Is it possible using only Cisco equipment to link two sites approximately 15km apart using only one single mode fiber strand.
The older SFPs are limited to 10KM, however see the list below for longer distance.
- 10KM Single Mode Fiber - GLC-LH-SMD
- 40KM Single Mode Fiber - GLC-EX-SMD
- 70 - 100KM Single Mode Fiber - GLC-ZX-SMD
