DBC RATIO 25:75 SPLITTER

DBC RATIO 25:75 SPLITTER

৳ 120

The DBC 25:75 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 25% of the optical power for a local node, subscriber, or drop-off, while preserving 75% 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 25:75 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 and predictable power management.

Smart Power Budgeting: By utilizing an asymmetric 25:75 split, service providers can 'drop' a

signal to a local subscriber, access point, or node using 25% of the optical power. The remaining 75% 'through' power continues down the line, serving multiple distant customers. This ratio provides more local power than lower tap ratios while still conserving substantial power for extended transmission.

Low Through Loss: The 'through' port (75%) offers minimal signal degradation (≤ 1.4 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.
