no convencen algunas opciones
Segun las especificaciones decia que podia medir potencia optica hasta 25 dbm pero no pasa de 15 dbm, hay que ponerlo en 850nm para que mida mas, no sirve para medir a mas de 15dbm en 1550 o 1310, y despues de 15kms el otdr no es tan confiable.

Hands down the best network testing tool I’ve ever owned
Hands down the best network testing tool I’ve ever owned. This unit replaced five separate testers I was using before, including a Fluke setup that cost me over $3,000. The feature set is extensive, with OTDR, VFL, optical power meter, light source, event mapping, and even RJ45 cable testing built into a single device. The touchscreen is responsive, the interface is intuitive, and navigating between functions is straightforward. Build quality feels professional and durable, and it performs reliably in real-world testing scenarios. For anyone working regularly with fiber or network infrastructure, this tool offers excellent capability and value in one package.

This is not the OTDR you’re looking for
Bought this is October 2025. Today is March 10th, 2026. I opened the box for the first time two days ago I plugged in the unit and 24 hours later the battery light started blinking. Battery is dead. There is no support to contact for this issue. The troubleshooting steps provided did not help me at all. I would buy a quality product that has support here in the United States if you’re gonna spend this kind of money. Save your money, buy elsewhere Update Reseller reached out to me and offered a full refund. I accepted. I’ll change this from a 1 star to a 3 star and when the refund comes back to me I’ll change it to a 5 star and buy another unit. Everyone deserves a 2nd chance.
