Does G.655 fiber supports 1310 nm wavelenght

fibersfp

I am using G.655 standard fiber for a project. We are using short haul SFP & long Haul SFP. Long haul (1550 nm) works fine with G.655 fiber, But Short haul SFP (1310 nm) is having some issue as link is not getting up. I am not sure whether the issue is coming because use of short haul at 1310nm.

Whether 1310nm wavelenght is support in G.655 fiber with cable cut off wavelenght?

Thanks for help in advance.

If your using Cisco switches/line modules/SFP's that support DOM from the cli do show interface transceiver detail command and it will show all of the power levels. If your hardware doesn't support DOM you will get an error message. Cisco 1310 -LH SFP don't support DOM. If out of spec it will put either a + or ++ if too hot or - if too low. Definitely have to have the correct SFP reach part or things will be unstable. On 1310 short runs on good fiber loss is very minimal. Very easy to blind the receive side of the optics.
