by the following statement:-
This invention relates to the splicing or optical joining of several optical fibers of a first group to corresponding fibers of a second group.
With the introduction of optical fibers into the communications network, particularly the outside cable plant, a critical need for accurate, reliable, easy-to-use splicing hardware has arisen Accuracy in this context entails basically the precise axial alignment and end abutment of corresponding fibers Realiability includes the permanence of the splice once effected and the repeatability from splice to splice of the desired high-level of optical coupling between corresponding fibers Ease of use involves effecting gang splices in the field using a minimum of steps, each simple and requiring no great dexterity.
Splicing hardware to achieve the foregoing, must accommodate optical fibers contained within a series of stacked ribbon structures, since the ribbon stack is preferred as a multifiber unit The ribbons contain a number, for example 12, of equally spaced, parallel fibers.
The ribbons of a stack must be capable of being fanned out and selectively connected to other ribbon structures Additionally, there is need for both a rearrangeable splice and a permanent splice in the joining of optical fiber ribbons or cables made up of a plurality of ribbons.
According to the present invention there is provided apparatus for interconnecting linear arrays of optical fibers, said apparatus comprising at least one substrate each with a channel extending longitudinally within one surface thereof, a surface with a plurality of grooves therein located within and extending along each channel, at least one member associated with a respective substrate and having a part shaped to extend within the channel, a surface of the said part being parallel to the grooved surface and serving to retain fibers within the grooves, and means for maintaining the substrate and member together.
A fiber optic ribbon cartridge connector has been devised which fulfills the foregoing needs The connector proper consists of a substrate with fiber-receiving grooves, and a mating member of cover Two fiber ribbons to be spliced are each mounted within a separate such connector Pursuant to one embodiment of the invention these connectors are placed in a body or cartridge where they fit snuggly against reference surfaces The two assemblies are abutted within the cartridge, placing the respective mating pairs of fiber ends into axial alignment The connectors are maintained in alignment and abutment within the cartridge by a tight fit of the connectors in the cartridge or by set screws of the equivalent Cartridge end caps advantageously are used in the tight fitting design as an aid in maintaining connector alignment; they may be used in either version to provide strain relief for the fiber splice joint.
The fiber-receiving channel of the substrate is offset to one side of the vertical center plane of the substrate to prevent tolerance build-up which can result in fiber misalignment The transverse alignment of two connectors within the cartridge body is achieved by registration of two converging planar bottom surfaces of the connector body with matching V-shaped floor planes of the cartridge body which act as reference surfaces In one embodiment, a tight or essentially zero clearance fit obtains between the top surface of the cover and the roof of the cartridge body, requiring relatively precise dimensional control of these components In a further embodiment, dimensional control may be somewhat relaxed by the provision of a PATENT SPECIFICATION
N 1cl ( 11) 1 586263 1,586,263 clearance zone between the roof of the cartridge body and top of the connector cover.
In this instance, securing means such as set screws assure that the V-shaped reference surfaces of the connector substrate are in registration with the corresponding surfaces of the cartridge body.
There is provided in one embodiment, a fixture for receiving a number of assembled optical fiber ribbon cartridges in spaced relation A rearrangeable splice of all corresponding ribbons between a first and a second cable is thereby conveniently achieved.
With reference to the accompanying drawings, Fig 1 is an exploded assembly view of an optical fiber connector embodiment of the invention; Fig 2 A and Fig 2 B are schematic sectional side views showing two versions of the optical fiber connector, one a tight fit and the other a loose fit; Fig 2 C shows schematically an alternative end identification means; Fig 3 is a partial schematic frontal view of a fiber-receiving substrate; Fig 4 is a frontal perspective view showing in exploded form an optical fiber connector comprising a cover and a substrate; Fig 5 is a side perspective view showing a further embodiment of the fiber-receiving substrate and mating cover, in which the grooves are formed by etching of a silicon chip; Fig 6 is a frontal schematic perspective view showing a connector cartridge holding fixture; Fig 7 is a frontal schematic diagram depicting a connector body adapted to receive in a rectangular chamber a like-shaped two-piece optical fiber connector; Fig 8 shows a variant on the subject matter of Fig 5; Fig 9 is a side view in partial section showing two optical fiber connectors assembled in end-abutting relation in a cartridge body; and Fig 10 is a partial end sectional view showing fibers located in the receiving grooves of a substrate of Fig 2 B with the cover plate in place.
