## Questions & Answers

**Q: Does this lc connector support upc or apc fiber connections.... or both?**
A: This SFP is only for UPC fiber connections.  If you have a APC fiber you need to connect it to, adapters are available to do that.

**Q: Does it support 220v ?**
A: Yes.  The adapter states input voltage 100-240VAC  You will need an adapter if you get the US plug model as mine came with a standard US adapter.

**Q: Is it compatible with a hp j9660a or a dell powerconnect 2724?**
A: I am using this with the MC220L Transceiver converter and it works great.  However you can use this in any switch that has a SFP or SFP+ port.  Both the HP and Dell you stated do have SFP ports so you are good on either.

**Q: Is this module compatible with Netgear Switch?**
A: They are pretty much interchangeable.  I put them in tp-link switches but from what I got at my local fiber optic store is that they are all the same.
