49 fiber pigtail
The 49 Fiber Pigtail is a high-density, high-performance fiber optic component designed for applications demanding low insertion loss, wide bandwidth, and excellent polarization-dependent loss (PDL) performance. Featuring an epoxy-free optical path, it ensures long-term stability and reliability. Available in P Grade and A Grade, the pigtail supports key wavelengths including 1310 nm, 1550 nm, and broad-band 1250–1650 nm, and is compatible with SMF-28e single-mode fiber. It is widely used in isolators, circulators, WDM systems, optical sensing, VR, and fiber optic slip rings. Multiple connector options and customizable fiber lengths enable flexible and seamless integration into diverse optical systems.
