DBC RATIO 20:80 SPLITTER

DBC RATIO 20:80 SPLITTER

৳ 120

The DBC 20:80 Asymmetric Fiber Splitter is a high-precision, passive optical component designed for efficient power distribution in standard Passive Optical Networks (PON). This Fused Biconical Taper (FBT) splitter provides a specific asymmetrical split, tapping off 20% of the optical power for a local node while preserving 80% of the signal for onward transmission. It is the perfect solution for 'bus' or 'daisy-chain' topologies common in FTTH (Fiber to the Home) and CATV distribution systems.

Streamline your network architecture and maximize its reach with the DBC 20:80 Asymmetric Ratio Splitter. Engineered for specialized architectures where precise power conservation is key to ensuring network performance over large geographical areas, this FBT splitter offers unparalleled reliability.

Smart Power Budgeting: By utilizing an asymmetric 20:80 split, service providers can 'drop' a signal to a single subscriber, access point, or small node using 20% of the optical power. The remaining 80% 'through' power continues down the line, serving multiple distant customers.

Exceptionally Low Through Loss: The 'through' port (80%) offers minimal signal degradation (≤ 1.15 dB), allowing for consistent, high-speed data and crystal-clear CATV signal distribution even after multiple split points in a bus topology.

Broad Wavelength Compatibility: Fully operational across all standard PON wavelengths (1310/1490/1550nm), making it compatible with GPON, EPON, and BPON systems.

Rugged and Stable Performance: Designed to perform consistently in harsh outdoor environments, maintaining stable operation across a wide temperature range for maximum network uptime.

Ultra-Compact Form Factor: The space-saving steel tube housing allows for seamless integration into existing fiber distribution boxes, splice closures, or patch panels, regardless of limited space.
