Review: Works great on SOTM SN10G SFP port switch. This is a 1G module. Have purchaed Finisar 1475 which is 10G bandwidth module however SOTM switch cannot support 10g.Users might want to tale note. Sound wise, clear as a whistle no issues so far as am using this TPLINK module daisy chain to another SOTM SN10G. With fibrepro 7" length LCLC os2 .You can buy the whole wide web of modules to try and narrow them down to the best sound for any audiophile given switch but I find that it is a waste of money and time.You are better off playing LPs.However for TIDAL streaming does works fine for me and have tested playing back and forth from a ripped to wave cds 44.1/16bit direct from cocktail x40 thru uab (sotm usb ultra onboard clock) and with Lenovo laptop also with Sotm txusb ultra, TIDAL, the tidal does sound slightly similar but take note though, the decay of the cymbals ended (faster)lesser last note shimmering decay effect. Softer no bite.No air surrounding the cymbals.No idea why?All psu are plixir balance elite .Amps are Belcanto ref500s to Mytek broolyn dac+ and cables kimber ks1021/ pk10 palladian /ks2036/8tc.SR fuaes amd bybees with shakti stones and shakti onlines.SR tranqua bases. Update 1 Now having bought 08 and no issues at all. Only for LC to LC fibres and OS single mode SM single mode. Do not use OM or MM multimode. Do not mix the IN and OUT of the module.Wise choice to go with same module maker/ model nbr.

## 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.
