10G Tunable Optical Module Test Report

10G optical modules, including SFP+ and XFP transceivers, have been tested for high-performance transmission, link reliability, and diagnostic monitoring, confirming compliance with 10G Ethernet standards.

Key Performance Testing

Transmission and Link Performance: 10G optical modules such as the SFP+-LR-10G and XFP-10G-1550NM-80KM-SM were tested for Ethernet transmission over single-mode fiber (SMF). The SFP+-LR-10G supports up to 10km, while the XFP module supports up to 80km at 10G rates, maintaining stable connectivity and low error rates under laboratory conditions (Moduletek, Huawei) . Optical Power and Signal Integrity: Modules were evaluated for TX output power and RX input sensitivity, ensuring optical signals remain within the standard thresholds. Tests confirmed that output power relative to 1mW and received power levels meet specifications, with no transmitter faults or loss-of-signal alarms observed . Digital Diagnostic Monitoring (DOM): DOM readings were verified for all modules, including temperature, voltage, bias current, and optical power. All values were within acceptable ranges, and no alarms were triggered, indicating reliable real-time monitoring capabilities .

On-Device Identification and Compatibility

Modules were connected to switches such as Cisco C9500-24Y4C and Quidway S9303. The devices successfully recognized the transceiver type, vendor, model number, wavelength, and transmission distance. This confirms plug-and-play compatibility and accurate reporting of module information .

Environmental and Operational Testing

Temperature Range: Modules were tested across commercial operating temperatures (0~70℃) and under elevated conditions (up to 45℃). Performance indicators, including optical output and signal integrity, remained stable, demonstrating suitability for standard network environments . Voltage and Current Monitoring: Supply voltage and TX bias current were measured to ensure electrical stability. All readings were within manufacturer specifications, confirming safe and reliable operation .

Test Procedure Summary

1. Insert the module into the corresponding switch port.
2. Connect TX-RX ends with optical patch cords or loopback devices.
3. Verify connectivity, port status, and link rate.
4. Read module information from both switch and NIC sides.
5. Record DOM data, optical power, and temperature readings.
6. Compare results against datasheet specifications to confirm compliance .

Conclusion

The 10G optical modules tested, including SFP+ and XFP variants, demonstrate high-performance transmission, reliable link establishment, accurate DOM monitoring, and compatibility with standard network switches. These results confirm that the modules meet 10G Ethernet specifications and are suitable for deployment in enterprise and carrier-grade networks .
