accompanying drawings. Wherever possible, the same reference
numbers will be used throughout the drawings to refer to the same or like parts.
[0008] FIG. 1 illustrates a sliding adapter pack 10 including a three fiber optic adapters
12 mounted in a sliding frame 13. Adapter packs such as theses shown in commonly owned
U.S. Patents Nos. 5,504,988 and
6, 438, 310. However the adapters may be mounted or held, such as mounted to a bulkhead, a panel,
within a drawer, or other piece of equipment, the discussion below regarding fiber
optic cables, connectors and adapters is generally applicable. While FIG. 1 illustrates
adapters 12 mounted within sliding pack 10, adapters 12 could be mounted in a variety
of other settings, either alone, in combination with each other, or in conjunction
a plurality of other adapters 12. Adapters 12 align fiber optic connectors, such as
connectors 16, which terminate fiber optic cables, such as cables 14, to permit optical
signals to be transmitted from one cable 14 to another cable 14, such as shown in
the lowest positioned adapter 12 in sliding frame 13. Adapter 12 includes a first
end 18 and a second opposing end 20 for receiving connectors 16. As shown, both ends
of adapter 12 are adapted to receive and optically connect connectors 16 which conform
to a known SC format. Alternatively, adapters 12 may be configured to receive and
optically connect connectors 16 that conform to other formats and styles.
[0009] As shown in FIG. 1, one of the connectors 16 is inserted within first end 18 of the
top most adapter 12 and an adapter dust cap 22 is inserted within second end 20 of
that adapter 12. Adapter dust cap 22 fits closely within one of the openings 18 and
20 to provide a seal against intrusion of dust or other contaminants into adapter
12. As shown in the lower most adapter 12, another connector 16 terminating another
cable 14 could be inserted within second end 20 of the same adapter 12 so that the
two cables 14 could be optically connected. The upper and lower adapters in FIG. 1
illustrate those connection or disconnection arrangements of connectors that are currently
used in the telecommunications industry.
[0010] The cable/adapter arrangement shown in the lowest position in FIG. 1 is well known
in the telecommunications industry and permits, for example, customer service or drop
cables to be connected to fiber optic distribution cables to provide fiber optic service
to a customer. However, when a customer drop cable has been extended to a customer
premises prior to and in anticipation of that customer requesting the service, it
is desirable that the optical path between the two cables 14 be broken. One current
method of breaking the optical path is illustrated in the top most position in FIG.
1, where one of the cables 14 is removed from the adapter 12 and adapter dust cap
22 inserted in its place. The removed cable 14 is then stored somewhere else within
the installation in anticipation of connecting the two cables at the top most adapter
12. It is also desirable to have the two cables 14 positioned as closely as possible
to each other so that turning on service to the customer upon request is simple and
efficient. Since some installations of connection locations include a large number
of adapters 12, it is desirable that those connections between cables which have been
interrupted be quickly visible to a field technician.
[0011] Between the connector 16 and adapter 12 in the middle position of sliding frame 13,
a service blocking device 100 is positioned. Service blocking device 100 maintains
the connector 16 generally in alignment with adapter 12, but interrupts the optical
path from the terminal end of cable 14 held by connector 16. As can be seen from FIG.
1, device 100 provides an offset mounted of connector 16 to adapter 12, making the
location of connectors where service has been interrupted fairly obvious, even in
a crowded enclosure. Device 100 may also have an exterior color which is distinct
from other colors found adjacent adapters 12 and distinct from the connectors 16 and
cables 14. This will further assist in a quick visual indication of which circuits
include devices 100 when a technician accesses a service panel.
[0012] It is desirable that adapters 12 might be installed in a factory pre-wired panel
with cables 14 extending to both sides of adapters 12 and service blocking devices
100 in place between cables and cables 14 on one side of the panel. The panel could
then be installed in the field as needed without cable re-routing within the panel
required by the installer. This similar in nature to the parking lot concept incorporated
in commonly owned U.S. Patent Application
US 2005 281526. In such a parking lot configuration, normally one side of installed adapters 12
be fully populated with cables 14, such as shown on the left side of sliding frame
13 of FIG. 1.
