Unified Solutions for IP Over DWDM

With the rise of AI technologies, the dynamics of network traffic within data centers are evolving. A surge in east-west network traffic is driving unprecedented growth in bandwidth demand for data center interconnects (DCIs). In parallel, telecom service providers face mounting pressure to upgrade their metro networks to accommodate higher speeds and greater bandwidth capacity in point-to-point or multipoint to multipoint scenarios. Amid these shifts, operators are seeking cost-effective, efficient, and straightforward solutions. This is where Internet Protocol over Dense Wavelength Division Multiplexing (IP over DWDM or IPoDWDM) come into play – a transformative technology set to redefine network architecture.

What is IP over DWDM?

IP over DWDM seamlessly integrates IP routers or switches in data centers into Optical Transport Networks (OTN) using pluggable DWDM transceiver modules. This integration eliminates the need for intermediary transponders and grey interfaces between routers and DWDM line systems, paving the way for simplified and streamlined networks. Leveraging advanced pluggable transceivers like 400G ZR/ZR+ or 100G ZR digital coherent optics (DCO), IP over DWDM delivers robust performance across diverse applications.

Benefits

• Cost Savings: By removing transponders and additional OTN equipment, IPoDWDM reduces power consumption, footprint, and capital expenditures (CapEx).
• Scalability: Designed to adapt to growing network demands, IP over DWDM ensures future-proof deployments.
• Network Optimization: Simplified architectures reduce points of failure, enhancing reliability and operational efficiency.

OPTICAL TRANSCEIVERS

To further demonstrate the advantages of IP over DWDM technology, we conducted an in-depth case study using Approved Networks' 400G ZR+ 0dBm and passive DWDM mux/demux. In this study, we compared the costs associated with implementing IP over DWDM versus the traditional OTN approach. The 400G ZR+ 0dBm enabled IP over DWDM use case demonstrates the potential of unified solutions to revolutionize metro networks and DCIs. Using 400G ZR+ transceivers and passive mux/demux, this configuration achieves:

• Increased Bandwidth: Up to 3.2 Tb/s over 80 km unamplified using just two single-mode fibers.
• Cost Savings: Customers can save up to 75% compared to leading OEM muxponder solutions.
• Simplified Network Configuration: SBy eliminating the transport layer, operators can streamline operations and reduce complexity.

As the digital landscape continues to evolve, the demand for fast, dependable, and cost-effective data transmission is becoming more critical.
