磨损

Excessive grinding or abrasion of this product may create airbome dust and fober concentrations in excess of state and Federal OSHA permissible exposure limits.if employee exposures exceed these PELs,local exhanst ventilation or other mechanical ventilation systems may be required to reduce such exposures to concentrations below the PELs.if mechanical exhaust ventilation is necessary,exhaust air should be appropriately filtered or otherwise controlled to meet local ,state and Federal air pollution and air quality laws and standards

磨削过度磨损或这种产品可能造成机载尘fober浓度超过州政府和联邦政府1921年允许暴露限定。如果雇员暴露超过这些研究生，局部排气通风或其他机械通风系统，可要求减少这种暴露浓度低于该PELs。如果机械排风是必要的，排风应适当过滤或以其他方式控制，以符合当地，州和联邦空气污染和空气质量法规和标准

Then the MEMS solenoid type electromagnetic actuating and novel, frictionless and wear-free, and simple structure are designed for fiber-deflecting type MEMS VOA: One of the two coupled single mode fibers is completely fastened in one of the three aligned U-shaped grooves while the deflectable fiber is partially fixed in another groove with a long front section suspending over the wider groove as a cantilever beam. The two fibers, any one for input and the other for output, are well aligned initially so that the insertion loss is very low. Beside the deflectable fiber is a solenoid microactuator with a U-shaped permalloy core attracting a permalloy piece glued on side of the fiber cantilever so that the fiber is deflected and the optical power coupled between the fibers decreased continuously. Using MEMS solenoid as a continuous actuator and the novel structure of VOA are not seen in literature.

为光纤偏移型MEMS可变光衰减器设计了MEMS螺线管电磁驱动方式以及新颖的避免了静摩擦、磨损而且简单的整体结构形式：在硅基片的三段V形槽结构中，将两个对接单模光纤之一完全固定在基片上，只将另一根光纤的稍后部位固定于基片上而使其前端的一定长度悬空，形成一个悬臂梁结构；初始对准后两根光纤之间的光传输损耗很小；通过U型铁芯MEMS螺线管吸引固定于光纤悬臂梁上的坡莫合金片，驱动光纤悬臂梁连续偏移以使两根光纤之间功率传输系数连续变化，从而达到光功率连续衰减的目的。
