PON Power Meter with 1310/1490/1550nm, Fixed SC Adapters, Dry Batteries, and Optional VFL and OPM


SKU: N/A Category:

PON Power Meter is a testing meter for FTTx’s service and maintenance. It can measure voice, data and RF video signals over optical fiber links. The upgraded color LCD display and threshold data function that can be manually set via the instrument machine are more suitable for PON network engineering, construction and maintenance needs.


  • Color LCD screen display
  • Supports synchronous measurement and display of voice, data and video signals in a PON architecture
  • Supports measurement of 1310nm upstream burst signal and 1490/1550nm downstream signal
  • Support measurement and alarm threshold setting
  • Support 1,000 data storage
  • Supports optional VFL and OPM functions
