What is the cheapest model of OTDR can measure the distance to the cliff?

Please tell me the model of the reflectometer, which you will find breaks in the fiber and the distance to them. Medium: single-mode/single-mode, working distance not more than 1-2km, the device is of one piece (without the host module), the price within 50t.R
Want to have a device for the hot test. Came to the site - no signal, pulled out a camera, shot, saw is there any breakages optics.

for single - mode "CB Bond quantum" - 53 860 RUB: fibertop.ru/tovar/56811
for couture "TOPAZ-7103-AR" - 58 800 roubles http://www.skomplekt.com/tovar/1/1/6161484216/
And combined devices are very expensive. For example, FOD-7005-035 - 630 600 RUB They are not wanted.
In your case it is likely enough OTDR for single-mode + red light.
Red light, what is that?
As I understand it, it is used to visually locate breaks?
devices for single-mode with megamode work? - arden61 commented on September 26th 19 at 11:56
I will not copy here the article. Read, there all is very simple "Visualizer damage or laser pointer – what's the difference?": fibertop.ru/lazernaya_ukazka_ili_vizualizator_povr... - Maggie22 commented on September 26th 19 at 11:59
it was pretty simple, thank you.
And about time domain reflectometer - at your first link, for example. As I understand it, this device will be able to show me the cliffs as mm and sm, when you connect with one of the parties, without the host module? - arden61 commented on September 26th 19 at 12:02
fibertop.ru/tovar/56811 - only sm
fibertop.ru/tovar/2/1/27 - only sm
If you need a MM, I recommend to pay attention on the ss-7101-AR or ss-7104-AR or ss-7311-AR fibertop.ru/tovar/2/1/32
If you want to simultaneously SM and MM, it is cheap unfortunately will not work. You need to use or two simple time domain reflectometer, as described above, or more complex, such as FOD-7005-035 fibertop.ru/tovar/60701 - Maggie22 commented on September 26th 19 at 12:05
