Description

可插拔微型光无源器件 技术领域
本发明涉及一种用于光纤通信系统的光学器件，具体地说，是涉及一种可插拔微型光无源器件。
背景技术
随着光纤通讯技术的发展，波分复用技术作为一种在光域上的复用技术已经成为目前光层网络的主流技术。波分复用技术主要应用波分复用器件将光信号分成多束信号，因此，波分复用器件是实现波分复用技术的重要光学器件。
随着近年来大数据、云计算等高密度信息通讯技术的发展，波分复用器件也应用到数据中心的建设当中，因此，数据中心对小型化、微型化、即插即用的波分复用器件在机柜间扩展上有大量的需求。而目前光通讯行业的光无源器件或模块以分离器件或级联模块为主，一方面不方便与跳线直接连接，另一方面由于器件的尺寸都比较大，无法满足数据中心对器件小型化、微型化的需求。现在数据中心对波分复用等光无源器件的需求包括光无源器件的尺寸需要与常规的光学跳线基本一致或相同，只有满足这个条件下才能保证机箱面板上所有的跳线尾部露出长度相同，方便其布线。
为了解决上述问题，人们研发出一种如图1所示的可插拔的光纤跳线，该光纤跳线具有一个可插拔式微型波分复用器件10，用于将光信号分成两部分，分开的两部分光信号分别入射到可插拔式的光无源器件12、13中。
参见图2与图3，可插拔式的微型波分复用器10具有壳体15，壳体15包括连接器插头外壳16、跳线组件17、封装管18以及保护尾套19，陶瓷插芯21以及波分复用器24封装在壳体15内。陶瓷插芯21的大部分被连接器插头外壳16包套，且陶瓷插芯21的一端外伸到连接器插头外壳16外，另一端与止退件22邻接。在陶瓷插芯21与波分复用器24之间通过一根裸光纤23连接，裸光纤23连接到波分复用器24的一端。波分复用器24内需要设置光纤头，光纤头位于靠近裸光纤23的一端。波分复用器24的另一端连接有两根光纤25、26，光纤25、26从保护尾套19穿出。
然而，这种可插拔式的微型波分复用器10具有以下几个问题：首先，器 件的外形尺寸大，与行业标准跳线的长度尺寸相比长出50％，使用时会面临在机箱面板上跳线头外露长度高低不一致问题。由于这种器件露出过长的尾部容易被碰到造成损坏,同时由于力臂变长承受侧拉能力下降。
其次，由于这种器件相对于行业标准跳线的尺寸变长，这种器件插到面板上后尾部光缆由于重力的作用会产生侧拉的力，由于器件增长，侧拉的力臂变长，器件很难符合IEC规范中对光缆跳线侧拉的要求，产品寿命较短。
再次，将这种器件的陶瓷插芯21固定时，由于结构上的因素取消了用于缓冲的自适应弹簧结构，会造成插拔过程中只剩下与可插拔式微型波分复用器10相匹配的另外一侧的器件内的弹簧缓冲，缓冲效果变差，导致插拔器件冲击力过大且易损伤，同时也不符合IEC的规范。
此外，该器件内部的波分复用器24与陶瓷插芯21间的连接采用了脆弱的125微米的裸光纤23实现，裸光纤23在加到前端陶瓷插芯21上时需要预先制作一个独立的光无源器件，然后在器件的单线透射端进行剥纤并穿入陶瓷插芯21的操作，由于上述操作复杂而且玻璃光纤在剥纤过程中极易断裂，影响产品的合格率。同时，成品器件在冲击震动过程中也会发生轻微的位移导致裸光纤23受损断裂。
最后，由于这种可插拔式微型波分复用器10使用较多的金属管或塑料管，增加了器件的制造成本。
发明内容
本发明的主要目的是提供一种尺寸小且能够行业标准跳线的长度尺寸相匹配的可插拔微型光无源器件。
本发明的另一目的是提供一种不易损坏且生产成本较低的可插拔微型光无源器件。