Fig 1 depicts hardware pursuant to one inventive embodiment which achieves a reenterable optical fiber ribbon splice The numeral 10 denotes an optical fiber ribbon connector consisting of a fiber-receiving substrate 11, a substrate cover 12, a chambered cartridge 13 which receives two substratecover assemblies to be mated, and two end caps 14 Substrate 11 comprises a longitudinally extending channel 15 including a number of V-shaped parallel fiber-receiving grooves 17, and two planar bottom surfaces 20, 21, disposed at an angle denoted a to each other.
The grooved channel 15 is intentionally not centered with respect to the plane 16 which bisects the angle a, but instead is offset a visible amount to one side or the other of plane 16 The visible offset ‘provides one means for separately identifying the substrate 70 ends Thus, in plan view, the substrate 11 illustrated in Fig 2 A is seen to have its channel 15 offset toward the right of plane 16, in which orientation of lower substrate end lla is distinguishable from upper substrate 75 end lib.
The desirability of making such distinction lies in the fact that any constant inaccurancy in the transverse location of grooved channel in a batch of substrates 11 will be effectively 80 doubled if the improper ends of two substrates are abutted As a result any two fibers in corresponding grooves will be axially misaligned by twice the amount of transverse inaccuracy, causing optical energy loss at 85 such a splice These losses are cumulative in a series connection of several such transversely misaligned fibers But by following a system of always matching an “a” end to a “b” end in the splicing operation, any constant transverse 90 location inaccuracy is cancelled.
The offset grooved channel 15 is one means of providing the coding to identify the ends.
Other means, for example, including alignment marks on the side of all substrates such 95 as the arrows 35 of Fig 2 C, can be envisioned for achieving the same end The grooves 17 are of such depth and angularity that, as shown in Fig 10, when optical fibers 18 are placed therein, the fiber tops are approxi 100 mately even with or slightly above the apexes formed by adjacent grooves The ridge or extension 19, which extends from cover 12 to mate with the substrate channel 15, touches the fibers 18 105 In one embodiment shown in Fig 2 A the substrate 11 and cover 12 when assembled exhibit from zero clearance to an interference fit with respect to the reference surfaces 22, 23, 24 of the cartridge 13 In a further embodi 110 ment portrayed in Fig 2 B a slight clearance is provided between the ceiling 24 and the top of cover 12 In both options, as seen in Figs 2 A and 2 B a clearance is provided between the sides 26, 27 of the cartridge 13 115 and the corresponding sides of the substratecover assembly To set the substrate reference surfaces 20, 21 firmly against the cartridge reference surfaces 22, 23, in the loose fit options, set screws 28 mounted in machine 120 thread holes 29 of the cartridge 13, are engaged to force the top 25 of the cover 12 downwardly.
The outer surface of cartridge 13 advantageously is cylindrical, but the ends are 125 reduced in diameter at location 30 and then provided with a bevel 31 Cap 14 as seen in partial cross-section in Fig I has the same outside diameter as does cartridge 13 and in addition is provided with an interior bevel, 130 1,586,263 corresponding to bevel 31 of the cartridge.
The end caps 14 have a central orifice 32 through which an optical fiber ribbon 33 is mounted.
Advantageously, each of these parts so far described are fabricated by injection molding to ensure achievement of required tight tolerances The planar reference surfaces 20, 21 of substrate 11, for example, must be highly flat and disposed at the same V-angle with respect to each other as are the reference surfaces 22, 23, of cartridge 13 with which they mate.
Use of the optical fiber connector depicted in Fig 1 requires that the enveloping ribbon structure be stripped back to expose the parallel fibers 18 at their ends The fibers are then placed in receiving grooves 17 such that their ends are roughly coincident with the end 34 of the substrate 11 as depicted in Fig.
