Description

一种超低损耗大有效面积光纤及其制备工艺
技术领域
本发明涉及一种光纤领域,特别涉及一种超低损耗大有效面积光纤及其制备工艺。
背景技术
光纤强度是超低损耗光纤关键指标之一,主要体现在筛选应变上,普通光纤的应变一般在1%左右来应对来自敷设和热胀冷缩引起的张力,而超低损耗光纤应用在超长距离光通讯链路中,常常需要跨越戈壁、深海等恶劣环境,从考虑敷设或环境温度变化时,所受到的张力相比于普通光缆更大,综合考虑《深海光缆》国家标准、敷设难度和使用寿命等方面,希望超低损耗光纤的应变达到2%甚至以上,能够完全满足光纤成缆和敷设的需要。
光纤的强度主要取决于裸光纤表面的微裂纹。光纤中为微裂纹主要来自拉丝炉内的杂质粒子。杂质粒子附着在光纤表面,在冷却过程中,形成裂纹和应力集中,光纤表面裂纹受大气环境中水分子作用而逐渐侵蚀,导致硅氧四面体结构被破坏,硅氧键的断裂会扩大微裂纹的范围,影响光纤强度。
拉丝炉长期工作后,炉内石墨件表面发生少量氧化使拉丝炉炉体表面变得粗糙,预制棒在高温下产生少量二氧化硅升华与拉丝炉炉体内表面反应生成坚硬的碳化硅微粒,并随炉内气流的影响在炉内漂浮。减少光纤拉丝炉内灰尘对光纤的影响。
光纤衰减系数除了受限于预制棒的制备过程,同时也受石英玻璃假想温度的影响。当石英光纤从软化温度降低到假想温度时,石英玻璃内部结构向平衡态转化。当石英温度低于假想温度后,光纤内部结构就被定型,很难再改变。如果光纤在到达假想温度时没有充分释放内应力,那么光纤由密度不均造成的瑞利散射则会显著影响光纤的衰减系数。
发明内容
本发明要解决的技术问题是提供一种超低损耗大有效面积光纤及其制备工艺。
为解决上述技术问题,本发明的技术方案为:一种超低损耗大有效面积光纤,其创新点在于:从内到外依次包括芯层、包层以及涂层,其特征在于:所述芯层为纯二氧化硅玻璃层,其半径为5~7μm,其不圆度为1.5%,所述包层包括内包层、中包层以及外包层,所述内包层为掺氟内包层,其半径r2为5~12μm,相对折射率差为-0.4~-0.2%,所述中包层半径r3为12~25μm,所述外包层为纯石英玻璃层,其半径r4为25~45μm,该包层整体不圆度为0.2%,所述涂层材料采用聚丙烯酸酯,包括内涂层以及外涂层,所述内涂层直径为192μm,其不圆度为0.6%,所述外涂层直径为245μm,其不圆度为0.8%。
进一步的,所述光纤在1550nm处的衰减系数小于等于0.165dB/km,在1625处的衰减系数小于等于0.19dB/km。
进一步的,所述光纤在1550nm处的不连续性小于等于0.05dB。
进一步的,所述光纤在1550nm处的模场直径为11.9~13.9μm,模场面积大于等于110μm2
进一步的,所述光纤在1550nm处的色散斜率小于等于0.07ps/nm2*km,色散系数小于等于22ps/nm*km。
进一步的,所述光纤在温度20~28之内,相对湿度在40%~60%之内,光纤抗疲劳参数大于25。
本发明的另一种技术方案为:一种超低损耗大有效面积光纤的制备工艺,步骤如下:
(1)预制棒制备:采用VAD+MCVD+OVD工艺,其中VAD工艺沉积芯棒,实现芯棒的快速沉积,显著降低光纤衰减;MCVD工艺实现包层折射率的下陷结构,采用OVD工艺沉积外包层,沉积速率高,有效降低生产成本;

具体实施方式
