Aluminum-coated single-mode optical fibers

Al-coated fibers
Al-coated fibers
Aluminum-coated single-mode optical fibers have all the benefits of optical fibers include increased mechanical strength and greater fatigue resistance compared to non-hermetic and polymer-clad fibers (PCS). Their transmittance covers a spectral range of 1500 to 1600 nm, and also remains stable in corrosive chemicals that normally react to silica glass.

FEATURES:
  • Excellent mechanical strength and flexibility compared to polymer coated fibers.
  • The temperature range is from -196C to +400C.
  • The metal coating can be soldered.
