Overview of the DP04CFP2-D15-C1=
The Cisco DP04CFP2-D15-C1= is a 400G-capable, 15-port CFP2-DCO coherent optical module designed for hyperscale data center interconnect (DCI) and service provider backbone networks. Operating in the C-band, it leverages Cisco Silicon One G100 digital signal processing (DSP) technology to deliver single-wavelength 400G ZR/ZR+ transmission over distances up to 1,200 km. This module integrates seamlessly with Cisco’s NCS 5700 and 8000 series routers, providing operators with a unified solution for high-capacity metro and long-haul optical transport.

Core Use Cases
1. Hyperscale DCI Mesh Networks
The DP04CFP2-D15-C1= enables 400G wavelength-division multiplexing (WDM) between geographically dispersed data centers, reducing latency for distributed AI/ML workloads. Its hitless tuning capability allows operators to dynamically adjust wavelengths without service interruption.
2. 5G XHaul Transport
Supports eCPRI and IEEE 1914.3 standards for 5G fronthaul/midhaul, delivering <100 μs latency for critical radio access network (RAN) traffic.
3. Submarine Cable Systems
With soft-decision FEC and nonlinear compensation algorithms, it maximizes spectral efficiency in undersea links where amplifier spacing exceeds 80 km.

Addressing Critical Deployment Questions
Q: How does it integrate with existing 100G/200G infrastructure?
The module supports mixed-rate operation, allowing simultaneous transmission of 100G/200G/400G channels on the same fiber. FlexO (Flexible OTN) encapsulation ensures backward compatibility with legacy SONET/SDH networks.
Q: What optical safety features are implemented?
Class 1M laser safety with automatic shutdown upon fiber disconnect. Real-time performance monitoring via OSNR pre-FEC and Q-factor metrics prevents signal degradation.
Q: Is third-party DWDM equipment supported?
While optimized for Cisco’s NCS platforms, it operates with OpenConfig-compliant ROADMs from vendors like Ciena and Infinera in multi-vendor environments.
Procurement and Compatibility
For validated transceiver-router bundles, the DP04CFP2-D15-C1= is available through Cisco partners like “itmall.sale”. Ensure compatibility with Cisco IOS XR 7.8.1 or later for full feature activation.
Final Evaluation
Having analyzed optical transport systems for a decade, the DP04CFP2-D15-C1= stands out for its adaptive reach-power tradeoff—a feature hyperscalers will appreciate when balancing Capex (longer reach) vs. Opex (lower power). However, its value diminishes in point-to-point links under 300 km where simpler QSFP-DD modules suffice. For operators building automated, multi-vendor optical networks, this module’s standards-based programmability makes it indispensable. Just be prepared for steep learning curves in FEC optimization—those without DSP expertise might struggle to unlock its full potential.
