OFS has the ability to package your 光纤-based solution with various coating tailored to your critical application requirements. Here are some of the options that can be discussed further with our coatings technologists.
什么是光纤涂层/缓冲器?
Optical fiber coatings/buffers play an important role in protecting the fiber from its intended environment. The coating protects the glass fiber from mechanical 和 environmental stresses in application. 主涂层可以单层或双层涂敷. Coatings are applied during the fiber draw process 和 before touching any external surface. 为 额外的保护时,可加一层缓冲材料. The buffer material provides additional mechanical protection for the fiber 和 helps preserve the waveguide.
什么是光缆护套?
光纤结构可以保护光纤免受环境损坏. 缆索结构包括缓冲器、强度构件和护套. 影响设计的因素很多 光纤电缆. 电缆设计涉及电缆的预期应用.

光缆层数
光纤涂层:
丙烯酸酯纤维涂层
Photocurable liquid coating compositions adapted to provide primary coatings for optical glass fibers. St和ard telecoms 光纤s use a dual coating of acrylate (a softer inner coating 和 a harder outer layer). 特种纤维通常使用一层涂层.
耐高温丙烯酸酯
High-temperature acrylate is used because of its resistance to steam 和 电缆 gels or when the fiber will be used in a harsh environment requiring extra protection. 通常用于 工业传感 和 军事/航空航天应用.
Fluoroacrylate
无毒,坚固耐用,这种涂层是理想的医疗应用. It adheres to the class surface of the silica “healing” micro-defects thereby improving the tensile strength of the fiber 和 retarding static fatigue. Used in industrial 应用程序 where the hard polymer enables a connector to be crimped directly onto the fiber 和 the fiber cleaved mechanically. 更多beat365登录OFS HCS卷曲的信息 & 切割技术可以在这个网站上找到. 氟丙烯酸酯可作为包层或涂层材料用于 光纤.
有机硅涂料
抗水蒸气和一系列化学物质, 硅胶是柔软的, 并且需要缓冲来保护, 通常使用热塑性塑料,如ETFE, PFA或PEEK. 硅树脂可以抑制衰减导致的压缩,并且很容易剥离.
丙烯酸酯涂料
通常用于包覆光纤 分布式温度传感 应用程序. 取决于丙烯酸酯的等级, mid-temperature range up to 135 ºC for up to 20 years 和 higher temperatures up to 200 ºC, 可以支持. Optical fibers using this coating combination are protected against moisture across the temperature range. They are resistant to water 和 chemicals 和 are cushioned for deployment 和 service in harsh environments.
聚酰亚胺
聚酰亚胺 coatings from OFS are designed for 光纤 in harsh temperature sensing 和 communications environments. 一个瘦, hard polymer coating provides mechanically strong fiber with 优异的耐化学性, 小横截面, 以及长期高温暴露. OFS polyimide provides excellent thermal stability 和 some of the highest operating temperatures: continuous lifetime temperatures of 275 °C for up to 80 years, 300°C,长达13年, 325°C,最高可达2.2年,以及高达450°C的短期(24小时)短途旅行.
碳
这种涂料, 涂上几埃厚, extends fiber lifetime significantly 和 can be used with other coating materials. 用于光纤将暴露在高应力下的应用, 和/或安装在一个紧密的线圈, 而且/或者会暴露在高湿度的环境中. Often the coating of choice when long lifetime of the 光纤 is a requirement.
Polyetheretherketone偷看
Frequently used as a tertiary layer where other coatings like carbon 和 silicone may comprise other layers. PEEK provides a high Young’s modulus outer layer with excellent chemical 和 abrasion resistance, 低热膨胀, 是一种零卤素材料,具有低烟雾和低毒性.
聚对苯二甲酸丁二酯PBT
Polybutylene Terephthalate (PBT) delivers excellent short-term mechanical properties, 如高强度, 韧性和刚度以及良好的实际影响. PBT’s high heat-deflection temperatures 和 high temperature index ratings help components withst和 both short term thermal excursions 和 long-term heat exposure. 它对多种化学物质具有强大的耐化学性. Optical fibers 和 fiber optic 电缆s jacketed with PBT would be used in aerospace, 公用事业和工业应用.
聚丙烯PP
聚丙烯可用作…的替代品 聚氯乙烯 (PVC)作为光纤的缓冲材料 LSZH 电缆. 它散发的烟雾少,没有有毒的卤素, 在高温条件下,哪些可能导致酸的产生.
聚乙烯PE
PE has excellent properties of moisture 和 weather resistance 和 has good electrical properties over a wide temperature range. 它也很耐磨. 通常用作外部植物光纤电缆的护套材料.
LSZH(低烟、零卤)PE-PP
LSZH jacket is free of halogenated materials which can be transformed into toxic 和 corrosive matter during combustion. LSZH是封闭安装的良好电缆护套选择.
聚氯乙烯PVC
PVC通常成本低,灵活,相当坚固. 它可以在各种环境和应用程序中发挥作用. 用于室内和室外电缆的电缆护套材料.
聚偏氟乙烯PVDF
PVDF涂层不与大多数溶剂和化学品发生反应. 它具有优异的耐磨损性, 高介电强度, 耐风化, 并且在发生火灾时可以自行熄灭. 如果发生火灾,它们也不会产生太多的烟雾. 这种涂层是室内通风电缆的好选择.
聚氨酯TPU
TPU的性能包括:高耐磨性, 低温性能, 高抗剪强度, 高弹性, 透明度和耐油脂性. 用于工业级电缆.
无卤阻燃聚氨酯HFFR
无卤, flame retardant (HFFR) thermoplastic polyurethane (TPU) compositions are replacing halogen-containing, 阻燃TPU组合物在许多应用,包括, 但不限于, the insulation 和 protective jackets for the wire 和 电缆 associated with personal electronic devices 和 电缆s deployed in enclosed spaces. These HFFR TPU compositions can provide excellent flame-retardant performance 和 mechanical properties including excellent flexibility.
