    • A method for encapsulating optical fibers (26, FIG. 2) comprises the steps of bonding optical fiber to a first surface of a rigid flat member (17) and placing the flat member in a substantially air-tight chamber (10, FIG. 1). An encapsulating sheet (13) is located in the air-tight chamber, such that it faces the flat member. The air pressure on the flat member is then made to be significantly lower than the air pressure on the encapsulating sheet, thereby to cause the encapsulating sheet (13) to press against the flat member (17, FIG. 3). The encapsulating sheet is made of a flexible flame-resistant material that maintains its structural integrity and does not melt or ignite at temperatures of at least two hundred degrees Centigrade. For example, the encapsulating sheet may be of Kapton (a trademark), doped Mylar (a trademark) or aluminum foil. The encapsulating sheet (13) is bonded to the flat member by an adhesive (31, FIG. 2) so that, after the sheet has been pressed against the optical fibers (26), it thereafter permanently supports each optical fiber in its assigned position.
    • 一种用于封装光纤的方法(图2中的26)包括以下步骤:将光纤接合到刚性平坦部件(17)的第一表面,并将平坦部件放置在基本上不透气的室(图1中的10) )。 密封片(13)位于气密室中,使得其面向平坦构件。 然后将平坦部件上的空气压力显着地低于封装片上的空气压力,从而使密封片(13)压靠在平坦部件(图3中的17)上。 密封片由柔性阻燃材料制成,其保持其结构完整性,并且在至少二百摄氏度的温度下不熔化或点燃。 例如,封装片可以是Kapton(商标),掺杂的Mylar(商标)或铝箔。 密封片(13)通过粘合剂(31,图2)粘合到平坦构件上,使得在片材被压靠在光纤(26)之后,其后将每个光纤永久地支撑在其指定位置 。

    • A plurality of optical fibers (13) are first bonded to an upper surface of a flat flexible plastic substrate (12). The optical fibers are covered with a layer (20) of thermoplastic material to form a composite structure comprising the thermoplastic material, the optical fibers and the plastic substrate. The composite structure is then compressed at a first elevated temperature and at a first relatively high pressure which are sufficient to bond or tack the thermoplastic material to the plastic substrate. The temperature of a composite structure is then cool while maintaining the first relatively high pressure. Thereafter, a second elevated temperature is applied to the thermoplastic material while compressing the composite structure at a second pressure. The second elevated temperature is higher than the first temperature and is sufficiently high to cause the thermoplastic material to flow about and encase the optical fibers, while the second pressure is smaller than the first pressure and is sufficiently small to avoid damaging said optical fibers. The various compression steps are applied by upper (17) and lower (16) platens of a press machine which are appropriately heated to apply the temperatures described above.
    • 首先将多根光纤(13)接合到扁平柔性塑料基板(12)的上表面。 光纤被热塑性材料层(20)覆盖以形成包括热塑性材料,光纤和塑料基底的复合结构。 然后将复合结构在第一高温和第一相对较高的压力下压缩,该第一高温足以将热塑性材料粘合或粘合到塑料基材上。 然后将复合结构的温度保持在第一相对高的压力下。 此后,在第二压力下压缩复合结构体时,将第二高温施加到热塑性材料上。 第二升高温度高于第一温度,并且足够高以使热塑性材料流动并包围光纤,而第二压力小于第一压力,并且足够小以避免损坏所述光纤。 通过适当加热的压力机的上部(17)和下部(16)压板施加各种压缩步骤以施加上述温度。
