- Optical fiber is a barrel of optical fiber, a light-conducting tool that uses the principle of total reflection of light in fibers made of glass or plastic.
- the beam is transmitted within the fiber, the signal is immune to electromagnetic interference, and the transmission is stable.
- the optical fiber has the characteristics of reliable performance, high quality, high speed, low line loss and long transmission distance, and is suitable for high-speed networks and backbone networks.
- the optical fiber generally includes a core and at least one coating over the core.
- the core 1 includes a glass fiber 2 and a cladding 3 coated on the outside of the glass fiber 2.
- Conventional fibers are typically coated with two layers of overlapping UV curable coatings which together form the undercoat layer.
- the coating contacting the surface of the core in the undercoat layer is called the inner layer 4, and the coating covering the inner layer 4 is called the outer layer 5.
- the outer layer 5 For marking the use of the optical fiber, etc., it is also possible to coat the outer layer 5 with a coating.
- Layer of ink layer Referring to Figure 2, a plurality of fibers can be coated and taped, and the coating is referred to as a tape layer 7.
- the resin used to form the inner layer 4 needs to meet low water penetration, has mechanical properties adapted to different environments, has a fast UV curing speed, has a long service life, and has a low glass transition temperature to ensure excellent low temperature resistance. Excellent requirements, good peeling performance, and small additional loss of fiber.

说 明 书 一种光纤及该光纤的制造方法与鉴别方法
本申请要求于 2013年 3月 7日提交中国专利局、申请号为 201310073267.9、 发明名称为 "一种光纤及其制造方法与鉴别方法" 的中国专利申请的优先权, 其全部内容通过引用结合在本申请中。 技术领域
本发明涉及光纤领域, 特别涉及一种光纤及该光纤的制造方法与鉴别方 法。 背景技术
光纤是光导纤维的筒写, 是一种利用光在玻璃或塑料制成的纤维中的全反 射原理而达成的光传导工具。 光束在光纤内传输, 信号不受电磁的干扰, 传输稳 定。 光纤具有性能可靠、 质量高、 速度快、 线路损耗低、 传输距离远等特点, 适高速网络和骨干网。
光纤一般包括纤芯及包覆在纤芯外的至少一层涂层。 参见图 1 , 纤芯 1包 括玻璃纤维 2及包覆在玻璃纤维 2外的包层 3。 通常的光纤一般涂敷有两层重 叠的可紫外固化涂层, 由它们共同构成底涂层。 参见图 1 , 底涂层中接触纤芯 表面的涂层叫做内层 4, 而覆盖在内层 4上面的涂层叫做外层 5 , 为了标记光 纤用途等, 还可以在外层 5外涂覆一层油墨层。 参见图 2, 多根光纤可以通过 涂层并带, 该涂层称为并带层 7。 用于形成内层 4的树脂需要满足水渗透低, 具有适应不同环境的力学性能, 紫外光固化速度快、 使用寿命长, 玻璃化转变 温度较低、 以保证其具有优良的耐低温性能, 附着力优异、 又具有合适的剥离 性能, 光纤的附加损耗较小等要求。 而用于形成外层 5的树脂要求其能给光纤 带来良好的机械性能和抗水解性能, 保护光纤不受外界环境损坏, 要求其具有 较高的模量、 高的玻璃化转变温度、 良好的耐水性以及耐热性。 目前市场上所 用的光纤涂层涂料从涂料所用树脂主体结构来看基本上大同小异,通过肉眼观 察等常规手段 4艮难进行区分。 而一般玻璃纤维直径为 125um, 外包内层 4和外 层 5涂层材料后直径为 250um,非常纤细,光纤制造商也难以在光纤上 "留下" 显而易见的标记。 因此, 如果只是进行目测, 艮难对光纤进行鉴别和区分, 即
使是专家也会将质量上完全处于两个不同级别的光纤判定为 "看起来完全一 样,,。
目前, 通常通过光纤识别技术对光纤进行区分。 已用的光纤识别技术有通 过红外谱图识别光纤涂层的方法, 具体为: 在光纤涂层中添加一定量的标记物 (例如丙烯腈), 根据光纤涂层在红外谱图中特定位置所出的特征峰对光纤涂 层进行标记识别; 另外还有通过光纤涂层折光率的差异对光纤涂层进行标记的 方法。
在实现本发明的过程中, 发明人发现现有技术至少存在以下问题: 红外谱图识别光纤涂层的方法所用的标记物在一定程度上会影响光纤本 身的性能, 同时在光纤储存和使用过程中该类标记物会有一定程度的挥发, 对 环境和人体造成危害; 通过光纤涂层折光率的差异对光纤涂层进行标记的方法 步骤比较繁瑣。 发明内容

另一方面, 提供了一种上述光纤的制造方法, 所述制造方法包括: 向制备好的至少一种光纤涂层涂料中添加显色指示剂,搅拌至所述显色指 示剂完全溶解, 得到含有指示剂的涂料;
将所述含有指示剂的涂料及其他各涂层的涂料涂覆、 拉丝固化到纤芯表 面, 形成所述光纤。
另一方面, 提供了一种上述光纤的鉴别方法, 所述鉴别方法包括: 截取部分光纤, 将所述光纤的涂层剥离下来作为待测样本;
配制显色液;
将所述待测样本浸泡在所述显色液中,静置一段时间后观察所述显色液的 颜色变化;
若所述显色液颜色发生变化, 则所述待测样本为涂层含有显色指示剂的光 纤。

具体地, 所述显色剂中有效物质的质量浓度为 0.01-10%。
本发明原理:
通过向光纤涂层中添加显色指示剂标记光纤的方法是利用了显色指示剂 遇到特殊环境会变色的原理。 所述的指示剂属于化学试剂的一类, 在一定介质 条件下, 其颜色会发生变化、 或者会产生混浊和沉淀, 或者有荧光现象等。 指 示剂通常用来检验溶液的酸碱性、 指示滴定终点、 检测环境中的有害物质等, 一般分为酸碱指示剂、 氧化还原指示剂、 络合指示剂。
酸碱指示剂: 指示溶液中 H+浓度的变化, 是一种有机弱酸或有机弱碱, 其 酸性和碱性具有不同的颜色。

氧化还原指示剂: 为氧化剂或还原剂, 它的氧化形与还原形具有不同的颜 色 , 在被氧化(或还原) 时, 即变色, 指示出溶液电位的变化
本发明实施例提供的技术方案带来的有益效果是:
生产光纤时通过在光纤涂层中添加显色指示剂, 对光纤涂层加以标记, 进 而对光纤加以标记。 该指示剂遇到相应显色液会发生显色反应使显色液显色, 由于其他光纤不具备该性质, 通过显色反应就能容易的鉴别所述光纤, 方便对 所述光纤进行标记和保护。 显色指示剂对环境友好, 不会造成环境污染。 显色 反应操作筒便快捷且灵敏度高, 只需要少量的显色指示剂即可显色, 因而显色 指示剂的加入量较少, 不会对光纤涂层的性能造成任何影响。 附图说明
