Description

光纤连接器插芯及其制造方法、光纤连接器 The optical connector ferrule and a method for manufacturing an optical fiber connector

技术领域 FIELD

[0001 ]本发明涉及光纤连接器领域,尤其是光纤连接器插芯的制造方法。 [0001] The present invention relates to the field of optical fiber connectors, particularly in the manufacturing method of the optical connector ferrule.

背景技术 Background technique

[0002] 光纤连接器的插入损耗主要由连接器表面抛光质量和光纤纤芯的偏置决定。 [0002] The fiber optic connector insertion loss is mainly determined by the surface of the polishing bias the connector and the fiber core mass. 本发明主要关注于降低光纤纤芯的偏置。 The present invention focuses on reducing the fiber core offset. 互配连接器纤芯的偏置主要由以下三个因素决定:(I)连接器插芯内孔和连接器插芯外圆的偏心度el(参见图1A); (2)光纤纤芯和光纤包附层的偏心度e2(参见图1B); (3)光纤的直径和连接器插芯内孔直径的差异Ad(参见图1C)。 Bias interworking connector core is mainly determined by three factors: (I) connector ferrule connector ferrule bore and the eccentricity of the outer EL (see FIG. 1A); (2) and the fiber core eccentricity of the fiber cladding layer attached e2 (see FIG. 1B); (3) the diameter of the optical fiber connector ferrule and the inner diameter difference between the Ad (see FIG. 1C). 其中,光纤纤芯和光纤包附层的偏心度e2所对应的影响是最小的。 Wherein the corresponding effect of the fiber core and fiber cladding eccentricity e2 of the attachment layer is minimal.

[0003]目前,低损耗连接器制造主要通过采用高精度的连接器插芯和调芯来制造。 [0003] Currently, low loss connectors manufactured primarily manufactured by using the connector ferrule and a high-precision alignment. (I)采用高精度的连接器插芯,请参见图1A、图1B和图1C,通过减小连接器插芯内孔和连接器插芯外圆的偏心度(el)以及光纤的直径和连接器插芯内孔直径的差异(Ad)来降低光纤纤芯相对于连接器插芯外圆的偏置,但是会带来连接器插芯成本的急剧上升以及制造过程中光纤非常难以穿入连接器插芯内孔。 (I) a high-precision connector ferrule, see Figure 1A, 1B and 1C, the outer diameter of the ferrule by reducing the connector ferrule and the connector hole eccentricity (el) and the optical fiber, and connector ferrule hole diameter difference (Ad) to reduce the offset of the fiber core with respect to the outer connector ferrule, but the ferrule will bring a sharp rise in the cost of the connectors and the optical fiber manufacturing process is very difficult to penetrate connector ferrule hole. (2)采用调芯,请参见图2,即通过将连接器纤芯的偏置调整到对应于连接器键位03的特定角度范围(图2中的黑色扇形区域内),从而减小连接器互配时光纤纤芯的偏置,但是,只适用于经过调芯的连接器互配,如采用普通精度的连接器插芯,制造过程相当于筛选,如采用次高精度的连接器插芯,同样会存在连接器插芯成本的上升以及制造过程中光纤穿入连接器插芯内孔的难度上升。 (2) alignment, see Figure 2, i.e. by adjusting the bias to the core of the connector corresponding to the connector 03 of the keys a certain angular range (dark sector within the region in FIG. 2), thereby reducing the connection when Intermateability offset of the fiber core, however, only applies to the alignment of the connector via interworking, such as ordinary connector ferrule accuracy, the manufacturing process is equivalent to filtering, such as the use of high precision secondary connector ferrule , will also increase the difficulty of the presence of the ferrule and connector costs during manufacture the optical fiber connector ferrule penetrates the bore rises.

[0067] 第一实施例 [0067] First embodiment

[0068]下面参照图3至图9来说明根据本发明的第一实施例的制造光纤连接器插芯的方法。 [0068] Referring to Figures 3 to 9 will be described a method of manufacturing an optical fiber connector of the first embodiment of the present invention in accordance with the ferrule.