为了实现上述的主要目的，本发明提供的一种可插拔微型光无源器件，包括一个壳体，壳体内安装有一光学器件，光学器件的第一端设有一第一陶瓷插芯，第一陶瓷插芯内设有至少一纤芯，第一陶瓷插芯的第一端伸出壳体外，第一陶瓷插芯的第二端位于光学器件内，且第一陶瓷插芯的第二端镀有一增透膜，第一陶瓷插芯的第二端贴近地设有一透镜，透镜位于光学器件内；光学器件内还设有至少一根光纤，光纤的第一端设置在靠近透镜且远离所述第一陶瓷插芯的一侧，光束经陶瓷插芯、透镜入射到光学器件的光纤。
由上述方案可见，本发明的可插拔微型光无源器件将陶瓷插芯以及透镜封装在同一光学器件内，并且在陶瓷插芯的第二端设有增透膜，再将陶瓷插芯的第二端与透镜贴近地设置在一起，从而不需要在陶瓷插芯与光学器件之间设置裸光纤，使可插拔微型光无源器件的尺寸可以做得很小，能够与行业标准跳线的长度尺寸相匹配，并且去除了裸光纤之后也不需要使用较多的金属管或者塑料管，制造成本较低。
此外，由于可插拔微型光无源器件内没有设置裸光纤，在插拔的过程中不会发生裸光纤断裂的情况，确保产品的合格率，也确保产品的使用寿命。
一个优选的方案是，光学器件在靠近第一端的位置处设有一第一止退件，且止退件的中部设有一通孔，第一陶瓷插芯插入到通孔内。并且，壳体内设有一弹簧，弹簧的第一端抵接在止退件的端面上，壳体内的周壁上设有一肩台部，弹簧的第二端抵接在肩台部上。
由此可见，可插拔微型光无源器件在插拔过程中通过弹簧来缓冲光学器件的冲击力，避免光学器件因受到过大的冲击力而容易损坏，从而延长可插拔微型光无源器件的使用寿命。
进一步的方案是，壳体的第二端设有一第二陶瓷插芯，第二陶瓷插芯位于光学器件的第二端，且光学器件的第二端设有一第二止退件。
可见，在壳体内设置两个陶瓷插芯从而形成双头器件，使可插拔微型光无源器件可以直接连接到两个不同的光学设备上，满足不同光学设备的连接需求。
更进一步的方案是，壳体包括包套在第一陶瓷插芯外的一第一连接器插头外壳、包套在光学器件外的一转接组件以及包套在第二陶瓷插芯外的一第二连接器插头外壳。
由此可见，使用两个不同的连接器插头外壳分别包套两个陶瓷插芯，可插拔微型光无源器件两端的外壳结构相同，方便可插拔微型光无源器件实现两端正反方向的连接。
可选的方案是，壳体包括包套在第一陶瓷插芯外的一第一连接器插头外壳、包套在光学器件中间区域的外部的一转接组件以及包套在光学器件的第二端外的一封装帽，第二陶瓷插芯的端部伸出封装帽并包套在一法兰内。
可见，在可插拔微型光无源器件的一端设置法兰，可以满足特殊场合下可插拔微型光无源器件的安装需求，使可插拔微型无源器件的使用场合更加 广泛。
更进一步的方案是，陶瓷插芯内具有一根以上的纤芯。在陶瓷插芯内的纤芯为两根或三根时可以形成2×4、3×3等多种不同规格的波分复用器件，产品的结构更加灵活。

具体实施方式
本发明的可插拔微型光无源器件用在光纤系统中，可以是波分复用器件、光隔离器、光环形器、光分束器等不同的光学器件。
第一实施例：
参见图4，本实施例的可插拔微型光无源器件可以作为波分复用器件，其具有壳体30，壳体30包括连接器插座外壳31、跳线组件32以及保护尾套33，连接器插座外壳31的中部设有通孔34，通孔34贯穿连接器插座外壳31的两端，并且连接器插座外壳31上设有弹性件35。跳线组件32的一部分插入到连接器插座外壳31内，从而实现跳线组件32与连接器插座外壳31的固定连接。跳线组件32的外壁上设有止挡件36，弹性件35的端部抵接在止挡 件36的下方。保护尾套33位于跳线组件32远离连接器插座外壳31的一侧，且保护尾套33与跳线组件32固定连接在一起。
