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

Compact TPN-35 fiber power meter and OTDR tester for PON and general fiber networks, equipped with an SC/UPC interface. Measurement range: -40dBm to +16dBm, covering optical bands 1260-1360nm, 1480-1500nm and 1539-1565nm (supports standard service wavelengths 1310 / 1490 / 1550nm). Sensor and accuracy: high-performance InGaAS detector with excellent linearity — ±0.2dB at 1550nm and -40dBm — to ensure precise, repeatable readings. Data management: built-in storage for up to 900 measurement groups, plus PC connectivity for setting thresholds and adjusting calibration wavelengths. Power and environment: operates on three AA batteries (package not included) and functions reliably in the temperature range -10~+50°C with relative humidity 0%-95%RH. Portable and field-ready design for use in both onsite and laboratory testing.
