Core parameter analysis
Key technical indicators of optical interface
Typical parameters of SFP+ modules in 10GBASE-LR applications:
- Center wavelength: 1260-1360nm
- Transmit optical power: -8.2~+0.5dBm
- Receive sensitivity: ≤-12.6dBm
- Extinction ratio: ≥3.5dB
New 12G CPRI features
Parameters OL-119 requirements Rate 12.16512Gbit/s Transmission distance 10km Power budget 9.4dB
Implementation suggestions
Selection guide
- Rate matching: OL-119 12G module is recommended for 5G fronthaul
- Power consumption control: Level II (≤1.5W) is suitable for dense deployment scenarios
- Compatibility verification: It is necessary to test whether the SFI interface SDD11 parameters meet the requirements of the new version of Appendix B
Test points
According to the requirements of Chapter 6, focus on verifying:
- OMA stress receiving sensitivity (new 12G test item)
- Hot plug transient current in high power mode
- RF immunity under 3V/m field strength (GB/T 17626.3)
