SM-GSF-8/130-M, Matched Passive Single Mode Fiber
Coherent's SM-GSF-8/130-M fibers are designed for passive applications requiring single-mode operation and seamless integration with active fibers. Featuring an 8 µm core diameter and a 130 µm cladding diameter, these fibers ensure low splice loss and exceptional beam quality. The matched (M) design enhances compatibility, while the NuCOAT fluoroacrylate coating provides superior environmental durability and long-term reliability. These fibers are suitable for industrial, medical, and defense applications.
