Introduction
Analysis of the core content of the standard
This standard establishes a complete GPON equipment energy efficiency evaluation system, and classifies the energy efficiency of OLT and ONU equipment through the dual indicators of power consumption limit value and energy efficiency index. The technological evolution is reflected in:
- The multi-power consumption state model of GPON equipment is defined for the first time
- Innovative port normalization energy efficiency algorithm is proposed
- Introduction of mixed service flow test scenarios
Equipment energy efficiency indicator system
| Equipment type | Core indicator | Test status | Energy efficiency grading threshold |
|---|---|---|---|
| OLT | Average power consumption of PON port ≤7.7W | Full power consumption state | Level 1: EEI<0.7 |
| SFU/HGU | Power consumption of the whole machine ≤4.0W | S1/S2/S4 mixed | Level 2:0.7≤EEI<0.85 |
| MDU | DSL port classification limit | Service status weighting | Level 3:0.85≤EEI≤1.0 |
Key test methods
OLT test points
- Use 64/512/1518 bytes mixed frames (4:2:4 ratio)
- Load test on each service card
- AC power supply allows 10% power consumption increase
ONU status definition
| Interface type | Full power state | Low power state |
|---|---|---|
| GPON port | O5 state service transmission | O5 state no service |
| WLAN | 50mW transmit power | Beacon mode only |
Typical application cases
Energy efficiency calculation of card-type MDU
Configuration of a certain model of MDU:
- 16-port VDSL2 board (supports Vectoring)
- Port opening rate 60%
- Actual power consumption 42W
Calculation process:
PLMT = 6 + (0.2×2.0 + 0.8×0.7)×0.6×16 + 0.4×0.4×16 = 23.68W EEI = 42/23.68 = 1.77 → Energy efficiency does not meet the standard
Implementation Suggestions
Application of Energy-Saving Technology
| Technology Type | Amount of Energy Saving | Applicable Scenarios |
|---|---|---|
| Fast Sleep | 30-50% | Residential ONU Nighttime |
| Dynamic power adjustment | 15-25% | OLT board load fluctuation |
Testing precautions
- DSL testing must strictly follow the loop model in Table 11/12
- WLAN testing requires controlling the terminal distance to 1-5 meters
- Voice interface is calibrated according to 25mA feed current
