I have a Cisco Switch ME-3600X-24FS-M (for the main site) and I would like to connect it, trough a fiber optic single strand fiber link (20 Kms, more on less), with a cheaper transceiver (on the client side), that transceiver works TX1550RX1310.
My questions:
1.- Do you have a module 100% compatible with our ME-3600X-24FS-M switch?
2.- That module can work with any transceiver BiDi 1550nm-TX/1310nm-RX?
3.- Can you offer a warranty for your modules? please explain that.
Please feel free to offer another SFP option, capable to work as we need.
I am wating for your answer anxiously.