参见图5与图6，在壳体30内装有陶瓷插芯43以及作为光学器件的波分复用器40、弹簧47，陶瓷插芯43的内部设有一纤芯432，陶瓷插芯43的第一端41(或是说前端)向前伸出壳体30外，且陶瓷插芯43的大部分位于连接器插座外壳31的通孔34内。如图7与图8所示，陶瓷插芯43的第二端42插入到波分复用器40的第一端，在波分复用器40的第一端还设有一透镜45，陶瓷插芯43的第二端42贴近地设置在透镜45的端面前方,其中在陶瓷插芯43的第二端42与透镜45之间设有一间隙422，该间隙422的大小可以根据光学性能的需求进行调整，一般是介于0.15毫米至0.2毫米之间。优选地，陶瓷插芯43的第二端42上镀上一增透膜，特别是在纤芯432的第二端镀上增透膜，提高纤芯432的透光性从而可以减少光束的损耗，并且透镜45靠近陶瓷插芯43的端面44为斜面，也就是透镜45靠近陶瓷插芯43的端面44与陶瓷插芯43第二端42的端面呈倾斜设置，从而可以阻止透镜45的端面44的反射光反向返回纤芯432。透镜45可以作为光纤准直器，用于将光束准直并让光束入射到波分复用器40的光纤内。
波分复用器40内设有一光纤，光纤的一端靠近透镜45的端面，光束可以经陶瓷插芯43、透镜45入射到波分复用器40的光纤内。并且，透镜45远离陶瓷插芯43的端面上可以镀上波分复用膜。当然，如果光学器件40不是波分复用器，则无需在透镜45上镀上波分复用膜。
在波分复用器40的第一端外侧设有止退件48，波分复用器40安装到壳体40后，止退件48被包套在连接器插座外壳31内。从图8可见，止退件48的中部设有通孔，陶瓷插芯43的第二端42穿过该通孔内。并且，跳线组件32的内壁上设有肩台部46，弹簧47套在波分复用器40的第一端的外周，且弹簧47的两端分别抵接在止退件48的端面以及肩台部46上。波分复用器40的第二端连接有一光纤49，光纤49被包套在保护尾套33内，并且光纤49被分开成两根光纤51、52并从保护尾套33伸出。
参见图6，从陶瓷插芯43的横截面可见，陶瓷插芯43内设有一根纤芯432，因此光束从陶瓷插芯43入射后被波分复用器40分成两束光束并分别从光纤51、52出射，实现光束的分束。
本实施例中，陶瓷插芯43的第二端42、止退件48包套在连接器插座外 壳31内，波分复用器40的大部分包套在跳线组件32内，弹簧47包套在连接器插座外壳31及跳线组件32内，而波分复用器49的第二端、光纤49包套在保护尾套33内。
制造波分复用器40时，需要在陶瓷插芯43的第二端42上镀上增透膜，并且在波分复用器40内安装了透镜45的情况下将陶瓷插芯43插入到波分复用器40内。待可插拔微型光无源器件封装后，对陶瓷插芯43的第一端41进行研磨，得到最终的成品。
由于可插拔微型光无源器件使用陶瓷插芯43作为跳线插芯以及波分复用器40的光纤头的共用件，这样无需在可插拔微型光无源器件内使用裸光纤来连接跳线插芯以及波分复用器40，可插拔微型光无源器件的长度较小，能够与行业标准跳线的长度尺寸相匹配，满足行业对可插拔微型光无源器件体积小型化、微型化的需求。并且，由于可插拔微型光无源器件不设置裸光纤，器件的制造工艺简单，且不会因裸光纤断裂而造成器件的使用寿命较短等问题。此外，由于器件的尺寸较小，制造壳体30所有的材料较少，可以降低器件的生产成本和制作难度。
与此同时，可插拔微型光无源器件内设置止退件48以及弹簧49，在器件插拔过程中可以有效缓冲冲击力对波分复用器等光学器件的损伤，同时，避免光纤对准过程中的横向适配，可以延长器件的使用寿命。
第二实施例：
参见图9，本实施例的可插拔微型光无源器件可以是实现光隔离等功能的器件，其具有壳体60，本实施例的壳体60包括依次连接的连接器插座外壳61、跳线组件62以及保护尾套63，壳体60内装有陶瓷插芯65以及光学器件64，陶瓷插芯65的第一端伸出连接器插座外壳61，第二端位于光学器件64内，并且在第二端的端面上镀有增透膜。光学器件64内设有透镜，透镜位于陶瓷插芯65第二端的一侧。
