PRODUCT DESCRIPTION
AFL's FlowScout Downstream PON Power Meter (DPPM) is designed to automatically detect and simultaneously measure coexistent downstream PON power levels at 1490 nm GPON/EPON and either 1550 nm RF video or 1577 nm XG/XGS/10GEPON.
Intuitive interface for easy operation: The FlowScout DPPM features a large color touchscreen with a simple icon-driven user interface that displays measured power levels with color-coded pass/fail indications. Measured power levels may be automatically evaluated as pass/fail against ITU-T or user-set min/max limits. The FlowScout DPPM uses a single port to automatically detect PON and broadband wavelengths.
Wave ID for reduced test time and errors: The FlowScout DPPM includes a broadband power meter for power and insertion loss measurements. Additional wavelengths can be measured using a companion CW or Wave ID source. When a Wave ID source is used, the power measurement process automatically synchronizes to source wavelengths, reducing test time and eliminating wavelength setting errors. The broadband power meter also automatically detects and reports the presence of 270 Hz, 330 Hz, 1 kHz and 2kHz fiber-identifying tones.
Full reporting capabilities: Measured power levels, pass/fail limits and status can be stored in internal memory for download via USB. Test results may be uploaded for subsequent analysis, editing, and reports generation with FlexReports PC software.
Efficient and durable: Rugged, ergonomic, and backed by an industry-best 5-year warranty, the hand-held FlowScout DPPM power meter includes IP54 weather protection, making it ideal for many conditions. It provides 16 hours of continuous operation from its rechargeable battery and can also be used while charging from the included AC adapter. A variety of field-replaceable output adapters support multiple connector styles. Basic kits include the FlowScout Downstream PON Power Meter in a convenient soft carry case.
