Is there an SFP that I can use to create a Gigabit link over a single strand of single mode fiber optic cable over a 15 Mile Distance. I can lease dark fiber between 2 locations about 15 miles apart, but leasing 2 strands is proving to be cost prohibitive, but 1 strand only could be financially feasable. I know Cisco makes the BX SFP's that can do this, but they can only go about half the distance I need. Is there another SFP I can use for this application that will work over one strand and at this distance? Ideally I would like to just have a 2960-S Switch at each end of the link with this SFP.
Any Thoughts?
