## 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