[0013] Referring now to FIG. 2, connector 16 is shown with a known connector dust cap 26
positioned about a ferrule 28 held by connector 16. The terminal end of the optical
fiber within cable 14 is held by ferrule 28. Connector dust cap 26 fits tightly about
ferrule 28 to protect the terminal end from dust or other contaminants when connector
16 is not in use transmitting optical signals. Connector dust cap 26, as shown in
FIG. 3, includes an enlarged end 30 to permit grasping of dust cap 26 to remove it
from ferrule 28 of connector 16, and an opening 34 at an opposite end 32. Opening
34 is sized to receive and closely fit about ferrule 28 of connector 16. As shown,
connector dust cap 26 is often made of a clear pliable material and its size will
not permit it to be received within either opening 18 or 20 of adapter 12. Connector
16 also includes a keying feature 36, which engages a mating recess or slot of adapter
12 to ensure that connector 16 is inserted within adapter 12 is the correct orientation.
[0014] FIG. 4 shows connector 16 with service blocking device 100 mounted about ferrule
28. Service blocking device 100 includes a body 106 with a first end 102 configured
similar to adapter dust cap 22 for being received with one of the ends 18 and 20 of
adapter 12, and a second opposing end 104 sized to receive and fit closely about ferrule
28. First end 102 of service blocking device 100 acts as a dust cap to seal one of
the openings 18 and 20 of adapter 12, similar to adapter dust cap 22. Second end 104
of service blocking device 100 acts as a dust cap for ferrule 28 and the terminal
end of the optical fiber of cable 14 held by ferrule 28, similar to connector dust
cap 26. Body 106 is made of a material preferably sufficiently pliable to permit deforming
to achieve an adequate seal of either ferrule 28 or either adapter end 18 and 20.
Body 106 includes intermediate bulkhead 114 of body 106 which may be sized and shaped
to closely match the size and shape of the opening in either first end 18 or second
end 20 of adapter 12. Intermediate bulkhead 114 extends across the light path between
first end 102 and second end 104 and prevent passage of light signals through body
106 between the ends 102 and 104.
[0015] Body 106 may also include a keying feature 110 which engages a recess or slot of
adapter 12 to properly orient first end 102 within adapter 12. Orientation of device
100 in adapter 12 helps ensure that extension 112 of first end 102 will mate with
and provide a contamination seal about a split sleeve or other ferrule alignment feature
within adapter 12. It is also anticipated that body 106 could be configured without
such a keying feature 110.
[0016] Referring now to FIGS. 7 and 8, an alternative embodiment of a service blocking device
200 is shown. Device 200 includes a body 206 with a first end 202 and a second end
204. Second end 204 defines an opening 208 to receive connector 16. An alignment slot
212 in one side of opening 208 engages keying feature 36. Body 206 may also include
an optional keying feature 210 adjacent first end 202 to engage a recess or slot in
adapter 12. First end 202 further defines an opening 214 to permit a split sleeve
or other ferrule alignment feature within adapter 12 to be received within body 206.
Between first end 202 and second end 204, within body 206 is an optically opaque element
which prevents light or optical signals from passing through service blocker device
200. Body 206 does not define a continuous light path between first end 202 and second
end 204.
[0017] Body 206 also includes a first portion 216 adjacent first end 202 and a second portion
218 adjacent second end 204. First portion 216 is sized to fit within one of the ends
18 or 20 of adapter 12 and extend deep enough into adapter 12 so that opening 214
fits about and provides a seal from dust or other contamination about the ferrule
alignment feature within adapter 12. Second portion 218 is sized to permit opening
208 to be large enough to accommodate a connector 16 but not so large as to interfere
with connectors inserted within adjacently positioned adapters 12. Second portion
218 extends beyond the end of adapter 12 and offsets connector 16 away from adapter
12 to provide a quick visual indication of the position of service blocking device
200.