[0069]如图4所示,用固定装置200将连接器插芯100预先固定住,然后,利用摄像机等光学识别系统(未图示)识别连接器插芯100的端面,例如,如图5所示,可以识别出连接器插芯100的外轮廓1I所确定的中心CI,内孔1 2的中心C2、以及连接器插芯100的外圆直径。 [0069] As shown in FIG. 4, the connector ferrule 200 fixing device 100 fixed in advance, and then, the optical recognition system using a camera or the like (not shown) identifying the end face 100 of the connector ferrule, e.g., FIG. 5 , the center may be identified CI connector ferrule 100 is determined by the outer contour 1I, the central bore 12 of C2, and the outer diameter of the connector ferrule 100. 当然,也可以仅识别出连接器插芯100的外轮廓101所确定的中心Cl,或仅识别出连接器插芯100的外轮廓1I所确定的中心Cl以及内孔102的中心C2,或者仅识别出连接器插芯100的外轮廓101所确定的中心Cl以及连接器插芯100的外圆直径。 Of course, it is possible to identify only a central connector ferrule 100 Cl outer contour 101 determines or recognizes only a central connector ferrule 100 Cl outer contour 1I determined and the central bore 102 C2, or only identified connector ferrule outer diameter of the outer contour of 101,100 as determined by the center Cl of the ferrule 100 and the connector.

[0070 ]在识别出连接器插芯100的外轮廓所确定的中心CI,内孔1 2的中心C2、以及连接器插芯100的外圆直径之后,如果需要,可以松开固定装置200,并利用插芯位置调节系统(未图示)将插芯100的中心Cl调节到预定位置,例如,如图5所示,调节到插芯100的中心Cl与内孔102的中心C2处于同一条竖直直线上,并且使内孔102的中心C2位于插芯100的中心Cl的下方。 [0070] After identifying the center CI connector ferrule 100 of the outer contour of the determined center of the inner bore 12 of C2, and the outer diameter of the connector ferrule 100, if necessary, can release the securing means 200, position adjustment system using a ferrule (not shown) center of the ferrule 100 Cl is adjusted to a predetermined position, e.g., FIG. 5, the ferrule adjusted to the center of the center bore 100 and the Cl and C2 in the same 102 vertically on a straight line, and the center C2 of the hole 102 is positioned below the center Cl 100 of the ferrule.

[0071] 在插芯100的中心Cl调节到预定位置之后,可以再次利用固定装置200固定住插芯100,从而将插芯100的中心Cl保持在预定位置处。 After [0071] Cl in the center of the ferrule 100 is adjusted to a predetermined position, the fixing device 200 can be reused hold the ferrule 100, thereby the ferrule 100 is held in the center Cl at a predetermined position. 之后,如图6所示,可以将光纤300插入插芯100的内孔102中,例如,可以通过机械手或人工插入。 Thereafter, as shown in FIG. 6, the optical fiber 300 is inserted into the hole 102 of the ferrule 100, for example, can be inserted manually or by a robot.

[0072] 在光纤300插入插芯100的内孔102中之后,可以使用识别系统识别光纤300的包附层的中心C3、光纤300的纤芯的中心C4和光纤300的包附层的直径(或称为光纤300的直径)。 [0072] After the optical fiber 300 is inserted into the bore 100 of the ferrule 102 may be attached to the package layer diameter central bag attachment layer 300 of the optical recognition system C3, the central core of the optical fiber 300 and fiber 300 of C4 ( It referred to the diameter of the fiber or 300). 这样,就可以得到光纤300的包附层的中心C3、光纤300的纤芯的中心C4与插芯100的中心Cl和内孔102的中心C2之间的位置关系,如图7所示。 Thus, the package can be attached to the central layer of the optical fiber 300 C3, C4 positional relationship between the center of the optical fiber core 300 and the center Cl of the ferrule 100 and the central bore 102 C2, as shown in FIG. 当然,也可以仅识别出光纤300的纤芯的中心C4,或仅识别出光纤300的纤芯的中心C4以及光纤300的包附层的中心C3,或者仅识别出光纤300的纤芯的中心C4以及光纤300的包附层的直径。 Of course, it is recognized only the central core of the optical fiber 300 C4, C4, or recognizes only the central core of the optical fiber 300 and the central bag 300 is attached fiber layer C3, or recognizes only the central core of the optical fiber 300 C4 and the diameter of the optical fiber pack attachment layer 300.