在高速大容量DWDM(密集波分复用)系统中,传统的G.652D光纤以及超低损耗光纤由于非线性效应,传输距离受到限制。随着各种新型编码方式(如RZ(归零码)等)、纠错技术(如FEC(前向纠错)、SFEC(超强前向纠错)等)的出现和各种低噪声放大器(如DRA(分布式拉曼光纤放大器)等)的发展,对DWDM系统的OSNR(光信噪比)容限要求和OSNR劣化有非常明显的改善,光纤损耗不再是限制系统传输的决定性因素。在目前DWDM系统中,非线性效应成为了当前高速光纤通信系统的主要限制因素。在光功率传输下,光纤会发生拉曼散射、克尔效应等非线性效应,影响光纤在强光场下的损耗系数和折射率变化。适用于DWDM 的光纤已有报道,纯石英纤芯的光纤具有较低的损耗,但制作较为复杂,有效面积增大意味着光纤应力附加损耗也随之增大。
超低损耗光纤是未来大容量光通讯发展的物质基础,是我国推行“宽带中国”的战略,实现400G超高速带宽的重要媒介。
超低损耗光纤由丙烯酸酯内外涂层、掺氟包层和纯硅芯层组成。芯层为纯二氧化硅玻璃层,其半径为5~7μm,其不圆度为1.5%,包层包括内包层、中包层以及外包层,内包层为掺氟内包层,其半径r2为5~12μm,相对折射率差为-0.4~-0.2%,中包层半径r3为12~25μm,外包层为纯石英玻璃层,其半径r4为25~45μm,该包层整体不圆度为0.2%,涂层材料采用聚丙烯酸酯,包括内涂层以及外涂层,内涂层直径为192μm,其不圆度为0.6%,外涂层直径为245μm,其不圆度为0.8%。
超低损耗光纤的主要技术指标如下表所示:
光纤的强度主要取决于裸光纤表面的微裂纹。光纤中为微裂纹主要来自拉丝炉内的杂质粒子。杂质粒子附着在光纤表面,在冷却过程中,形成裂纹和应力集中,光纤表面裂纹受大气环境中水分子作用而逐渐侵蚀,导致硅氧四面体结构被破坏,硅氧键的断裂会扩大微裂纹的范围,影响光纤强度。
拉丝炉长期工作后,炉内石墨件表面发生少量氧化使石墨件表面变得粗糙,预制棒在高温下产生少量二氧化硅升华与石墨件表面反应生成坚硬的碳化硅微粒,并随炉内气流的影响在炉内漂浮。拉丝炉炉体上端为炉顶气盘,下端为退火管,常规光纤拉丝炉惰性气体进气方式一般为上部平吹进气,惰性气体通过层流的方式自上而下通过拉丝炉内部进入退火管,这种进气方法的优点在于平缓的气流不会在引起拉丝炉内气流扰动,使炉灰沉积于石墨件内壁,减少炉灰与光纤接触的几率,但经过长时间的拉丝生产,石墨件内壁的炉灰积累到一定程度,其在高温扩散的影响下将会对光纤造成严重的影响导致拉丝中途强度骤变,影响光纤的质量和石墨件的使用寿命。
光纤衰减系数除了受限于预制棒的制备过程,同时也受石英玻璃假想温度的影响。当石英光纤从软化温度降低到假想温度时,石英玻璃内部结构向平衡态转化。当石英温度低于假想温度后,光纤内部结构就被定型,很难再改变。如果光纤在到达假想温度时没有充分释放内应力,那么光纤由密度不均造成的瑞利散射则会显著影响光纤的衰减系数。退火工艺的影响光纤的内应力,但是目前的退火炉内温度不均,容易造成光纤内应力释放不完全。
现有的光纤涂覆固化系统中,固化炉内一般要使用抽风系统,一方面降低紫外光固化炉内温度,延长紫外光固化炉寿命,另一方面抽取光纤表面涂层固化挥发物,提高光纤加工质量;同时,抽走有害气体,避免挥发物污染周围环境和造成人身危害,但同时抽风流量太大或太小又会影响光纤的固化效果,一般抽风流量都是在一个稳定的范围内。
当在实际生产过程中,一方面抽风管道在长时间的使用中容易堵塞,抽风量会减小,必须在停炉期间通过人工定期对抽风流量进行检测和调整,以保证正常使用的流量;另一方面,如果抽风流量调节太大或太小,则会影响光纤的固化效果。原有的固化工艺需要人工进行监控和调节,人为因素较多;另一方面光纤生产中途涂覆固化出现问题,必须强制终止生产才可以进行监控调节,正常生产时,无法监控抽风实际流量。
