摘要： An optical fiber ferrule assembly equipped with an angular index (2) for indicating a polarization plane of an optical fiber (4). The assembly comprises a polarization plane maintaining optical fiber (4), an optical fiber ferrule (1) for accommodating the optical fiber so that the optical fiber is fixed thereto in a state that a tip end surface of the optical fiber is exposed, and an angular index member (2). The angular index member is rotatable with respect to the ferrule (1) and fixed at a constant angle with respect to a polarization plane of said optical fiber (4). The angular index member (2) and the optical fiber ferrule (1) temporarily assembled, to which the optical fiber (4) is fixed, are connected with each other and one of them is fixed, and a tip end surface of the optical fiber is enlarged for observation to decide the polarization plane thereof on the basis of its configuration, and they are relatively rotated and fixed to each other so that the angular index makes a constant angle relative to the polarization plane.

摘要： Traversée (2) pour fibre optique dans laquelle une fibre (6) de maintien de polarisation (PM) est scellée dans une gaine métallique (14) au moyen d'un scellement (20) en verre. Le scellement (20) applique des contraintes asymétriques à la fibre (6) orientée de façon que ces contraintes renforcent ses propriétés de maintien de polarisation. Ce dispositif réduit les tolérances de fabrication nécessaires pour éviter de détruire les propriétés de maintien de polarisation d'une fibre associée à des scellements produisant une contrainte symétrique. Il s'applique aux boîtiers de composants opto-électroniques. L'invention se rapporte également à une double traversée pour fibre optique.

摘要： A fiber optic connector assembly (10) includes an outer connector housing (12) defining an optic axis (16) in a through passage (14). A first key (50) is disposed in the passage at a given position angularly about the axis. An inner optical fiber plug (34) terminates an optical fiber and is disposed in the passage and includes a second key (42, 48) movably positionable about the periphery of the plug to different selected positions of rotational adjustment for the plug. The second key is fixable at any selected position on the plug and is lockable with the first key on the housing to fix the angular position of the plug relative to the housing and, thereby, fix the rotational position of the optical fiber angularly of the optic axis.

摘要： The present invention aims at providing a connecting method of optical devices capable of suppressing a periodic wavelength dependence loss and the like, due to the inter-polarization-mode interference caused when connecting a plurality of optical devices by using an optical path having a polarization-preserving characteristic, and an optical apparatus applied with the connecting method. To this end, the connecting method according to the present invention, is to connect a plurality of optical devices (11,12) to one another by using an optical path (212) of polarization-preserving type having optical characteristics in which a light is propagated along two different polarization axes for substantially equal distances. Thus, even if the polarization direction of the light input/output to/from the respective optical devices is not completely coincident with the direction of the polarization axis of the optical path, it is possible to offset the periodic wavelength dependence loss and the like caused by the inter-polarization-mode interference in the optical path, to be suppressed.
摘要翻译：本发明的目的在于提供一种能够抑制周期性波长相关损耗等的光学器件的连接方法，这是由于通过使用具有偏振光的光路连接多个光学器件时引起的偏振模式间干扰，保存特性，以及应用了连接方法的光学装置。为此，根据本发明的连接方法是通过使用具有光学特性的偏振保持型光路（212）将多个光学器件（11,12）彼此连接，其中光是沿两个不同的偏振轴传播大致相等的距离。因此，即使向各光学装置输入/输出的光的偏振方向与光路的偏振轴的方向不完全一致，也可以抵消周期性波长相关损耗等通过光路中的偏振模干涉被抑制。
