The DBC 30:70 Asymmetric Fiber Splitter is a high-precision, passive optical component engineered for optimized power distribution in Passive Optical Networks (PON). This Fused Biconical Taper (FBT) splitter provides an asymmetrical split, directing 30% of the optical power to a local drop-off or node while maintaining 70% of the signal strength for continued transmission. It is an essential component for efficient "bus" or "daisy-chain" topologies in FTTH (Fiber to the Home) and CATV networks.

The DBC 30:70 Asymmetric Ratio Splitter offers a balanced approach to power management in complex fiber architectures. It is designed specifically for service providers who need to deliver a stronger signal to a local subscriber or node while still preserving a high-integrity signal for downstream users.

Optimized Power Drop: The 30:70 ratio is ideal for nodes requiring slightly higher power than standard tap-offs, ensuring that even localized high-bandwidth demands are met without compromising the entire link.

High-Integrity Throughput: With 70% of the power continuing through the port (≤ 1.9 dB loss), this splitter allows for deep network penetration in daisy-chain configurations, supporting multiple users across a large area.

Universal PON Compatibility: Fully operational across 1310nm, 1490nm, and 1550nm wavelengths, making it a "plug-and-play" solution for GPON, EPON, and BPON systems.

Industrial Durability: Housed in a compact, rugged steel tube, it is built to withstand extreme temperatures and environmental stress inside fiber distribution boxes or outdoor splice closures.

Low Signal Noise: Engineered for low Polarization Dependent Loss (PDL) and high return loss, ensuring that data and CATV signals remain crystal clear.
