Review: Great for home installs. - It does exactly what it says. I use it to get internet to a detached garage that's a steel building and wifi can't reach. I ran the fiber with the power wire about 300 feet away. It hasn't missed a beat. I wouldn't use it In a Comercial install unless it's an emergency just because it does not report any status. It's invisible on the network so you only see whatever you plugged into it.
Review: Worked great for my purposes - I live in central FL, lightning capital of the US. I got tired of lightning strikes taking out my cable modem, my router, my switch and occasionally the Ethernet on my motherboard. So I bought these and installed them as an optical isolation break between my modem and router. 3 years on they are still working and I’ve had one modem toasted - but only the modem. I am switching to fiber Ethernet into my house so these no longer serve a purpose, but I thought I’d leave a review to praise them for the last 3 years of protection

## Questions & Answers

**Q: Can this unit power over ethernet POE? or be used as rs422 serial through ethernet?**
A: Nope.  Psybridge made a product like that.

**Q: Can i use this to convert the fiber to a rj45  for my router?**
A: This converts rj45 to fiber and back again.

**Q: can you manually set to Full Duplex / speed?**
A: No

**Q: Can you recommend a 2 meter fiber patch cable will enable 1000Base transfers?**
A: Through the RJ45 gigabit cable transmission within 80 meters, can achieve gigabit rate;
1.For 2 meters of fiber transmission, the gigabit rate is directly determined by the fiber module and the fiber tran.sceiver. 
2The specification interface of the 2 meters of fiber jumper, FC-SC-LC-ST, is determined by the fiber module.
