In this era of rapid digital transformation, high-speed, stable, and cost-effective network transmission solutions have become pivotal in driving business growth for enterprises. We understand your needs for enhancing network bandwidth, reducing operational costs, and achieving rapid business deployment. Therefore, we are delighted to introduce two leading 100G DWDM products, along with our cost-effective wavelength division multiplexing (WDM) subsystem solution, aiming to bring an unprecedented upgrade experience to your network architecture.

100G QSFP28 PSM DWDM4 – C-BAND
The Powerhouse for Long-Distance Transmission

Technical Highlights: The 100G QSFP28 PSM DWDM4 – C-BAND employs a four-carrier Color ZR+ C-BAND design. It features 4x25G C-band 100GHz DWDM EML lasers at the transmitter and efficient PIN detectors at the receiver. With support from DCM dispersion compensation and EDFA amplification, it ensures a transmission distance of at least 80km. The MPO-12 interface design simplifies fiber connections, and the total power consumption is below 5W, making it both environmentally friendly and efficient.
Application Scenarios: Ideal for long-distance transmission needs such as 100G Ethernet metropolitan access and point-to-point access networks, providing stable and reliable data transmission channels for operators and enterprises.
One-Stop Solution: Paired with GIGALIGHT’s self-developed intelligent 1U optical layer equipment, including DWDM EDFA, AAWG, and tunable TDM or fixed DCM, it offers customers a complete non-coherent DWDM transmission solution from optical transceivers to optical layer equipment, accelerating business deployment.

100G QSFP28 DWDM1 O-BAND
The Cost-Effective Choice for Short-Distance Transmission

Technical Highlights: The 100G QSFP28 DWDM1 O-BAND silicon photonics module adopts PAM4 modulation mode, supporting a full range of 16 wavelengths covering the O-Band DWDM with a 200GHz wavelength spacing. The O-Band’s natural low-dispersion characteristics reduce signal distortion, eliminating the need for additional dispersion compensation. With a power consumption below 3.5W, it is 20% lower than similar products, contributing to green data center construction.
Application Scenarios: Widely used in medium-to-short-distance transmission scenarios such as metropolitan access and aggregation networks, inter-data center interconnectivity (DCI), and 5G front-haul, providing cost-effective solutions for 5G networks, enterprise private lines, and distributed computing power.
Flexible Adaptability: Decoupled from white-box equipment, it enhances network deployment flexibility and meets customers’ needs for open optical networks.

Cost-Effective WDM Subsystem Solution: The Ultimate Pursuit of Cost Efficiency
GIGALIGHT’s cost-effective WDM subsystem solution focuses on the application of non-coherent DWDM technology, achieving short-distance, high-capacity transmission by simplifying the optical layer design and reducing costs. This solution is particularly suitable for scenarios that are cost-sensitive and have low requirements for transmission distance, such as DCI, 5G, and enterprise private networks.
Core Advantages:
- Cost Efficiency: Hardware costs can be reduced by 30%~50% compared to coherent DWDM solutions, along with reduced deployment and maintenance costs.
- Short-Distance High-Speed Transmission: Leveraging advanced modulation technologies like PAM4, it achieves single-wavelength 100G~400G short-distance transmission, meeting high-speed data transmission needs.
- Simplified Operations and Maintenance: Reduces reliance on complex optical layer management, enhancing system reliability and lowering operational difficulty.
- Green Communication: Low-power design aligns with the trend of low-carbon communication, contributing to the realization of “dual carbon” goals.
GIGALIGHT believes that by introducing our 100G DWDM products and cost-effective WDM subsystem solution, you will significantly enhance network performance, reduce operational costs, and accelerate business innovation.
