Referring to Fig. 8, closed polishing chuck 6 has the optical fiber holder 172 in the slotting cave 38 of the socket optical fiber holder that is driven integratedly and remain between base 30 and the top cover 32, and this polishing chuck 6 is positioned at the guide rail 16 of device pedestal 4.The edge of facet 40/50 is assemblied in the guide rail 16, and allows the length direction slip along the groove 10 of device pedestal 4 guide rail 16 in of polishing chuck 6.Arrow A represents to polish the glide direction of chuck 6 in groove 10 among Fig. 8, and this slip is to carve and fracture optical fiber 178 and 180 in order to draw, to continue the preparation of end face and connector assembly.
Referring to Fig. 9 A-C and in conjunction with Fig. 8, in these figure, polishing chuck 6 is in several diverse locations of drawing in the quarter and the process that fractures.In Fig. 9 A, be positioned at guide rail 16 and will polish chuck 6 insertion grooves 10 by the edge that makes facet 40/50.When initial insertion groove 10, optical fiber 178 and 180 (only show optical fiber 178 among the figure, but should be appreciated that, optical fiber 180 just in time behind at optical fiber 178, thereby on the such end view drawing of Fig. 9 A-C, be invisible) straight line extends downwards in groove 10 basically.Shown in Fig. 9 B, along with polishing chuck 6 slides along guide rail 16 on direction shown in the arrow A, optical fiber 178 contacts with bending part 18.The optical fiber 178 that stretches out from polishing chuck 6 is bent by bending part 18.Shown in Fig. 9 C, along with polishing chuck 6 continues to move along guide rail 16 on the arrow A direction, the pointed edge 20a of scriber 20 with contact with it from the position that facet 40/50 stretches out at optical fiber 178.When contacting with optical fiber 178, pointed edge 20a forms cut channel in the periphery of optical fiber 178 under the effect of the folding s tress that is provided by bending part 18.The cut channel that folding s tress connection forms with the pointed edge 20a of scriber 20 together, when optical fiber 178 just when facet 40/50 stretches out, for example optical fiber 178 has just stretched out about 10 μ m to 250 μ m (promptly being approximately the twice of fibre diameter) and just it has been fractureed.
To this, the end face characteristic of optical fiber once preferably is discussed briefly is connected, so that more be expressly understood the advantage that end face prepares and connector is assembled of utilizing fiber end face preparation of the present invention and 2 of connector apparatus for assembling to realize with effective optical fiber.Usually, optical fiber is connected, it is very important having four parameters at least.They are fiber end face angle, flatness, surface quality and position.End plane angle for the contact of fiber end face and fiber end face or with being connected of optical devices be very important.Flatness is meant plane or nonplanar shape of fiber end face.For fiber end face and fiber end face or with being connected of device, pass through the correct transmission of contact in order to realize light, consistent flatness (no matter whether plane) is very important.The end face quality is meant the characteristic of the glass surface of fiber end face.For correct connection, wish to have smooth, not coarse end face surface.Therefore, to make the surface of end face become smooth the fiber end face polishing usually.Another important parameters is an endface position, and this is meant from the distance of the reference position, center to of a fiber core, for example, under the situation of connector body shown in Figure 5 114, just is meant the distance that fiber end face extends from optical fiber holder 172.In the present technique field, endface position is meant " intercepted length " under the splicing situation sometimes, promptly prepares one section exposed optical fiber by fibre coating is stripped to fiber end face always.Because the most of joints of optical fibre require limited error, for making a plurality of fibre-optical splices of fibre-optical splice at same benchmark, endface position is preferably consistent.According to the preparation of the fiber end face of the embodiment of the invention and connector apparatus for assembling 2 each above-mentioned parameter is become one makes peace accurately, thereby very big advantage is arranged.
Referring to Figure 10, wherein show the situation that the optical fiber 178 and 180 that has fractureed is polished, the device pedestal 4 among this figure comprises facet 12.Facet 12 is the border circular areas that are coated with a grinding film.Facet 12 is positioned at the rear end of groove 10.Guide rail 16 continues up to its rear end along groove 10, and terminates in facet 12 places.Guide rail 16 extends to facet 12, thereby when polishing chuck 6 is mobile to the back-end along guide rail 16, can fall on the facet 12 after by guide rail 16.Polishing chuck 6 be by usually and the facet 40/50 of facet 12 planar alignment of device pedestal 4 be orientated.Polishing chuck 6 is can mat this to be oriented on the grinding film of facet 12 and to move.
