Cisco CPAK-100G-LR4 Module : 100Gbps Long-Range , Low Power , DDM Support For Data Centers

The Cisco CPAK-100G-LR4 is a high-performance 100G optical transceiver module designed for long-range data center interconnects (DCI), enterprise networks, and service provider backbones. Built with Cisco’s advanced optics technology, this module delivers 100Gbps speeds over single-mode fiber (SMF) with a 10km reach, making it ideal for high-bandwidth applications like cloud computing, 5G infrastructure, and high-performance computing (HPC).

Key Features & Benefits

✔ 100Gbps Long-Range (LR4) Connectivity – Uses 4x25Gbps CWDM wavelengths (1295/1300/1305/1310nm) for efficient 10km transmission over single-mode fiber.
✔ Low Power Consumption – Energy-efficient CPAK form factor reduces operational costs compared to older 100G modules.
✔ Digital Diagnostics Monitoring (DDM/DOM) – Real-time monitoring of temperature, voltage, and optical power for proactive network management.
✔ Cisco Ecosystem Compatibility – Works seamlessly with Nexus 9000, ASR 9000, and CRS routers, ensuring plug-and-play deployment.
✔ High Reliability – Industrial-grade components with high MTBF (Mean Time Between Failures) for mission-critical networks.
