光阶分器及其网络的设计与应用

Design and application of ladder optical distributor and its network

光分路器的光路数目及其分光比,通常都是由网络设计者根据网络具体结构设计完成的,每个光分路器都需由生产厂家特制,大大增加了成本造价,而且在网络中的位置都是固定的,不能互换和替代,没有通用性。根据目前光接收机输入光功率动态范围都比较宽的特点,为便于光分路器的设计、生产、销售、使用、备份和维修,有必要将光分路器规范化、系列化,做成为数不多的几种型号和规格,供网络设计者选用。通过实例介绍了用几种实用的光阶分器设计和构建多元光阶分网络的原理与方法。

Optical path number and optical dividing ratio of optical distributor were customarily designed by designing of network according to the network configuration.Each optical distributor was specially made by factory,its cost was greatly increased,and the place of each optical distributor was fixed in network.In fact,the input power range was wide to the actual photoreceiver,Therefore,optical distributors were normally designed to be indispensable and beneficial to design,make,sale,use,backup or maintain.Ladder optical distributors and equal optical distributors were thereby presented.The method and principle to design and construct multiple ladder optical distributor network with the several practical ladder optical distributors were introduced through examples.