[0073]由于光纤300的纤芯的中心C4与插芯100的中心Cl之间的偏差较大,如图7所示,因此,需要使用光纤位置调节系统400(如图8所示)调节光纤300的位置,使光纤300的纤芯的中心C4与插芯100的中心Cl对准,S卩,使光纤300的纤芯的中心C4与插芯100的中心Cl之间的差值在预定范围内,该预定范围可以为-0.3μηι至0.3μηι,优选地,该预定范围可以为-0.1ym至0.Ιμπι,更优选地,该预定范围可以为-Ο.ΟΙμηι至Ο.ΟΙμηι。 [0073] Due to the deviation between the center C4 of the optical fiber core 300 and the center Cl of the ferrule 100 is large, as shown in FIG. 7, therefore, require the use of optical fiber position adjustment system 400 (FIG. 8) adjusting optical fiber position 300, the central core of the optical fiber 300 C4 is aligned with the center Cl of the ferrule 100, S Jie, the central core of the optical fiber 300 C4 difference between the center of the ferrule 100 in a predetermined range Cl within the predetermined range may -0.3μηι to 0.3μηι, preferably, the predetermined range may -0.1ym to 0.Ιμπι, more preferably, the predetermined range may -Ο.ΟΙμηι to Ο.ΟΙμηι. 请注意,该预定范围可以由实际要达到的精度来确定。 Note that, the predetermined range may be determined by the actual accuracy to be achieved.

[0074] 如图7所示,要将光纤300的纤芯的中心C4移动到与插芯100的中心Cl对准,光纤位置调节系统400至少需要沿相互垂直的两个方向移动,例如,图示的水平方向和竖直方向。 [0074] 7, the central core of the optical fiber 300 To a C4 to move the ferrule 100 is aligned with the center Cl, fiber position adjustment system 400 to be moved at least in two mutually perpendicular directions, e.g., FIG. the horizontal and vertical directions is shown. 而且,如果需要,光纤位置调节系统400还需要对光纤300进行转动,以便调节光纤300的纤芯的中心C4相对于光纤300的包附层的中心C3的方位角,例如,使光纤300的纤芯的中心C4和光纤300的包附层的中心C3位于同一竖直直线上,并且使光纤300的纤芯的中心C4位于光纤300的包附层的中心C3的上方。 Further, if necessary, adjusting the position of the optical fiber system 400 also requires the optical fiber 300 is rotated to adjust the center C4 of the optical fiber core 300 with respect to the center of the optical fiber pack attachment layer 300 C3 azimuth, e.g., the optical fiber so that the fiber 300 C4 center of the central core and a cladding layer of the optical fiber 300 is attached to C3 located on the same vertical straight line, and the central core of the optical fiber 300 is located above the center of C4 package 300 attached to the fiber layer C3.

[0075]图9所示显示了调节后的光纤300的纤芯的中心C4、光纤300的包附层的中心C3、连接器插芯100的中心Cl和内孔102的中心C2的示意图。 [0075] FIG. 9 shows C4, central bag 300 is attached to the fiber layer C3, the center connector ferrule Cl 100 and C2 of the central bore 102 is a schematic diagram of the central core 300 of the optical fiber after the adjustment. 在调节之后,光纤300的纤芯的中心C4与连接器插芯100的中心Cl之间的距离小于或等于0.3μπι,从而实现了光纤300的纤芯的中心C4与连接器插芯100的中心Cl的对准。 After the adjustment, the optical fiber core 300 and the connector C4 center distance between the center of the ferrule 100 is less than or equal to CI 0.3μπι, thereby achieving the central core of the optical fiber connector and the center C4 of the ferrule 300 100 the alignment of Cl.

[0076] 在光纤300的纤芯的中心C4与连接器插芯100的中心Cl的对准之后,可以快速固化连接器插芯100顶部的固化剂,然后将连接器插芯100连同光纤300从固定装置200上释放取下,并放到固化箱做完全固化,从而通过固化剂将光纤300固定在插芯100的内孔102中,从而使光纤300的纤芯的中心C4与插芯100的中心Cl之间的相对位置保持不变。 [0076] After the optical fiber core 300 and the center of the C4 centering Cl connector ferrule 100 can be quickly cured connector ferrule 100 at the top of the curing agent, and 100 together with the optical fiber connector ferrule 300 from remove the securing means 200 is released, and fully into the curing oven for curing, the curing agent so that by the optical fiber 300 is fixed within the hole 102 in the ferrule 100, such that the central core of the optical fiber 300 and the ferrule 100 of C4 Cl relative position between the center remains unchanged.

