Measurement Capabilities and Features
- In‑service PON testing: Filtered 1650 nm and PON power meter enable single‑port, in‑service checks on live networks without disrupting customer traffic.
- A‑range performance: Short event dead zone and short‑pulse capability make the unit effective at resolving closely spaced connectors, splices and drop‑fiber events.
- Smart acquisition: Automated acquisition modes reduce manual setup; combines short and long pulse strategies to capture near‑end events and longer loss profiles.
- Bidirectional and loss analysis: Supports bidirectional comparison workflows for improved loss accuracy where required.
- Onboard analysis and reporting: Generates standardized test reports and pass/fail results for acceptance documentation.
Connectivity and Software
- Data export: PDF report generation and exportable trace files for acceptance and archival.
- Remote access: USB and optional wireless connectivity for remote control, cloud sync and firmware updates.
- Guided workflows: Preset test profiles and icon‑based results simplify operation for technicians with varying experience levels.
Practical Considerations for Buyers and Field Use
- Calibration: Confirm recent calibration for contractual acceptance testing.
- Accessories: Use a short launch/receive cable, appropriate connector adapters and dust caps for accurate near‑end measurements.
- Compatibility: Verify the exact model variant (connector type, filtered option) and host firmware compatibility if integrating into existing test procedures.
- Condition checks: Inspect optical endfaces and verify power meter zeroing and light source stability before critical tests.
Typical Use Cases
- FTTx commissioning and acceptance — splitter loss verification and optical budget checks.
- PON in‑service verification — single‑port checks on live networks using filtered 1650 nm.
- Access network troubleshooting — locate and characterize faults on short distribution and drop fibers.
