I have a project which uses Cisco catalyst switch 2970 for two sites, connected by G.655 single mode fiber. Depending on the distance, I will be using either GLC-LH-SM or GLC-ZX-SM SFP transceiver module for my switch.
From Table 2 SFP Transceiver Module Cabling Specifications in the URLthe SMF fiber recommended for GLC-LH-SM or GLC-ZX-SM is G.652.
However, the fiber will be G.655 instead of G.652 standard.
My question is whether there will be any issue using G.655 fiber for GLC-LH-SM or GLC-ZX-SM?
If not, assuming that I cannot change the fiber to G.652, is there any solution?
Thank you very much for any pointers and advice.
