I got these two devices, it has RF IN, OUT, Rev, Fwd so it looks like a ready made reflection meter and SWR meter for RF transmitters. But I know nothing and getting problem to get information about it in the internet. If I could get some datasheet or app note, it would be nice.

look it up on google.
It is a 115 to 400 MHz directional coupler. Plenty on ebay for $50.
Being BNC connectors is probably 50 ohm.
hope this helps.
 
I agree it is a directional coupler.

The manufacturer Olektron is now part of Crane
Looking through their website, I cannot find any reference to this item. My best guess is that it is now obsolete.

If you want some insight into the working of directional couplers, have a look here:

Hi,
It looks like it's a factory made SWR meter as I uploaded a diagram below. Bi-directional couplers sounds little complicated.
