FS Automated DWDM Multiplexed Transmission Solution

As more services migrate to the cloud, data centers are increasingly deployed in a distributed manner and rely on WDM technologies for high-speed interconnection to ensure seamless, unified service delivery. The resulting surge in DCI traffic places immense pressure on existing network infrastructures. In today’s cost-sensitive environment, cloud operators are also striving to maximize the efficiency of land use, space, power, and fiber resources.

At the same time, as data centers grow in scale, traditional manual configuration and deployment methods struggle to meet the demands for rapid, efficient network rollout. The adoption of automation technologies has become essential, simplifying device deployment processes and significantly improving the network management efficiency of data center networks while reducing both construction and maintenance costs.

Key Challenges in DCI Deployment

1. Shortage of Skilled Personnel and Limited O&M Capabilities

While many enterprises and ISPs have strong IT expertise, they often lack in-depth knowledge of WDM and optical transmission technologies. Outsourced teams are typically unfamiliar with tasks such as remote site deployment, capacity expansion, and daily on-site maintenance. In large-scale networks with thousands of devices, limited manpower leads to delayed responses and inefficient troubleshooting.

2. Complex and Time-Consuming Deployment Processes

Traditional WDM systems involve complicated, multi-step manual operations—such as fiber patching, wavelength configuration, and power calibration—which often extend deployment cycles to several weeks. These processes are error-prone, especially with manual fiber connections, and heavily reliant on expert knowledge, making them unfit for the fast-paced demands of cloud-based services and frequent capacity upgrades.

3. Slow Fault Detection and Lack of Intelligent O&M Tools

Current DCI networks lack intelligent monitoring and root cause analysis. In many cases, service disruptions are detected by upper-layer applications before the DCI layer even registers a fault. The absence of real-time optical layer monitoring and predictive diagnostics leads to prolonged downtime and increased operational risks. A shift toward automated, proactive, and AI-driven O&M is urgently needed to enable faster fault identification and efficient recovery.

FS Automated DWDM Multiplexed Transmission Solution

To address the growing challenges of DCI deployment—such as high bandwidth demands, limited staffing, and complex operations—enterprises and service providers need a solution that combines performance, simplicity, and automation. FS responds to this need with a dual-fiber point-to-point DWDM solution that features a future-ready architecture with flexible support for both NRZ and coherent services. Powered by the feature-rich D5110-M40C4-ZR+, it supports up to 40 wavelengths at 400G each, delivering a total system capacity of up to 16Tbps. The solution supports WebGUI and the AmpCon-T management system to enable one-click provisioning, automatic wavelength tuning, and intelligent O&M—greatly simplifying deployment and reducing operational complexity.

Why Choose FS D5110-M40C4-ZR+ Based Solution?

Purpose-built for modern DCI scenarios, D5110-M40C4-ZR+ combines the compact footprint and plug-and-play simplicity of a passive multiplexer with the intelligence and capabilities of an active optical platform.

Unlike traditional passive muxes, it offers traffic monitoring, signal amplification for extended reach, and support for high-speed protocols including 400G coherent optics. This all-in-one design eliminates the need for multiple external components, making it an ideal foundation for open, scalable, and reliable line systems.

Ease of use is at the core of the platform. With remote network management via WebGUI and the AmpCon-T system, along with zero-touch provisioning and automated configuration, network teams—even those with only basic optical knowledge—can complete installation and bring up new services in minutes, not days.

Below are the key features and benefits of the FS solution:

High-Capacity Transmission to Meet Diverse Network Demands

The FS DWDM solution supports up to 40 wavelengths, each carrying up to 400G traffic, resulting in a total system capacity of up to 16Tbps. It is ideally suited for bandwidth-intensive applications such as data center interconnect (DCI) and metro transport. The solution supports both NRZ (1–10G) and coherent modulation formats (QPSK/8QAM/16QAM), ensuring compatibility with diverse service requirements and complex network environments.

Space-Saving, Highly Integrated Network Design

Combining the D5110-M40C4-ZR+ and D6000 series, the solution features a compact 1U chassis design that saves up to 90% rack space compared to traditional setups, enabling higher device density and easier deployment in space-constrained environments. The D5110-M40C4-ZR+ integrates VMUX, DEMUX, VOA, EDFA, DCM, OTDR, and OCM into one unit, replacing multiple separate devices to simplify network topology and reduce hardware investment and maintenance complexity.

Automated, Zero-Touch Configuration for Rapid Deployment

The D5110-M40C4-ZR+ supports automated optical fiber distance measurement (OTDR) and real-time auto-tuning, simplifying deployment processes and minimizing human error. With plug-and-play and zero-touch provisioning, even non-expert staff can install equipment and add new connections within minutes, significantly shortening network rollout times.

AmpCon-T Intelligent Management to Enhance O&M Efficiency

Paired with the AmpCon-T management platform, the solution offers a user-friendly visual interface for real-time monitoring of fiber and optical layer performance. It supports centralized multi-device management, multidimensional performance analysis, and rapid fault localization, enabling efficient network operations, reducing maintenance costs, and improving network stability and service continuity.