3 The cover 12 is then applied, producing the end configuration depicted in Fig 10 As a final step, the cover-substrate assembly is cemented together and given an end polish rendering the end surface, including the fiber ends, optically flat An alternative end preparation occasionally preferable to polishing is to cut the fiber ends prior to assembly and then to assemble them with the cut ends in the same plane as the connector end.
Similar preparation is given to a second substrate, cover, and fiber ribbon assembly.
These two assemblies are then inserted into the cartridge 13 until they abut as shown in Fig 9 Refractive index matching material may be added through orifice 13 a If the configuration is a tight fit as described above, no set screws are required; otherwise the set screws are engaged Finally, the end caps 14 are added and secured lightly with cement if desired.
The foregoing describes a re-enterable splice in that the two cover assemblies which are joined in an optical connection may be disconnected and reconnected elsewhere.
In a further embodiment of the invention a connection such as depicted in Fig 4 may be used to achieve a permanent splice In this embodiment a substrate 41 is provided with continuous grooves A mating cover 42 holds fibers in position in the respective grooves.
In this case the grooves are continuous along the length of the substrate 41 and contain the two ends of the ribbons to be connected The sides 43 of the groove channel in substrate 41 may be tapered outwardly to match an inward taper of the sides 44 of the insert of cover 42.
Preparation of the ribbons for use in this splice requires that the ribbon ends be carefully squared so that they all abut at the same time Once this connector is assembled it may be permanently glued Since these do not require a body such as cartridge 13 for alignment, the assembled connector depicted in Fig 4 may be used by itself or housed in a 65 loose fitting body, not shown.
Fig 5 illustrates a variation of the Fig 4 permanent splice comprising substrate 51 and cover 52 in which the parallel fiber-receiving grooves are formed on a separate insert 53 70 Highly precise dimensional control of the groove geometry may be achieved by fabricating the insert 53 of an etchable material such as silicon and etching the grooves by well-known processes The insert 53 fits in a 75 channel 54 of the substrate Fibers are prepared as in the Fig 4 embodiment and placed with abutting alignment in the grooves of insert 53 Advantageously, although not necessarily, the fibers fit into the insert 80 grooves so that the fiber tops are at the same height as the apexes which separate the grooves The cover 52 includes two extenders which may be compliant, and which engage the fibers to serve them in abutting positions 85 Index matching material may be supplied through passage 56 and thereafter the cover 52 and substrate 51 are permanently cemented together.
Fig 6 illustrates a holder for assembled 90 connector cartridges The holder consists of several stacked modules 61 each formed on top and bottom with plural side-by-side semicylindrical chambers 60 for receiving cartridges of rearrangeable splicing hardware 95 as illustrated in Fig 1 The end members 63 of the holder are essentially two halves of one of the modules 61 Ribbon entrance corridors 64 connect the chambers 62 to the holder exterior The modules 61 and end members 100 63 are secured by any convenient means such as pinning or a tack glue Aligning of adjacent modules is provided by the fit of the cartridges in the adjacent semicylindrical chambers 60 105 The holder will accommodate a number, for example, twelve of connector cartridges.
A typical number of fibers per ribbon is also twelve; and thus, 144 fibers of a first optical fiber cable 70 may be joined in the holder to 110 144 fibers of a second optical cable 80 Since the splices may be rearrangeable, any one fiber ribbon of the cable 70 may be selectively spliced to any of the fiber ribbons of the second cable Also, if desired, pairs of ribbons 115 from one cable may be spliced together in the apparatus shown by looping one of the ribbons around the far side of the holder The use of end caps on the cartridge when housing them in the holder is optional, since the con 120 nector assembly is held in the cartridge by the holder wall adjacent the corridor 64.
Fig 7 illustrates a further variation of cartridge connection in which the cartridge 90 includes a rectangular slot Since a modest 125 interference fit between the connector 91 is contemplated, dimensional control must be carefully maintained within tight tolerances.
This embodiment also uses the offset grooved 1,586,263 chamber in the substrate 92 as one means of identifying connector ends.
The embodiment portrayed in Fig 8 is similar in function to that of Fig 5 in that a substrate 100 receives a grooved chip 101 in a channel 102 A cover 103 has a body portion 104 that fits into the channel 102, and extending end portions 105 which capture the fiber ribbon exterior at the entrances 106 to provide strain relief.