[0018] With reference to both bodies 106 and 206, it is desirable that at least a portion
of the bodies extends outside of adapter 12 between adapter 12 and connector 16 to
aid in the dissipation of any heat built up within the bodies. The optical signals
whose passage through bodies 106 and 206 are being blocked are typically in the form
of modulated laser light. Laser light, particularly at higher levels of energy that
are being increasingly used in telecommunications, may cause a heat built up with
bodies 106 and 206 as signals passing through cable 14 are blocked. This heat build
up needs to be dissipated to prevent damage to cable 14, connector 16, ferrule 28
or adapter 12, or other equipment. By having at least a portion 116 of each body 106
(as shown in FIG. 1) or portion 218 of body 206 outside of adapter 12, the heat built
up within the bodies may be more easily dissipated, as opposed to being confined within
adapter 12. Additionally, at least these portions 116 and 218 of bodies 106 and 206,
respectively, may be made of a material chosen for heat transmissive, or optical energy
absorption or reflection qualities. These colors of the materials of devices 100 and
200 may also be selected to improve contrast with the other colors adjacent adapters
12, connectors 16 and cables 14 to improve the visual identification of circuits including
devices 100 or 200.
[0019] FIG. 9 shows a bulkhead 300, such as might be included in a fiber optic module or
panel, through which a plurality of fiber optic adapters 12 extend. First end 18 and
second end 20 of adapters 12 are on opposite side of bulkhead 300. Cables 14 with
connectors 16 extend to either end 18 or 20 of adapters 12. In some adapters 12, service
blocking devices 200 are positioned between connector 16 of cable 14 and an opening
in first end 18 of adapter 12. Another connector 16 of a corresponding cable 14 is
inserted directly within the opposite end 20 of adapter 12. In other adapters 12,
connectors 16 of cables 14 are inserted directly into both ends 18 and 20. Service
blocking devices 200 position the inserted connectors 16 and cables 14 offset from
the adapters, making these blocked cables easy to spot in the field by service personnel
visiting the installation where bulkhead 300 is mounted.
[0020] Devices 100 and 200 may be releasably held with one of the ends 18 or 20 of adapter
12 by a friction fit or by a releasable mechanism, such as catch 38, included in connector
16 (shown in FIG. 4). Devices 100 and 200 may also include a friction fit or mating
structure which mates with catch 38 for releasably holding connector 16. FIG. 10 illustrates
a partial cross-sectional view of first end 202 of an alternative embodiment device
220 showing additional detail of catch 38. FIG. 10 also shows a partial cross-sectional
view of second end 204 of device 220 with a mating structure 70. It is anticipated
that ends 18 and 20 of adapter 12 may also include mating structures 70. Catch 38
of device 220 includes a recess 72 and a sliding portion 74. When first end 202 is
inserted within adapter 12, a catch 76 on a distal end 78 of mating structure 70 engages
recess 72 on either side of first end 202. The engagement of catches 76 and recesses
72 on opposite sides of first end 202 cooperate to hold device 220 within adapter
12.
[0021] To remove device 220 from adapter 12, a technician would grasp body 206 of which
sliding portion 74 is an integral part, and pull body 206 away from adapter 12. Doing
so will cause sliding portion 74 to translate relative to recess 72 so that tapered
leading edge 80 engages catches 76 and urges them outward from recesses 72, deflecting
mating structure 70. Once mating structure 70 has been sufficiently deflected outward,
first end 202 of device 220 may be removed from adapter 12. Catch 38 of connector
16 is similarly configured to permit insertion within second end 204 of device 220
and engagement of mating structure 70 and subsequent disengagement of mating structure
70 and removal of connector 16 from second end 204.
[0022] It is anticipated that devices 100, 200 and 220 may be made of a relatively inexpensive
and disposable material and that the devices may be simply discarded once they have
been removed from an adapter in the field.
