Hermetic Sealing Fiber Array

https://www.meisuoptics.com/products/hermetic-sealing-fa-fiber-array/

MEISU's hermetic sealing fiber array is realized by gold-coating the fiber cladding before inserting them into a metal (KOVAR) tube. Gap between fibers and tube is fully filled with sodering tin. The metal (KOVAR) tube of MEISU's hermetic sealing fiber is gold-coated as well to prevent it from oxidization. Such linear fiber array is commonly used in optical devices and modules that require air-tight packaging. The gold-coated Kover tube is easy to be fixed in optical devices using soldering tin and achieve air-tightness.
