Long Haul SFPs. EZX type?

[TSully10953]

Hi all, 

New to forum. I have a question on SFPs. I'm looking for 1G SFPs that will go approx 110km between Cisco units.

My understanding is that this is beyond the capability of ZX SFPs but i have seen there are EZX SFPs that go to 120km.

Could anyone advise are there any limitations using these? I dont see any mention of them in Cisco's Product line.

Appreciate any help.

You can use a pair of 1Gbps CWDM SFPs directly into fiber (no mux/demux filter) to reach the distance you are requesting.

Thanks for the reply. 

Just looking through the spec you shared, do i need additional units with those CWDM SFPs?
