very nice. thanks

works good. thanks


Works perfectly, exactly what I needed

This module worked perfectly for a 100 meter fiber.


Pop them in and forget about them.

My standard go to between Mikrotik Routers and Ubiquiti Edge Switches. Even tolerant of "accidental hot swapping". Pricing tends to fluctuate a bit thou.


Never have any issues with Mikrotik

Great product, very reliable.



Good product
