What is an XGPON Power Meter?

In simple terms, an XGPON power meter is a testing instrument specifically designed for the installation, maintenance, and troubleshooting of high-speed fiber optic networks like XGPON. It not only measures the strength of optical signals but also accurately distinguishes between multiple different wavelengths transmitted simultaneously within the network, making it a crucial tool for ensuring the quality of 10G-PON networks.

What are XGPON Power Meter's core functions and features?

1. Multi-wavelength synchronous measurement: This is its most crucial function. In an XG(S)-PON network, uplink and downlink data and video signals are transmitted through the same optical fiber using light of different wavelengths. The XGPON power meter can simultaneously measure all these key wavelengths:

• Downlink signals: 1577nm (XGS-PON data), 1490nm (GPON data), 1550nm (RF video signal).
  

• Uplink signals: 1270nm (XGS-PON burst mode), 1310nm (GPON burst mode).
  

2. Penetrating-through mode: In this mode, the XGPON Power Meter does not interrupt normal network communication during testing. The OLT (Optical Line Terminal) and ONT (Optical Network Terminal) maintain a continuous connection, facilitating online testing.

3. Burst Mode Measurement: Accurately captures and measures discontinuous bursts of uplink optical signals emitted from user-end equipment (ONU/ONT).

4. Pass/Fail Analysis: Users can preset acceptable thresholds for optical power. After measurement, the instrument visually displays whether the result meets the standard using color or icons, greatly simplifying the judgment process.

5. Data Logging and Connection: Most models support saving thousands of test results and can export data via USB or Type-C interface for report generation or further analysis.

What are the main applications of 10G EPON XGPON Power Meter?

XGPON power meters are mainly used in various stages of fiber optic networks:

1. Network Installation and Activation: Used to verify whether the received optical power is within the normal range required by the equipment when installing new users or opening new sites.

2. Network Maintenance and Troubleshooting: When users report network faults, technicians use it to quickly locate whether the problem is due to low optical power, wavelength interference, or other signal quality issues.

3. Network upgrade verification: When upgrading from a traditional GPON/EPON network to a 10G-PON network, confirm whether the old and new wavelengths can coexist without interfering with each other.

How to Choose a Suitable XGPON Power Meter? 

There are many brands of XGPON power meters on the market. You can choose based on the following points:

1. Compatibility: Ensure the device explicitly supports XG-PON, XGS-PON, and 10G-EPON standards, and ideally, it should also be compatible with traditional GPON/EPON networks to adapt to mixed environments.

2. Key Performance Parameters: Pay attention to measurement accuracy (typically ±0.5dB), measurement range (e.g., -50 to +20dBm), and insertion loss (lower is better, typically ≤1.5dB).

3. Ease of Use and Durability: Choose a model with a clear screen and simple operating logic. For outdoor use, a robust chassis and some dust and water resistance (e.g., IP54 rating) are important.

4. Budget and brand: Well-known brands such as VIAVI, EXFO offer high-performance products, while some China brands offer cost-effective options with excellent working performance too.
