Wavelength Division Multiplexing (WDM) is a highly efficient optical transmission technology that significantly improves fiber bandwidth utilization by transmitting multiple optical signals of different wavelengths through a single fiber. HUAJIAYU's WDM solutions primarily consist of Multiplexers (MUX) and Demultiplexers (DEMUX):
MUX: Combines multiple wavelength signals into a single fiber at the transmitting end.
DEMUX: Separates multiplexed signals into individual wavelengths at the receiving end.
WDM technology is widely used in telecommunications, data centers, and 5G fronthaul networks, enabling customers to expand capacity without deploying additional fibers.
HUAJIAYU offers a complete WDM product portfolio, including CWDM (Coarse WDM), DWDM (Dense WDM), and CCWDM (Compact CWDM), catering to diverse application scenarios:
Technology | Channel Spacing | Transmission Distance | Bandwidth Capacity | Typical Applications | HUAJIAYU Advantages |
---|---|---|---|---|---|
CWDM | 20nm | Short (<80km) | Medium | Enterprise networks, Metro access | Low cost, uncooled lasers |
DWDM | 0.8/0.4nm | Long (>100km) | Ultra-high | Core networks, DCI | High density, scalability |
CCWDM | 20nm | Short (<80km) | Medium | 5G fronthaul, PON | Ultra-compact, low insertion loss |
HUAJIAYU recommends customers consider the following key factors when selecting the optimal solution:
Transmission Distance
Budget Constraints
Space Limitations
CCWDM: HUAJIAYU's CCWDM modules utilize free-space optics, reducing size by 50% compared to traditional CWDM, making them perfect for space-constrained deployments like 5G base stations.
HUAJIAYU's CCWDM (Compact CWDM) solutions leverage Thin-Film Filter (TFF) technology, offering superior performance over conventional CWDM:
* Ultra-Compact Design: 50% smaller footprint for high-density installations
* Low Insertion Loss: Optimized optical design with <1.5dB loss
* High Stability: Operating range of -40°C to 85°C for harsh environments
* Plug-and-Play: Compatible with telecom, enterprise, and PON networks
To ensure optimal performance, HUAJIAYU engineers advise customers to consider:
* Wavelength Planning: Avoid interference (e.g., CWDM standard 18-channel grid, DWDM C-band expansion)
* Channel Spacing Optimization: Strict control of 0.8nm/0.4nm spacing for DWDM
* Optical Component Quality: HUAJIAYU provides low-PDL filters and high-precision lasers
As a leading optical communication solutions provider, HUAJIAYU delivers customized WDM systems for enterprises, carriers, and data centers. Whether you need cost-effective CWDM, high-capacity DWDM, or space-saving CCWDM, our solutions ensure high performance and reliability.
