Written By Whitney Morris

LIEKKI® Passive-4/125(-PM), 0.22NA fibers are designed to support LIEKKI® Er-doped “4/125” fibers in a wide range of applications. The passive fibers are available as non-PM (LIEKKI® Passive-4/125, 0.22NA) and PM (LIEKKI® Passive-4/125-PM, 0.22NA) versions. The passive fibers have mode field diameters matched to LIEKKI® Er-doped “4/125” fibers are designed with normal dispersion at 1550nm. 

Features

  • Compatibility:
    Designed to match to LIEKKI® Er-doped “4/125” fibers in mode field diameter and dispersion properties
    Normal dispersion (nominal: -15ps/(nm*km))

  • Reliability:
    Single cladding fibers feature a telecom grade dual layer high-index acrylate coating

Applications

  • Fiber-based components for Er-doped fiber lasers and amplifiers

  • Fiber dispersion management for fiber lasers and amplifiers
