2X TM581 PON Power Meter SC Optical Fiber Tester — OLT 1310Nm/1490Nm/1550Nm

Model: TM581 PON Power Meter. Wavelength(nm): 1310±50nm/1490±15nm/1550±10mm. Designed for use on PON networks, this meter extracts a small portion of the live optical signal to perform testing throughout FTTx commissioning, maintenance and troubleshooting. It simultaneously measures optical power for voice, data and video channels and issues an alarm when readings exceed preset thresholds—making it suitable for engineering, installation and field maintenance tasks.
