Your equipment’s documentation or its supplier should be able provide the answer.Balanced outputs come in different flavours; On the one hand there are the true balanced transformer outputs which are completely galvanically isolated and therefore are the least problematic. On the other hand there are the so-called “transformerless” - also named “electronically balanced” - outputs which nowadays are common on most professional equipment. These transformerless/electronically balanced outputs come in two types:1. Quite commonly seen is the plain “pseudo balanced” phase/antiphase output, where the equipment’sinternal unbalanced signal is simply fed to signal + out (XLR pin 2) by means of an opamp buffer and isfed to signal – out (XLR pin 3) simply by means of a polarity inverting opamp. This doesn’t implement atrue balanced output and rather can be looked upon as a pair of unbalanced outputs, one being polarityinverted. Here the above Fig. 1’s wiring configuration is recommended.2. Much more sophisticated is the so-called “cross coupled output stage” in which two cross coupled opampsmimic an output transformer. Here the above Fig. 2’s wiring configuration is recommended.Regarding Fig. 2 and Fig. 3:In case of RF interference, connecting the cable shield to signal ground at the unbalanced signal receiving side’s connector through a 10 nanoFarad ceramic disc capacitor will often solve the problem.Note: Mixed interconnection of electronically balanced and unbalanced equipment remains prone to hum and noise problems since these two types of signal operation are incompatible.

(b ) PC 面球心飘移小于30μm ,回损大于40dB ;APC 面回损大于50dB 。

(c ) PC 面插入损耗小于0.2dB ;四个方向插入损耗最大差值不超过0.1dB ; (d ) 陶瓷端面区域的划分:(e )PC 面洁净度要求如下检验区域合格标准放大倍数区域 端面范围具体尺寸划痕不可除的脏污可擦除脏污 1光纤中心+光纤包层1φ20μm 内不能有不能有不能有2002光纤包层2φ20μm ~φ125μm宽度10μm 以内,≤4条直径10~30μm ,≤4个 直径≤10μm ,允许不能有2003 灌胶层 φ125μm 光纤破损<10μm ,陶瓷破损<10μm ,间隙<5μm 2004接触层φ125μm ~φ260μm宽度10μm 以内,≤4条 直径10~30μm ,≤4个 直径≤10μm ,允许 不能有2005陶瓷端面φ260μm ~φ2.0mm允许直径30μm 以内,允许; 直径30~50μm ,≤3个 不能有2006倒角区φ2.0mm ~φ2.5mm允许允许不能有 200检验区域合格标准放大倍数区域端面范围具体尺寸划痕不可除的脏污可擦除脏污1 光纤中心φ9μm内不能有不能有不能有1002 光纤包层φ9μm~φ125μm宽度5μm以内,≤6条直径10μm以内,小于8个直径≤10μm,允许不能有1003 灌胶层φ125μm 光纤破损<10μm,陶瓷破损<10μm,间隙<5μm 1004 陶瓷端面φ260μm~φ1.6mm允许允许不能有501.球心偏移(Apex Offset)定义为陶瓷插针凸球面球心与陶瓷插针圆柱体轴心之间的距离,偏心通常被控制在50um以内,偏心过大不仅会对连接器的光学特性产生不良影响,还会增加系统的误码概率。

2..纤芯高度(Under Cut/Protrusion):是指光纤端面与陶瓷插针端面的距离,通常被控制在±0.05um以内,如果光纤端面突出于陶瓷插针表面过多,当两个连接器对接时会造成光纤表面的刮伤,如果光纤表面内缩于陶瓷插针表面太多,则会造成两个连接器对接时的非物理性接触,连接器之间会有空气间隙,由于光信号在陶瓷插针与空气的接触面上发生非涅尔反向,导致后向反射光的增加,对系统的光源造成干扰,增加了系统的不稳定性。

3..曲率半径(Rsdius Of Curvature):指陶瓷插针凸球面的半径,曲率半每项过大会使球面过于平坦,低了光纤的对准精度,使光学特插针休1 -402-001710.pdf试,需要高精度的光学干涉仪,在选购陶瓷插芯类的物料时,最好是让厂商提供测试数据或实际的端面干涉图样。

(b) 首次送样附材质分析报告并通过正源光子焊接试验(c) 更换批次或更换供应商须通知正源光子,并且重新送样进行焊接试验(附材质分析报告)。

(d) 装配之前必须按照正源光子的要求进行清洗并检验。

5.8外观尺寸要求3.结构件相互间配合的要求3.1 FIBER STUB 与Bottom相互配合的标准引用标准(IEC 61754-4):当不互配时,尺寸H是相对插头端面给出的,插针是通过中心轴向压力随接触端面方向而移动的,因此,尺寸H是可变的。

当尺寸H是7mm+0.1mm时,插针压力应为7.8N~11.8N。

FIBER STUB到SC House端面的距离6.1~6.84mm,FIBER STUB 与Bottom之间配合力应13.8N~38.7N,将极限值考虑在内,陶瓷插芯与金属座的配合在工工业温度下50N不能产生位移。

3.2Assembly 与 House 之间的配合要求Assembly 与 House 之间采取紧配合的方式,配合要求配合力:100N垂直度:0.03mm1.FERRULE与SLEEVE的配合要求保证FERRULE放入SLEEVE的长度与连接器放入跳线的上度一致,保证插拨的重复性与互换性。

插拨力要求引用标准(IEC 61754-4):连接器对中装置是一个弹性套筒,该装置应充许:在一根量规针从适配器一侧完全插入的条件下,另一根规针从另一侧插到适配器的中部时的压力应为2.0N~5.9N,适配器中部尺寸H由右边位置定义.4结构件设计要求4.1FIBER STUB尺寸设计要求1)焊接面须与to封焊管体尺寸一致辞.2) PC端陶瓷受到标准连接器的推力,要保证陶瓷不会发生位移.3) BOTTOM与HOUSE配合面尺寸为紧配合,配合尺寸在0.005~0.15mm左右4) 陶瓷与HOUSE配合后,PC端面到HOUSE的距离要求为6.1~6.8mm之间4.2HOUSE尺寸设计要求1)与标准连接器适配端的尺寸设计需要根据连接器的尺寸来设计,内径在 2.6~2.8mm之间,外径要求在式4..7~4.8mm之间,2)HOUSE与SLEEVE装配部份要防止两零件之间的相互干涉,标准连接器与RECEPTACLE对接时,套筒首先会有个倾斜的过程,经计算,套筒与金属件的间隙大于0.18MM连接器对中装置是一个弹性(开口)对中套,该装置在一根量规针从其一端插到适配器中心位的条件下,另一量规针从另一端插至与已插针规相碰结时,必须且有1.0N~2.5N的力,量规针标称直径是1.2490适配器中心部位由尺寸B左边位置定义。