[0077] 所述固化剂可以在光纤300插入插芯100的内孔102之前或之后灌注到插芯100的内孔102中。 The [0077] The curing agent may insert the ferrule 102 prior to or after filling the hole 100 of the ferrule 100 within the bore 102 of the optical fiber 300. 如果在光纤300插入插芯100的内孔102之前灌注到插芯100的内孔102中,则在光纤300插入插芯100的内孔102之后,还需要对光纤300的将被光纤位置调节系统400的夹具夹持的末端进行清洁处理。 If the ferrule insertion hole 100 in the optical fiber ferrule 300 is poured into the bore 102 until 102 100, the optical fiber 300 is inserted after the hole 102 of the ferrule 100, the optical fiber 300 needs to be adjusted the position of the optical fiber system a holder holding the end 400 of the cleaning process.

[0078] 前述固化剂可以通过毛细效应或真空吸附方式灌注到插芯100的内孔102中。 [0078] the curing agent may be poured into the bore 100 of the ferrule 102 by way of vacuum suction or capillary effect.

[0079]为了防止固化剂粘附到光纤位置调节系统400的夹具上,在本发明的一个实施例中,可以使光纤位置调节系统400的夹具的端面与插芯100的端面之间相隔0.5mm至1.0mm的间距。 Spaced 0.5mm between [0079] the curing agent to prevent adhesion of the fiber to the clamp position adjustment system 400, in one embodiment of the present invention, the optical fiber can clamp position adjustment system 400 and the end face of the ferrule end face 100 of the to the pitch of 1.0mm.

[0082]如图4所示,用固定装置200将连接器插芯100预先固定住,然后,利用摄像机等光学识别系统(未图示)识别连接器插芯100的端面,例如,如图5所示,可以识别出连接器插芯100的外轮廓1I所确定的中心Cl,内孔102的中心C2、以及连接器插芯100的外圆直径。 [0082] As shown in FIG. 4, the connector ferrule 200 fixing device 100 fixed in advance, and then, the optical recognition system using a camera or the like (not shown) identifying the end face 100 of the connector ferrule, e.g., FIG. 5 , the center may be identified Cl connector ferrule 100 is determined by the outer contour 1I, the central bore 102 C2, and the outer diameter of the connector ferrule 100.

[0083 ]在识别出连接器插芯100的外轮廓所确定的中心CI,内孔1 2的中心C2、以及连接器插芯100的外圆直径之后,松开固定装置200,并将插芯100夹持在对准工具的V-型槽500中,并转动插芯100,使插芯100的中心Cl、插芯100的内孔102的中心C2和V-型槽500的顶点位于同一条竖直直线L上。 [0083] After identifying the center CI connector ferrule 100 of the outer contour of the determined center of the inner bore 12 of C2, and the outer diameter of the connector ferrule 100, loosen the fixing device 200, and the ferrule 100 clamped in the alignment tool of the V- groove 500, rotation of the ferrule 100 and the ferrule 100 of the center CI, central bore 100 of the ferrule 102 and the V- and C2 apex slots 500 located on the same vertically on a straight line L.

[0084] 在插芯100的中心Cl、内孔102的中心C2调节到图10所示的位置之后,可以再次利用固定装置200固定住插芯100,从而将插芯100的中心Cl保持在图10所示的位置处。 After [0084] In the center of the ferrule 100 CI and C2 of the central bore 102 is adjusted to the position shown in Figure 10, again securing means 200 may utilize fixed ferrule 100, thereby the ferrule 100 is held in the center CI FIG. 10 in the position shown. 之后,如图6所示,可以将光纤300插入插芯100的内孔102中,例如,可以通过机械手或人工插入。 Thereafter, as shown in FIG. 6, the optical fiber 300 is inserted into the hole 102 of the ferrule 100, for example, can be inserted manually or by a robot.

[0085] 在光纤300插入插芯100的内孔102中之后,可以使用识别系统识别光纤300的包附层的中心C3、光纤300的纤芯的中心C4和光纤300的包附层的直径。 After [0085] inserted into the ferrule 102 in the bore 100 of the optical fiber 300, may be used recognition system central bag attachment layer 300 of the optical fiber C3, the diameter of the core layer attached to the package of fiber 300 and fiber 300 of the center C4.