The polishing of fiber end face is normally finished by the skilled craftsman, and they rule of thumb and by means of subjective " sensation " determine whether end face has obtained satisfactory polishing and handled.Millwork by facet 12 and polishing chuck 6 also can be determined by skilled worker's subjectivity to realize.Yet,, may give to a certain degree the objectivity of (even may be whole) for polishing technology because fiber end face prepares and the particular design of connector apparatus for assembling 2.For example, at four parameters of above discussion, the optical fiber that is undertaken by device pedestal 4 and polishing chuck 6 is drawn to carve and fracture and is operated in each drawing and carves and can obtain to draw uniformly basically to carve and the effect that fractures when fractureing.Owing to adopt fiber end face preparation and connector apparatus for assembling 2 can obtain to draw uniformly to carve and the effect that fractures, so needn't rely on skilled worker's subjective technical ability just can set up the process that can realize polishing uniformly basically effect.Similarly, as long as all adopt identical polishing process (for example specific polishing pattern, stroke and preload) at every turn, just can obtain best polishing effect and also be kept.Pattern can be for example circular, draw 8 words, linear or other.Every kind of pattern all there is " stroke " amount of a best, so that can be to the polishing effect that a certain specific drawing carved and the acquisition that fractures is expected.Preload is meant the power that applies, force fiber end face to contact with grinding film in the polishing process.Under the situation that adopts fiber end face preparation of the present invention and connector apparatus for assembling 2, in each polishing operation process, preload is consistent.
Particularly for adopting the preload of the optical fiber that preparation of this fiber end face and apparatus for assembling 2 polish, preload is owing to that section fiber lengths that stretches out from the facet 40/50 that polishes chuck 6 produces.Polishing chuck 6 can not keep the rigidity of optical fiber on facet 40/50, this is because of gapped between facet 40 and facet 50 and therebetween optical fiber.On the contrary, polishing chuck 6 can only be inserted the rigidity that optical fiber is located to keep in cave 38 (as shown in Figure 6) at the socket-type optical fiber holder by optical fiber holder 172 (as shown in Figure 6).So just allow optical fiber crooked on this segment length between optical fiber holder 172 and the fiber end face.The stress that causes owing to the bending of optical fiber trends towards with a constant relatively power end face being pushed the abrasive surface of grinding film.Handled toppedly on facet 12 time when polishing chuck 6, can ground off the glass fibre of fiber end face.Along with in the polishing process that glass fibre is worn from end face, the fiber lengths that stretches out from optical fiber holder 172 is shortened, degree of crook diminishes, up to no longer stretching out (promptly from the facet 40/50 of polishing chuck 6 when optical fiber, this fiber end face is in same plane with that facet 40/50 of contiguous facet 12) and bending stress when being released, it is straight that optical fiber becomes.
Certainly, polishing operation also can have various variations.For example, will not polish and be performed until fiber end face and no longer stretch out and be in the state of no bending stress from facet 40/50.In addition, the error of fiber end face angle depends on the size in the hole 54 of facet.The length breadth ratio in hole 54 is the ratio of the length (being the thickness of facet 40/50) of finger-hole 54 with respect to the lateral dimension (if hole 54 is that circular words are exactly its diameter) in hole 54.The numerical value of length breadth ratio can obtain more true with consistent end plane angle by polishing more greatly.In the possible structure of another kind, can optical fiber be remained on the facet 40/50 by a low hardness elastomer (for example being filled in the elastic body in the gap between optical fiber and the polishing face 54).So just can limit fibre possible moving in the hole 54 of facet.This elastic body can contact to realize polishing for optical fiber and abrasive substance provide pressure in the stretcher strain of optical fiber during by grinding film.In addition, facet 12 can move or facet 12 and 40/50 all can move with respect to facet 40/50, thereby realizes relatively moving.
Referring to Figure 11, wherein polish on the block projection 14 that chuck 6 is positioned at device pedestal 4 and be shown in an open position, so that the polishing end face of optical fiber 178 and 180 is checked and cleaned.Particularly from the Figure 11 that amplifies as can be seen, optical fiber 178 and 180 has been drawn in its end and has been carved, fractures and polish.Can see that optical fiber 178 and 180 end face tip 40a extend to facet 40.Should be appreciated that because the cause of this configuration, optical fiber 178 and 180 comprises that their end face all can check and clean.In Figure 11, it is further noted that sight glass mounting hole 41.
