日本航空电子在千叶县幕张Messe举行的“InterOpto2000”上宣布,该公司正在开发利用MEMS(micro electro mechanicalsystems)技术的(2×2)×32光分歧/插入多重元件(OADM:optical add/drop multiplex-er).OADM元件是在对应DWDM通信系统中使用的元件,用于筛选出某个波长的信号或者追加信号.正在开发中的OADM元件,是通过组合32个2×2光开关元件实现的.每个光开关元件尺寸为16mm×20mm,消耗功率为10μW/元件,插入损失在1dB以下,串音(Cross Talk)为70dB以上.另外,光开关结构为在正方形台面(Stage)上配置反射镜形成的.使用静电调节该正方形台面上下运动,带动反射镜随之上下移动来改变激光光路.除此之外,该公司还展示了4×4光开关.光开关元件的尺寸为10mm×10mm.消耗功率为10μW/元件,插入损失最大6dB,串音(Cross Talk)确保在70dB以上.但是该公司表示不打算组装4×4以上的大规模产品.“对于大规模要求,打算以4×4元件做为1个单元,通过组合多个单元的方法来满足用户要求”.
JAL announced at “InterOpto2000” held at Messe, Chiba Prefecture that it is developing a (2 × 2) × 32 optical add / drop multiplexer using MEMS (micro electro mechanicalsystems) drop multiplexer. OADM element is used in the corresponding DWDM communication system for screening out the signal of a wavelength or additional signal OADM element under development, is a combination of 32 2 × 2 optical switching elements Each having a size of 16 mm × 20 mm, a power consumption of 10 μW / element, an insertion loss of 1 dB or less, and a cross talk of 70 dB or more. In addition, the optical switch structure is formed on a square stage In addition, the company also demonstrated the 4 × 4 optical switch. The size of the optical switching element is 10mm × 10mm. The power consumption is 10μW / element, insertion loss is 6dB, crosstalk is guaranteed to be over 70dB, but the company said it does not intend to assemble 4 × 4 or more large-scale products. “For large-scale requirements, 4 4 as a unit element, by the method of combining a plurality of units to meet user requirements. ”
