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

TPN-35 is a multi-function fiber test instrument combining an optical power meter with OTDR capabilities for PON environments. It measures optical power across the PON wavelengths 1310, 1490 and 1550nm and accepts SC UPC connections, with a measurement range of -70~+10dBm. Built for accuracy, the TPN-35 produces consistent, reliable power and loss readings so technicians can confidently assess link quality and signal strength. Its precise measurements help verify performance and pinpoint issues during commissioning and routine checks. The unit’s compact, lightweight design makes it convenient for both field work and lab use — easy to carry between sites without adding bulk. Telecom engineers and fiber technicians will find it indispensable for installation verification, troubleshooting, maintenance and equipment servicing, helping reduce downtime and keep networks running smoothly.
