Abstract
Abstract The present invention relates to a housing for an optical coupler. The housing includes a primary protective body having a receiving space therein, wherein the coupled portion of the coupler is positioned. A support material at least partially about the coupled portion of the coupler extends in the receiving space to the primary protective body. The support material is resilient and has an index of refraction less than that of the coupled portion of the coupler.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
139 words
A housing for an optical fiber directional coupler formed of a plurality of optical fibers having a coupled portion at which electromagnetic waves can be coupled therebetween and at least one excess portion of an optical fiber extending beyond said coupled portion, said housing comprising: a primary protective body having a receiving space therein and having a slot means therein providing access to said receiving space from outside, said receiving space extending into said primary protective body past said slot, said coupled portion of a said coupler to be housed being positioned in said receiving space; and a support material at least partially about said coupled portion of said coupler and extending in said receiving space to said primary protective body, said support material being resilient and having an index of refraction less than that of said coupled portion.
Claim 2
Dependent Claim
139 words
A housing for an optical fiber directional coupler formed of a plurality of optical fibers having a coupled portion at which electromagnetic waves can be coupled therebetween and at least one excess portion of an optical fiber extending beyond said coupled portion, said housing comprising: a primary protective body having a receiving space therein and having a slot means therein providing access to said receiving space from outside, said receiving space extending into said primary protective body past said slot, said coupled portion of a said coupler to be housed being positioned in said receiving space; and a support material at least partially about said coupled portion of said coupler and extending in said receiving space to said primary protective body, said support material being resilient and having an index of refraction less than that of said coupled portion.
Claim 3
Dependent Claim
54 words
The apparatus of claim 1 further comprising a suspension means to fixedly hold a part of said excess portion in said receiving space near a location where said excess portion emerges from said primary protective body, said suspension means being positioned between said location of emergence of said excess portion and said support material.
Claim 4
Dependent Claim
13 words
The apparatus of claim 2 wherein said suspension means comprises an epoxy adhesive.
Claim 5
Dependent Claim
15 words
The apparatus of claim 1 wherein the primary protective body comprises a quartz glass tube.
Claim 6
Dependent Claim
20 words
The apparatus of claim 4 wherein said slot means comprises a wall portion removed between opposite ends of said tube.
Claim 7
Dependent Claim
17 words
The apparatus of claim 1 wherein said support material substantially fills said receiving space surrounding said coupler.
Claim 8
Dependent Claim
13 words
The apparatus of claim 1 wherein said support material comprises a silicone material.
Claim 9
Dependent Claim
44 words
The apparatus of claim 1 further comprising a secondary protective body having a cavity therein and having an opening therein providing access to said cavity from outside, said primary protective body being positioned in said cavity to cover at least in part said slot.
Claim 10
Dependent Claim
21 words
The apparatus of claim 8 further comprising a securing means to attach said secondary protective body to said primary protective body.
Claim 11
Dependent Claim
14 words
The apparatus of claim 9 wherein said secondary protective body comprises a metal tube.
Claim 12
Dependent Claim
24 words
The apparatus of claim 10 wherein the securing means comprises a silicone adhesive positioned between said primary protective body and said secondary protective body.
Claim 13
Dependent Claim
14 words
The apparatus of claim 11 wherein said optical fibers have a protective jacket thereon.
Claim 14
Dependent Claim
22 words
The apparatus of claim 12 wherein a portion of the protective jacket is removed from said optical fibers forming a jacketless region.
Claim 15
Dependent Claim
19 words
The apparatus of claim 13 wherein said jacketless region of at least two optical fibers have a coupled portion.
Claim 16
Dependent Claim
28 words
The apparatus of claim 14 wherein said coupled portion has a first excess portion and a second excess portion of optical fiber oppositely extending beyond said coupled portion.
Claim 17
Dependent Claim
77 words
The apparatus of claim 15 further comprising a suspension means to fixedly hold a part of said first excess portion near a first location where first excess portion emerges from said primary protective body, and to fixedly hold a part of said second excess portion near a second location where said second excess portion emerges from said primary protective body, capable of suspending said coupled portion, prohibiting contact between said coupled portion and said primary protective body.
Claim 18
Dependent Claim
13 words
The apparatus of claim 16 wherein said suspension means comprises an epoxy adhesive.
