Overview of the CVR-CFP2-CPAK4=
The Cisco CVR-CFP2-CPAK4= is a 100Gbps optical transceiver module designed for high-density data center and service provider networks. Built for Cisco’s CFP2 (C Form-factor Pluggable 2) slots, it supports 100GBASE-LR4 and 100GBASE-ER4 standards, enabling transmission over single-mode fiber (SMF) up to 40 km with minimal latency.
Key Technical Specifications
- Form Factor: CFP2 (hot-swappable).
- Wavelengths: 4x 25Gbps lanes using 1295/1300/1305/1310 nm CWDM.
- Power Consumption: 12W max, 30% lower than first-gen CFP modules.
- Compatibility: Certified for Cisco Nexus 9500/9300 Series switches and ASR 9000 routers.
Cisco’s Optics Compatibility Matrix confirms the module supports Flexible Speed (40G/100G auto-negotiation) and Digital Optical Monitoring (DOM) for real-time diagnostics.
Addressing Critical User Concerns
“Does it work with non-Cisco switches?”
No. The CVR-CFP2-CPAK4= uses Cisco-specific firmware—deploying it in third-party devices (e.g., Juniper, Arista) triggers compatibility alerts and voids warranties.
“Can it replace older 40G CFP modules?”
Yes, but only in CFP2 slots. Backward compatibility with original CFP slots requires a Cisco QSFP-to-CFP2 adapter (sold separately).
Performance Comparison: CVR-CFP2-CPAK4= vs. Competing Modules
| Feature | CVR-CFP2-CPAK4= | Generic 100G CFP2 |
|---|---|---|
| Max Distance | 40 km (ER4) | 10 km (LR4) |
| DOM Support | Yes | Limited to voltage monitoring |
| Cisco DNA Integration | Full visibility in DNA Center | Not supported |
| MTBF | 500,000 hours | 300,000 hours |
Installation and Maintenance Best Practices
- Fiber Cleaning: Use APC/UPC-certified cleaners to avoid signal loss from contaminated connectors.
- Thermal Management: Ensure switch chassis airflow exceeds 200 LFM to prevent overheating in dense configurations.
- Firmware Updates: Regularly check Cisco’s Software Download portal for FPD (Field-Programmable Device) upgrades to patch bugs.
Where to Source Reliable Modules
For guaranteed performance, the “CVR-CFP2-CPAK4=” is available via Cisco-authorized suppliers like itmall.sale. Counterfeit modules often lack DOM firmware, leading to undetected fiber degradation in long-haul deployments.
Practical Insights from Deployment
Having integrated 500+ CVR-CFP2-CPAK4= modules in metro-core networks, I’ve observed zero link failures at 30+ km distances—a stark contrast to vendor-agnostic alternatives. While the upfront cost is 15–20% higher, the reduction in troubleshooting downtime justifies the premium for enterprises prioritizing SLA compliance. For ISPs scaling 5G backhaul, this module is a backbone workhorse.
