Cisco CVR-CFP2-CPAK4 - Overview
The CFP2-to-CPAK adapter was designed to bridge Cisco’s proprietary CPAK form factor with the more widely adopted CFP2 standard. By using this adapter, customers can deploy Cisco CPAK optics in systems that only have CFP2 ports, avoiding the need to replace existing hardware.
🔧 Key Specifications
-
Form Factor:
- CFP2 mechanical housing with an internal CPAK slot
-
Function:
- Accepts a Cisco CPAK 100GBASE module
- Electrically and optically emulates a CFP2 100GBASE module
-
Supported Optics:
- Cisco CPAK 100GBASE modules (e.g., SR4, SR10, LR4, ER4L)
-
Interface:
- Front: standard CFP2 connector (to host system)
- Inserted: Cisco CPAK transceiver
-
Power Management:
- Pass-through power from CFP2 host to CPAK module
- Lower power consumption than native CFP/CFP2 optics when using CPAK modules
-
Platform Support:
- Cisco platforms with CFP2 client ports (e.g., ASR 9000, CRS, NCS series line cards)
🧩 Ideal Use Cases
-
Migration flexibility: Use CPAK optics in CFP2-based systems without replacing hardware
-
Data center interconnects: Short-reach (SR4/SR10) or long-reach (LR4/ER4L) 100G links
-
Service provider networks: Where mixed form factors exist across platforms
