TPN-35 Multi-Function Fiber Optic Power Meter & OTDR Tester (PON) — SC/UPC, 1310 / 1490 / 1550nm

The TPN-35 is a multi-function fiber optic power meter and OTDR tester built for PON applications. It covers a measurement range of -40dBm to +16dBm and supports the common telecom wavelengths 1310, 1490 and 1550nm. Optical frequency/measurement bands include 1260-1360nm, 1480-1500nm and 1539-1565nm. An advanced InGaAS sensor delivers excellent linearity with a deviation of only ±0.2dB at 1550nm and -40dBm, ensuring consistent, accurate readings. The unit stores up to 900 measurement groups internally and can be connected to a host computer for threshold configuration and calibration-wavelength adjustments. It uses SC/UPC connections and is powered by three AA batteries (pack not included). Designed for field or laboratory use, the TPN-35 operates across an environmental range of -10 to +50°C and 0%-95% RH.
