Nine fiber pigtail
The Nine Fiber Pigtail is a compact and reliable fiber optic solution designed for applications requiring low insertion loss, wide bandwidth, and minimal polarization-dependent loss. It features an epoxy-free optical path for enhanced long-term performance and is available in both P and A grades to meet varying system requirements. Compatible with wavelengths from 1250–1650 nm, including 1310 nm and 1550 nm, this pigtail supports various fiber types such as SMF-28E, OM3/OM4 multimode, and 50/125μm fibers. It is widely used in isolators, circulators, WDM systems, optical sensing, VR, and fiber optic slip rings. Multiple connector types and fiber lengths are available for flexible integration.
