美国康宁公司的Payout单模光纤在弯曲直径小达4.8mm时仍可获得低衰减,这种光纤主要为各种军事和传感器应用所设计,据说它的模场直径比大多数标准电信光纤小。该光纤可用于光纤制导的导弹,快速部署战术光缆和光纤缠绕成线圈的传感器(诸如干涉传感器)中。它采用CPC5(一种耐磨的丙烯酸酯)涂覆。该公司采用匹配包层单模结构,以改善小弯曲直径时的性能。由于该光纤芯径较小并且芯径区是高掺杂的,所以它的截止波长接近1250nm,从而使它能够在1300nm和1550hm波长工作,模场直径在1550am波长时为6.5μm,在1300nm时为5.5μm。
Payout single mode fibers from Corning Incorporated in the United States still achieve low attenuation at bend diameters as small as 4.8 mm. The fibers are designed primarily for a variety of military and sensor applications and are said to have mode field diameters that are smaller than most standard telecommunications fibers. The fiber can be used in fiber-guided missiles, rapid deployment of tactical fiber optic cables and sensors in optical fiber wound into coils, such as interferometric sensors. It is coated with CPC5 (a wear-resistant acrylate). The company uses a matched single-mode cladding structure to improve performance at small bend diameters. Due to its small core diameter and high doped core area, it has a cut-off wavelength close to 1250 nm, enabling it to operate at 1300 nm and 1550 hm with a mode field diameter of 6.5 μm at 1550 nm and 1300 nm Is 5.5 μm.