[0086] 在识别出光纤300的包附层的中心C3、光纤300的纤芯的中心C4和光纤300的包附层的直径之后,如图11所示,可以光纤300夹持在对准工具的V-型槽500中,并转动光纤300,使光纤300的纤芯的中心C4、光纤300的包附层的中心C3和V-型槽500的顶点位于同一条竖直直线L上。 [0086] After identifying the central core of the fiber diameter of the central bag 300 is attached to C4 fiber layer 300 attached to C3 and the packet layer of the optical fiber 300, as shown in FIG. 11, the optical fiber can be clamped in the alignment tool 300 in the V- groove 500, and the optical fiber 300 is rotated, the central core of the optical fiber 300 C4, central bag 300 attached to the fiber layer C3 and the V- groove vertices 500 positioned on the same vertical straight line L. 这样,如图12所示,可以使得插芯100的中心Cl、插芯100的内孔102的中心C2、光纤300的纤芯的中心C4、光纤300的包附层的中心C3和V-型槽500的顶点位于同一条竖直直线L上。 Thus, 12 may be such that the ferrule 100 of the center CI, central bore 102 of the ferrule 100 C2, the central core of the optical fiber 300 C4, central bag attachment layer 300 of the optical fiber and the V- C3 apex slots 500 located on the same vertical straight line L.

[0087]如图12所示,由于光纤300的纤芯的中心C4与插芯100的中心Cl之间的偏差较大,因此,需要使用光纤位置调节系统400(如图8所示)调节光纤300的位置,使光纤300的纤芯的中心C4与插芯100的中心Cl对准,S卩,使光纤300的纤芯的中心C4与插芯100的中心Cl之间的差值在预定范围内,该预定范围可以为-0.3μηι至0.3μηι,优选地,该预定范围可以为-0.1μm至0.Ιμπι,更优选地,该预定范围可以为-Ο.ΟΙμηι至Ο.ΟΙμηι。 [0087] 12, since the deviation between the center C4 of the optical fiber core 300 and the center Cl of the ferrule 100 is large, therefore, it requires the use of optical fiber position adjustment system 400 (FIG. 8) adjusting optical fiber position 300, the central core of the optical fiber 300 C4 is aligned with the center Cl of the ferrule 100, S Jie, the central core of the optical fiber 300 C4 difference between the center of the ferrule 100 in a predetermined range Cl within the predetermined range may -0.3μηι to 0.3μηι, preferably, the predetermined range may -0.1μm to 0.Ιμπι, more preferably, the predetermined range may -Ο.ΟΙμηι to Ο.ΟΙμηι. 请注意,该预定范围可以由实际要达到的精度来确定。 Note that, the predetermined range may be determined by the actual accuracy to be achieved.

[0088] 如图12所示,要将光纤300的纤芯的中心C4移动到与插芯100的中心Cl对准,光纤位置调节系统400仅需沿竖直直线L的一个方向移动。 [0088] 12, the central core of the optical fiber 300 To a C4 to move the ferrule 100 is aligned with the center Cl, and L is an optical position adjustment in the vertical direction, the system 400 moves only linearly.

[0089]图13所示显示了调节后的光纤300的纤芯的中心C4、光纤300的包附层的中心C3、连接器插芯100的中心Cl和内孔102的中心C2的示意图。 [0089] FIG. 13 shows a C4, central bag 300 is attached to the fiber layer C3, the center connector ferrule Cl 100 and C2 of the central bore 102 is a schematic diagram of the central core 300 of the optical fiber after the adjustment. 在调节之后,光纤300的纤芯的中心C4与连接器插芯100的中心Cl之间的距离小于或等于0.3μπι,从而实现了光纤300的纤芯的中心C4与连接器插芯100的中心Cl的对准。 After the adjustment, the optical fiber core 300 and the connector C4 center distance between the center of the ferrule 100 is less than or equal to CI 0.3μπι, thereby achieving the central core of the optical fiber connector and the center C4 of the ferrule 300 100 the alignment of Cl.

[0090] 在光纤300的纤芯的中心C4与连接器插芯100的中心Cl的对准之后,可以使用固化剂将光纤300固定在插芯100的内孔102中,从而使光纤300的纤芯的中心C4与插芯100的中心Cl之间的相对位置保持不变。 [0090] After the optical fiber core 300 and the center of the C4 connector ferrule 100 centering Cl, a curing agent may be used in the optical fiber 300 is fixed within the hole 100 of the ferrule 102, such that the optical fibers 300 the relative position between the center core and the center Cl C4 ferrule 100 remains unchanged.

