加拿大“拉姆”公司(经销部:Microscan GmbH)将用于光纤技木上的用两个盒装的定向耦合器和星形耦合器投放到了欧洲市场。1000系列的定向耦合器所具有的耦合比在1:1和99:1之间。通常使用各种光纤,其中突变型光纤采用 10/140μm,渐变型光纤采用 50/126μm。所有耦合器都给所选用的各种光纤提供45cm比特率。2000系列的对称式星形耦合器总会有3和8之间的输出输入通道。根据顾客的要求还可以生产多于16个支路的样品。此耦合器盒的最大损耗如果是2dB时,所具有的定向作用大于 40dB。当然,普通的光纤盒也适用。
Canada “Ram” company (Distribution: Microscan GmbH) will be used for optical technology wood with two boxed directional couplers and star couplers into the European market. The 1000 series directional couplers have a coupling ratio between 1: 1 and 99: 1. A variety of fibers are commonly used, with mutant fibers using 10/140 μm and tapered fibers using 50/126 μm. All couplers provide a 45cm bit rate for the various fibers selected. The 2000 series symmetrical star coupler always has an output input channel between 3 and 8. Depending on the customer’s requirements, samples of more than 16 branches can also be produced. With a maximum loss of 2 dB, the coupler box has an orientation greater than 40 dB. Of course, ordinary fiber optic boxes are also suitable.
