Recommended 1Gb SFP for ~115km?

[Vinny_Abello at dell.com (Abello, Vinny)]

Hello,

 

Any pointers on real world experience on this topic would greatly be
appreciated. What are people using successfully out there as far as third
party SFP's go to hit a distance of approximately 115km? This would be for a
Catalyst 6506. Cisco's solution was a much more costly EDFA solution, but I
see plenty of vendors that make SFP's for Gigabit Ethernet that range from
115km to 150km and more. I know these are not supported by Cisco and TAC
won't troubleshoot if they are in the switch. I'm willing to work around
that should I need TAC assistance on the switch. What works well for a
single wavelength solution at this distance without having to switch to
DWDM? This circuit will have duplex fibers.

 

Thanks!
