FOBER Fiber Optic Coupler FWDM – High-Performance Wavelength Multiplexing for Next-Gen Networks
The FOBER FWDM (Filter Wavelength Division Multiplexing) Fiber Optic Coupler is a precision-engineered passive device designed to combine or separate specific optical wavelengths in fiber-optic communication systems. Built to support triple-play networks, FTTH, CATV, and GPON/EPON applications, this advanced component allows simultaneous transmission of multiple signals over a single fiber line by managing wavelengths such as 1310 nm, 1490 nm, and 1550 nm.
This product reflects FOBER’s dedication to performance, quality, and innovation in optical network solutions. Its robust design, high isolation, and minimal insertion loss make it ideal for a wide range of fiber-optic deployments, from small-scale enterprises to large telecom infrastructures.
Key Features
Advanced Filter-Based WDM Technology
The FWDM coupler uses thin-film filters to selectively multiplex or de-multiplex different wavelengths with high precision, maintaining signal integrity across all channels.
Triple Wavelength Support
Supports the most common fiber-optic transmission wavelengths—1310 nm (data upstream), 1490 nm (data downstream), and 1550 nm (video/CATV signals). This enables efficient delivery of internet, voice, and video over a single fiber.
High Isolation & Low Insertion Loss
With insertion loss typically less than 1.0 dB and isolation levels over 30 dB, it ensures optimal signal separation and minimal interference for stable and high-quality transmission.
Wide Operating Temperature Range
Designed for harsh environments, the FWDM works reliably from -40°C to +85°C, making it suitable for both indoor and outdoor deployments.
Compact & Durable Construction
Available in steel tube or ABS box packaging, this device is compact, easy to install, and built to last, offering long-term performance with minimal maintenance.
Standard Connector Compatibility
Can be ordered with SC/APC, SC/UPC, LC/UPC, or LC/APC connectors, with single-mode fiber compatibility (typically G.657A or G.652D).