在超低损耗光纤的制备过程中,使用超低损耗光纤拉丝退火系统进行制备,预制棒从拉丝炉炉顶进入拉丝炉,拉丝炉炉体内部的温度为2000~2200℃,预制棒在拉丝炉炉体内熔融拉丝,牵引速度为≥2000m/min,拉丝炉上的温度炉顶气盘上的进气孔供应惰性气体进入拉丝炉;风向倾斜向下的进风孔能减小炉灰与光纤接触的几率,这样的进风孔具有平行设置的若干个,送风风向与竖直方向呈15~45°夹角;风向竖直向下的进气孔,吹扫拉丝炉炉体内壁,防止炉灰沉积在拉丝炉炉体;退火管中采用多孔分散式排气方式,漏斗形的设计有效防止炉灰沉积影响光纤强度,排出的炉灰通过软管连接至炉灰回收装置;光纤在退火管出口温度为1730°;光纤进入保温退火炉,保温退火炉中的每个加热元件由控制单元独立控制,形成800~1200℃的梯度温场。
光纤的散射损耗是光纤损耗的最大原因。光纤散射最重要的部分就是瑞利散射。瑞利散射是由光纤材料中折射率的微小不均匀所造成的,可知,由密度不均匀所产生的瑞利散射主要是由折射率n、假想温度Tf和等温压缩率βT所决定。这三个因素都受拉丝过程的影响。等温压缩率的大小与温度密切相关。当光纤温度高于假想温度时,玻璃粘度相对较小,低于10MPa 的应力就能够造成玻璃的密度改变;而当光纤温度低于假想温度时,需高达2000MPa 的应力才能影响玻璃的密度。因此,等温压缩率对瑞利散射的影响依赖于假想温度,光纤的假想温度主要由玻璃粘度和冷却速度所决定。对于光纤生产而言,玻璃的种类和粘度都已确定,则假想温度主要由光纤的冷却速度所决定,可知,光纤在固定拉丝速度下的实际温度和降温速率。通过加入保温退火炉温场,控制光纤出退火保温炉时的实际温度,保证光纤温度在1000℃以上,使光纤充分释放内应力。光纤降温速率随保温炉温场温度的升高而下降,当降温速率在5000k/s以下时,光纤内应力能够完全释放,消除由密度不均产生的瑞利散射达到降低光纤衰减的目的,同时如果保温温场设置过高,光纤出口温度高于1200℃进入环境时,有可能导致光纤包层受温度突变、而芯层仍然保持高温,容易导致内外在此产生应力,影响光纤衰减。另外过高的光纤出口温度使光纤冷却需要更大的能耗和冷却氦气,提高了光纤成本,因此将保温温场设置为800-1200℃。
由于采用不规则超低损耗大有小面积光纤预制棒拉丝,在拉丝炉内控制光纤熔融温度时加热温度会有适当微调,使光纤出退火管温度发生变化,此时需要设置合适的退火保温场温度来配合光纤出炉温度。该关键技术利用数据线连接保温炉电源和拉丝机主控计算机,实现保温炉温度远程控制,同时,结合实时炉温、实时拉丝速度和恒定的降温速率,计算保温炉合适温度进行自动微调控制。实现恒定的光纤退火最优温度。
光纤进入紫外光固化炉,一般生产环境温度20~28℃,环境湿度40~60%,紫外光固化炉功率控制在70~95%,紫外光固化炉内使用抽风系统,抽风系统包括抽风管道、检测装置以及控制单元B,检测装置包括安装在紫外光固化炉中的温度探测仪、安装在固化抽风管道内的风速检测仪以及自动调节阀门,控制单元B与检测装置电连接;将光纤表面涂层固化挥发物抽出,并抽走有害气体,温度探测仪检测到紫外光固化炉内的温度,同时将温度反馈至控制单元B,固化抽风管道中的风速检测仪检测到的风速流量也反馈至控制单元B,如果紫外光固化炉内温度及固化抽风管道中的风速流量全部在设定范围内,则光纤正常生产。如果反馈至控制单元B的紫外光固化炉内的温度波动,且固化抽风管道中的风速流量也产生对应的波动,则控制单元B 将控制调节自动调节阀门,改变抽风效果,若调节无效,或波动异常,则对外提示对设备进行保养维修。
紫外光固化炉抽风系统改进后:1、可以通过在线监控紫外光固化炉的抽风情况;2、通过在线监控紫外光固化炉的抽风,可以判断光纤的固化效果,通过光纤的固化质量,可以自动调节固化抽风;3、通过紫外光固化炉内的温度监控,与抽风调节,可以增加紫外光固化炉寿命;4、充分满足光纤拉丝过程中的紫外光固化炉挥发物的去除,增加光纤质量。
固化后的光纤经过筛选工序,即可完成加工。
