    • A hermetically sealable package may be formed from a top portion and a bottom portion mated along a seam at or near a plane of an optical fiber. A completed pill assembly may be positioned directly into the enclosure base without requiring the fiber to be threaded through the feed through or “snout”. The top potion may then be mated with the bottom portion to form the package. A glass solder ring may be placed coaxial with the fiber in the feed through. The seam may be sealed by laser welding and the glass solder ring reflowed by laser heating, for example, with a same laser as used to weld the seam or by resistive or induction heating. In some embodiments a coupling tube around the fiber and snout or the snout itself may have holes to allow solder sealing within the snout and filling the remaining area with epoxy. Since the package is initially split in two pieces, module assembly may be facilitated without threading.
    • 可以由沿着光纤平面处或附近的接缝配合的顶部和底部形成气密密封的封装。 完整的药丸组件可以直接定位到外壳基部中,而不需要将纤维穿过进料口或“鼻”。 然后可以将顶部部分与底部配合以形成包装。 玻璃焊环可以与进料通道中的纤维同轴放置。 接缝可以通过激光焊接密封,并且玻璃焊接环通过激光加热回流,例如,与用于焊接接缝或通过电阻或感应加热相同的激光器。 在一些实施例中,围绕纤维和鼻孔或鼻口本身的耦合管可具有孔,以允许焊缝在鼻孔内密封并用环氧树脂填充剩余区域。 由于包装最初分成两部分,所以可以在没有穿线的情况下方便地组装模块。
