With an ever-increasing demand for higher data throughput and limited fiber availability, the FOBER CWDM 4 Channel MUX provides a cost-effective and scalable solution. It minimizes infrastructure investments while delivering excellent performance, long-term durability, and seamless integration with CWDM-compatible equipment.
Key Features
4 Independent CWDM Wavelength Channels
The device allows simultaneous transmission of up to four signals across different CWDM wavelengths, typically spaced 20 nm apart (ranging from 1270 nm to 1610 nm). Each channel operates independently, enabling multi-service, multi-user operations over a single fiber.
Low Insertion Loss
Engineered for optimal efficiency, the multiplexer ensures minimal signal loss (typically ≤1.4 dB), helping preserve signal strength and quality over long distances.
High Channel Isolation
With channel isolation levels of ≥30 dB, the CWDM MUX prevents interference between wavelengths, ensuring clean and reliable signal separation and reducing cross-talk.
Compact and Durable Design
Available in ABS box, LGX cassette, and 19” rack-mount form factors, the multiplexer is easy to deploy in a variety of environments—from data centers to outdoor cabinets.
Passive Operation
As a fully passive device, it requires no power or cooling, making it highly energy-efficient and virtually maintenance-free.
Customizable Connectors
Compatible with various fiber connector types such as SC/APC, SC/UPC, LC/UPC, and others, based on specific deployment requirements.
