Products Overview
Gracyfiber’s Reflective WDM (High Isolation) is a miniature, high-performance bidirectional filter that seamlessly separates 1310 nm and 1550 nm signals in a single fiber—ideal for PON, 5G fronthaul, and hybrid access networks. With ≥50 dB transmission isolation, ultra-low insertion loss, and a compact Φ3.0 × 15 mm package, it enables space-efficient, cost-effective wavelength routing without active components.
Engineered for reliability and precision, this reflective WDM delivers exceptional signal integrity for applications demanding strict channel separation and minimal footprint.