[0091] 所述固化剂可以在光纤300插入插芯100的内孔102之前或之后灌注到插芯100的内孔102中。 [0091] The curing agent may be inserted into the bore 100 of the ferrule before or after filling 102 into the bore 102 of the ferrule 100 in the optical fiber 300. 如果在光纤300插入插芯100的内孔102之前灌注到插芯100的内孔102中,则在光纤300插入插芯100的内孔102之后,还需要对光纤300的将被光纤位置调节系统400的夹具夹持的末端进行清洁处理。 If the ferrule insertion hole 100 in the optical fiber ferrule 300 is poured into the bore 102 until 102 100, the optical fiber 300 is inserted after the hole 102 of the ferrule 100, the optical fiber 300 needs to be adjusted the position of the optical fiber system a holder holding the end 400 of the cleaning process.

[0092] 如图10所示,在转动插芯100之后,所述插芯100的内孔102的中心C2位于所述插芯100的中心Cl的下方,并且,如图11所示,在转动光纤300之后,光纤300的纤芯的中心C4位于光纤300的包附层的中心C3的上方。 [0092] 10, after rotation of the ferrule 100, the ferrule 100 of the central bore 102 of ferrule C2 located below the center of the CI 100, and 11, the rotary after the optical fibers 300, 300 of the central core of the optical fiber is located above the center of C4 package 300 attached to the fiber layer C3. 这样,就能够减小光纤位置调节系统400沿竖直直线L移动的距尚,从而能够进一步提尚效率。 Thus, the optical fiber can be reduced in the vertical position adjustment system 400 moves away from the straight line L still, it is possible to still further improve the efficiency.

[0093]但是,本发明不局限于图10和图11所示的实施例,在转动插芯100之后,所述插芯100的内孔102的中心C2可以位于所述插芯100的中心Cl的上方,并且,在转动光纤300之后,光纤300的纤芯的中心C4可以位于光纤300的包附层的中心C3的下方。 [0093] However, the present invention is not limited to the embodiments shown in FIGS. 10 and 11, after rotation of the ferrule 100, the ferrule bore 100 of the center C2 102 may be located at the center of the ferrule 100 CI above, and, after the rotation of the optical fiber 300, the center C4 of the optical fiber core 300 may be positioned below the central bag 300 is attached to the fiber layer C3. 这样,同样能够减小光纤位置调节系统400沿竖直直线L移动的距离,从而能够进一步提高效率。 Thus, the same distance can be reduced fiber position adjustment system 400 moves along the vertical straight line L, thereby further improving efficiency.

[0094]为了防止固化剂粘附到光纤位置调节系统400的夹具上,在本发明的一个实施例中,可以使光纤位置调节系统400的夹具的端面与插芯100的端面之间相隔0.5mm至1.0mm的间距。 Spaced 0.5mm between [0094] the curing agent to prevent adhesion of the fiber to the clamp position adjustment system 400, in one embodiment of the present invention, the optical fiber can clamp position adjustment system 400 and the end face of the ferrule end face 100 of the to the pitch of 1.0mm.

[0095]在前述第一实施例和第二实施例中,所述插芯100的精度低于同类型的标准插芯的精度,例如,可以将插芯100的内孔102的直径增大到远大于同类型的标准插芯的内孔的直径,例如,可以将插芯100的内孔102的直径增大到大约130μπι,这样便于光纤300插入。 [0095] In the foregoing first embodiment and the second embodiment, the ferrule 100 is lower than the accuracy of the same type of standard precision ferrule, for example, the ferrule may be the diameter of the bore 100 is increased to 102 much larger than the standard diameter of the ferrule bore diameter of the same type, for example, the bore 100 of the ferrule 102 is increased to about 130μπι, it is easy to insert the optical fiber 300.

[0096]并且,在前述第一实施例和第二实施例中,所述光纤300的精度也低于同类型的标准光纤的精度。 [0096] Further, in the first embodiment and the second embodiment, the accuracy of the optical fiber 300 is lower than the accuracy of the optical fiber of the same type of standard.

[0097]利用本发明的前述方法,可以使低精度光纤的光纤模场中心(光纤纤芯的中心)与低精度的光纤连接器插芯的中心对准,从而消除连接器互配时由光纤模场中心的径向偏置所带来的插入损耗,即,本发明可以用低精度的插芯和低精度的光纤制造出高精度的光纤连接器。 [0097] With the foregoing method of the present invention, the optical fiber low accuracy mode field optical center (center of the fiber core) and low accuracy of the optical connector ferrule center alignment, when eliminating an optical fiber connector interworking radially offset mode field caused by the center of the insertion loss, i.e., the present invention can be manufactured with high precision optical fiber connector ferrule with an optical fiber and a low accuracy of the low accuracy.
