Review: Easy to set up - plug and play - Simple to install. . Works as expected
Review: Worked fine - Worked fine from the start no problem Better as no copper cables for going outside and then back in Fibre easyer to run, some cables more durable and more reliable as no interfearence and less likely to break after movement as more durable core than copper Jus ashame that they are not universal so have to get apecial ones for sifferent companys devices True gigabit instead of coppers gigabit as copper looses some advertised speed in my experience

## Questions & Answers

**Q: What cable to use with this SFP?**
A: Hi,this module accepts fibre cable with LC connection, it then depends upon what its connecting to as you can get a variety of connections . For maximum potential it should be multimode duplex cable. But if its connecting to a single mode unit then you can downgrade the cable , though it will fit to the lowest mode fitted.Hope this helps, apologies for the delay in getting back to you.RegardsNM
