用于FOCCoS-PFS-Subaru的多光纤连接器系统
Multi-fibers connectors systems for FOCCoS-PFS-Subaru
摘要：
光纤电缆和连接器系统（FOCCoS）通过光纤电缆在2400个定位器和一组光谱仪之间提供光学连接，作为斯巴鲁望远镜PFS仪器的一部分。光纤电缆将沿路线分为3部分，电缆A、电缆B和电缆C，通过一组多光纤连接器连接。USCONEC公司生产研究中的多光纤连接器。USCONEC 32 F型号可以连接32根光纤，采用4 x 8矩阵排列。套圈由耐用的复合材料聚苯硫醚（PPS）基热塑性塑料制成。连接通过一个推/拉闩锁固定到位，连接器也可以通过从连接器前部突出的一对金属导销来区分。每个连接器将使用两根光纤监测连接程序。它被发现很容易抛光，而且它足够小，可以成组安装。像PFS这样的高度多路复用的仪器需要一个光纤连接器系统，可以提供出色的光学性能和可靠性。PFS需要两种不同类型的结构来组织连接器。塔连接器系统包括80个多光纤连接器，是一组连接器，用于连接电缆B（望远镜结构）和电缆C（定位器板）。Gang连接器系统是一组8个Gang连接器，每个连接器有12个多光纤连接器，用于连接电缆B（望远镜结构）和电缆A（光谱仪）。这些连接器系统和所选光纤的台架测试应测量光的吞吐量以及多次连接和断开后的稳定性。在本文中，我们描述了测试和程序来评估吞吐量和FRD增量。套圈的寿命也在评估中。
英文摘要：
The Fiber Optical Cable and Connector System (FOCCoS), provides optical connection between 2400 positioners and a set of spectrographs through optical fibers cables as part of PFS instrument for Subaru telescope. The optical fiber cable will be segmented in 3 parts along the route, cable A, cable B and cable C, connected by a set of multi-fiber connectors. The company USCONEC produces the multi-fiber connector under study. The USCONEC 32F model can connect 32 optical fibers in a 4 x 8 matrix arrangement. The ferrules are made of a durable composite, Polyphenylene Sulfide (PPS) based thermoplastic. The connections are held in place by a push-on/pull-off latch, and the connector can also be distinguished by a pair of metal guide pins that protrude from the front of the connector. Two fibers per connector will be used for monitoring the connection procedure. It was found to be easy to polish and it is small enough to be mounted in groups. Highly multiplexed instruments like PFS require a fiber connector system that can deliver excellent optical performance and reliability. PFS requires two different types of structures to organize the connectors. The Tower Connector system, with 80 multi-fiber connectors, will be a group of connectors for connecting cable B (Telescope Structure) with cable C (Positioners Plate). The Gang Connector system is a group of 8 gang connectors, each one with 12 multi-fibers connectors, for connecting cable B (Telescope Structure) with cable A (Spectrograph). The bench tests with these connector systems and the chosen fibers should measure the throughput of light and the stability after many connections and disconnections. In this paper we describe tests and procedures to evaluate the throughput and FRD increment. The lifetime of the ferrules is also in evaluation.
