OFS有能力为您的光纤解决方案提供各种涂层，以满足您的关键应用要求. 以下是一些可以与我们的涂料技术人员进一步讨论的选项.
What is an Optical Fiber Coating/Buffer?
光纤涂层/缓冲器在保护光纤免受预期环境影响方面起着重要作用. 涂层保护玻璃纤维在应用中免受机械和环境应力. The primary coating may be applied in a single or dual layer. 涂层是在纤维拉伸过程中和接触任何外部表面之前应用的. For additional protection, a layer of buffer material may be added. 缓冲材料为光纤提供额外的机械保护，并有助于保存波导.
What is a Fiber Optic Cable Jacket?
An optical cable structure protects optical fibers from environmental damage. Cable structure includes buffers, strength members, and jackets. Many factors influence the design of fiber-optic cables. The cable design relates to the intended application of the cable.
Fiber Optic Cable Layers
Fiber Optic Coatings:
Acrylate Fiber Coating
适于为光学玻璃纤维提供初级涂层的光固化液体涂层组合物. 标准电信光纤使用丙烯酸酯的双重涂层(较软的内涂层和较硬的外层). Specialty fibers typically use one coat.
High-Temperature Acrylate
使用高温丙烯酸酯是因为它耐蒸汽和电缆凝胶，或者当光纤将在需要额外保护的恶劣环境中使用时. Typically used in industrial sensing and military/aerospace applications.
Fluoroacrylate
Non-toxic and rugged, this coating is ideal for medical applications. 它粘附在二氧化硅类表面“愈合”微缺陷，从而提高纤维的抗拉强度，延缓静疲劳. 用于工业应用中，硬聚合物使连接器能够直接压接到纤维上，并机械地切割纤维. More information on OFS HCS Crimp & Cleave technology can be found on this website. This fluoroacrylate may be used as a cladding or a coating material for optical fiber.
Silicone Coating
Resistant to water vapor and a range of chemicals, silicone is soft, and requires buffering for protection, usually with thermoplastics like ETFE, PFA or PEEK. Silicone dampens attenuation inducing compression and is easily strippable.
Acrylate Coating
Typically used to coat optical fibers designed for distributed temperature sensing applications. Depending on the grade of Acrylate, 中温范围可达135ºC长达20年，更高温度可达200ºC, can be supported. 使用这种涂层组合的光纤在整个温度范围内都可以防止潮湿. 它们具有耐水和化学品的性能，并且可以在恶劣环境中部署和使用.
Polyimide
OFS的聚酰亚胺涂层专为苛刻的温度传感和通信环境中的光纤设计. A thin, 硬聚合物涂层提供机械强度高的纤维，具有优异的耐化学性, small cross-section, and long-term high-temperature exposure. OFS聚酰亚胺具有优异的热稳定性和一些最高的工作温度:275°C的连续使用寿命温度长达80年, 300 °C for up to 13 years, 325 °C for up to 2.2 years, as well as short-term (24 hours) excursions as high as 450 °C.
Carbon
This coating, applied a few angstroms thick, 显著延长纤维寿命，可与其他涂层材料配合使用. Used in applications where the optical fiber will be exposed to high stress, and/or installed in a tight coil, and/or there will be exposure to high humidity. 当光纤有长寿命的要求时，通常选择涂层.
Polyetheretherketone PEEK
通常用作第三层，其中其他涂层如碳和硅可能包含其他层. PEEK提供高杨氏模量的外层，具有优异的耐化学性和耐磨性, low thermal expansion, and is a zero-halogen material providing low smoke and toxicity.
Polybutylene terephthalate PBT
聚对苯二甲酸丁二酯(PBT)具有优异的短期机械性能, such as high strength, toughness and stiffness as well as good practical impact. PBT的高热偏转温度和高温指数额定值有助于组件承受短期热漂移和长期热暴露. It has robust chemical resistance to a wide range of chemicals. 用PBT包覆的光纤和光缆将用于航空航天, utilities and industrial applications.
Polypropylene PP
Polypropylene may be used as an alternative to polyvinyl chloride (PVC) as a buffer for optical fiber in LSZH cable. It emits less smoke and no toxic halogens, which may lead to production of acid in high-temperature conditions.
Polyethylene PE
PE具有优异的防潮和耐候性，在较宽的温度范围内具有良好的电性能. It’s also abrasion resistant. Typically used as a jacket material for Outside Plant fiber optic cables.
LSZH (low-smoke, zero halogen) PE-PP
LSZH夹套不含卤化物质，卤化物质在燃烧过程中会转化为有毒和腐蚀性物质. LSZH is a good cable jacket choice for enclosed installations.
Polyvinylchloride PVC
PVC is usually low-cost, flexible, fairly rugged. It can be formulated to function in a variety of environments and applications. It is used as a cable jacket material for both indoor and outdoor cables.
Polyvinylidene Fluoride PVDF
A PVDF coating does not react with most solvents and chemicals. It offers excellent resistance to abrasions and wear, high dielectric strength, is resistant to weathering, and can extinguish itself in the case of a fire. They also do not produce much smoke if there is a fire. This coating is a good choice for indoor plenum cables.
Polyurethane TPU
Properties of TPU include: high abrasion resistance, low-temperature performance, high shear strength, high elasticity, transparency and oil and grease resistance. Used in industrial grade cables.
Halogen free Flame retardant Polyurethane HFFR
Halogen-free, 阻燃(HFFR)热塑性聚氨酯(TPU)组合物正在取代含卤材料, flame retardant TPU compositions in a number of applications including, but not limited to, 与个人电子设备和部署在封闭空间的电缆有关的电线电缆的绝缘和保护套. 这些HFFR TPU组合物可以提供优异的阻燃性能和机械性能，包括优异的柔韧性.
Hytrel® TPE
热塑性聚酯弹性体(TPE)提供橡胶的柔韧性和塑料的强度. The material offers excellent flex fatigue and broad use temperature. It resists tearing, flex-cut growth, creep and abrasion, 具有优异的韧性，可抵抗碳氢化合物和许多其他流体. 它被用于飞机应用中可靠使用的几种OFS电缆.
Ethylene tetrafluoroethylene ETFE
ETFE[聚乙烯-共四氟乙烯]具有极好的耐极端温度性能, excellent chemical resistance, good mechanical strength with excellent tensile strength and elongation. It has superior physical properties compared to most fluoropolymers. It also exhibits outstanding resistance to weather and aging. ETFE通常用作工业数据通信应用中使用的OFS HCS®光纤的缓冲器.
Perfluoroalkoxy Teflon™ PFA
Optical fiber cables 用Teflon™含氟聚合物缓冲，获得卓越的耐高温性能, chemical reaction, corrosion, and stress cracking. The material is well suited for cables deployed in harsh applications.
