Dual Window Coupler
Product Description
The Dual Window Coupler is a high-performance passive optical component engineered with dual-wavelength matching technology, designed to deliver consistent performance across the two core communication windows (1310 nm and 1550 nm) in optical networks. Its operating bandwidth is configurable: standard models support ±40 nm bandwidth, while ultra-broadband variants extend to ±80 nm - ensuring compatibility with diverse signal transmission demands.
A key advantage of this coupler is its stable splitting ratio across 1310 nm and 1550 nm, paired with low excess loss and low polarization-dependent loss (PDL). This dual-window compatibility eliminates the need for separate components for different wavelength systems, making it a cost-effective and versatile solution for optical communication systems, CATV networks, FTTH/FTTx infrastructure, and passive optical networks (PON).
Key Features
• Low Insertion Loss & Excess Loss: Minimizes signal attenuation to maximize optical power efficiency in transmission links.
• Low Polarization-Dependent Loss (PDL): Reduces polarization-induced signal distortion, ensuring stable transmission quality.
• Dual Operating Windows (1310 nm / 1550 nm): Eliminates the need for wavelength-specific components, simplifying network design and reducing costs.
• Broad Bandwidth Options: Standard (±40 nm) and ultra-broadband (±80 nm) models adapt to diverse system requirements.
• High Stability & Reliability: Maintains consistent performance under varying temperature/humidity conditions, suitable for long-term deployment.
