TL537 Optical Power Meter — Fiber Light Meter -70~+10 dBm with 6 Calibrated Wavelengths, FC/SC/ST Universal Interface, 68g Lightweight Fiber Optic Tester for FTTH Splicing & Maintenance

I picked this up when my other opm quit working on me. I didn't want to spend a ton of money on one, and honestly, its been pretty decent for the price. It is super compact and weighs almost nothing so it's easy to shove in my pocket and go. It has been accurate so far. I don't use it for every wavelength, obviously but 1550 has been spot on. I've had it for a few months now and have only charged it twice. The battery life is great. It does feel a little cheaply made, but for the price, that is to be expected. If you need a reliable backup meter or one to carry around with you and not have to worry about losing or breaking it, this is it. Highly recommend. I do intend on buying a better one at some point and using this for a backup, but you can't go wrong.

Their is nothing that I don't like. Very easy to use, seems accurate enough for field work and can easily slip in a pocket or use the case that comes with it.

The unit measures 1.4dBm too long, but serves it's purpose as a very portable measuring device.

This little meter is just -1 off than my $$$ big Optimeter... when I'm climbing poles and need to hook up fiber drops, it's so much easier bringing this small item than the very large and pain in the @#$%& Optimeter. So when I know I got light, I'm good to the slacknid at customer prem then the FJ. Definitely easier to use. This gives me ready within 5 seconds turn it on. While the large OptiMeter takes about 3-5 minutes for a reading. So there is a -1 difference between the handheld and the large . It's negligible. Overall happy with this product. Using it about 4 months now. ****????"""""""""???????"""""""""""""""" Note: Only downside.... wish they provided a carrying pouch for your belt... but you can't have it all

As a fiber installer I’m required to test light. Instead of carrying my meter I check the light with this and make sure the installation can happen. Screen is easy to read and has a backlight for dark areas. 2 triple A batteries are required for operation. The shape is a bit odd, thin pear like but fits in the hand comfortably. Cheap housing but expected for the price you pay. Accuracy is a bit off, so if something precise is required for you. Expect to pay more. Be sure you’re measuring the proper wavelength.

I really like this product. I work in with fiber optics every day and this product been one of the best investments I made. One thing that I really like about this product is the potability it’s small but still has all the things that I need.

I work with fiber in an Internet installation capacity. this meter is smaller than the one provided to me and can fit in my waist carry tool pouch and quickly test the light level. turns on quickly and turns off quickly. Be sure to set your light intensity so you get the proper reading. only have to do this once as it saves your input.

I tested this along side the company provided very expensive light meter and they are about the same maybe a decibel or two off. Would definitely recommend