在光学器件64的第一端设有止退件66，且光学器件64的第一端外套装有弹簧67，跳线组件62内壁上设有肩台部68，弹簧67的两端分别抵接在止退件66的端面上以及肩台部68上。这样，可插拔微型光无源器件插拔的时候弹簧67可以为器件缓冲冲击力，避免光学器件64的损伤。
与第一实施例不同的是，本实施例的保护尾套63内仅包套有一根光纤69，也就是光束经过光学器件后直接从一个光纤69出射，因此光学器件64 可以为光衰减器，光隔离器等光学器件。
第三实施例：
参见图10，本实施例可插拔微型光无源器件可以是实现波分复用功能的器件，其具有壳体70，壳体70包括依次连接的连接器插座外壳71、跳线组件72以及保护尾套73，壳体70内装有陶瓷插芯75以及波分复用器74，陶瓷插芯75的第一端伸出连接器插座外壳71外，第二端位于波分复用器74内，并且第二端的端面上镀有增透膜。波分复用器74内设有作为光纤准直器的透镜，透镜位于陶瓷插芯75第二端的一侧。
在波分复用器74的第一端设有止退件76，且光学器件74的第一端外套装有弹簧77，跳线组件72内壁上设有肩台部，弹簧77的第一端抵接在止退件76的端面上，第二端抵接在肩台部上。
本实施例的保护尾套73内包套有三根光纤78，且陶瓷插芯75内设有三根纤芯，因此本实施例的可插拔微型光无源器件为3×3的光隔离器件或光衰减器件。
第四实施例：
参见图11，本实施例可插拔微型光无源器件可以也是实现波分复用功能的器件，其具有壳体80，壳体80包括依次连接的连接器插座外壳81、跳线组件82以及保护尾套83，壳体80内装有陶瓷插芯85以及波分复用器84，陶瓷插芯85的第一端伸出连接器插座外壳81外，第二端位于波分复用器84内，并且第二端的端面上镀有增透膜。波分复用器84内设有透镜，透镜位于陶瓷插芯85第二端的一侧。
在波分复用器84的第一端设有止退件86，且光学器件84的第一端外套装有弹簧87，跳线组件82内壁上设有肩台部，弹簧87的第一端抵接在止退件86的端面上，第二端抵接在肩台部上。
本实施例的保护尾套83内包套有四根光纤88，且陶瓷插芯85内设有两根纤芯，因此本实施例的可插拔微型光无源器件为2×4的波分复用器件。
第五实施例：
参见图12，本实施例具有壳体90，壳体90包括依次连接的连接器插座外壳91、转接组件92以及连接器插座外壳93，其中连接器插座外壳91上设有弹性件94，连接器插座外壳93上设有另一个弹性件95。
壳体90内装有光学器件96，光学器件96的第一端设有陶瓷插芯97，第 二端设有另一根陶瓷插芯101，陶瓷插芯97的第一端伸出连接器插座外壳91外，第二端位于光学器件96内，且光学器件96内设有用作光路连通的光纤及作为光纤准直器的透镜，该透镜位于陶瓷插芯97的第二端的一侧。光学器件96的第一端设有止退件98，且光学器件96的第一端外套装有弹簧99，且转接组件92的内壁设有肩台部100，弹簧99的第一端抵接在止退件98的端面上，第二端抵接在肩台部100上。
陶瓷插芯101的第一端伸出连接器插座外壳93，第二端位于光学器件96内，且光学器件96位于陶瓷插芯101第二端的一侧设有另一个透镜，在光学器件96的第二端设有止退件102。
本实施例中，光学器件96的第一端、陶瓷插芯97的大部分以及止退件98包套在连接器插座外壳91内，光学器件96的中部包套在转接组件92内，而光学器件96的第二端、陶瓷插芯101的大部分以及止退件102包套在连接器插座外壳93内。这种封装的可插拔微型光无源器件可以满足特殊场合的使用需求。
第六实施例：
