10Gig MM fiber for 1900 ft

[peterson.m]

Is it possible to do 10Gig multimode fiber over 1900ft?  If yes, what type of transmitters would be required for that distance?

Thanks

MM won't work SM will.  What kind of fibre connectors do you want?  SC or LC?

If LC, you will need SFP-10G-LR.

IF SC, then you need to specify the appliance at both ends because you may need X2 or XENPAK.

How much over 1900ft.?

Some vendors claim 600m on their OM4.

Additionally the reach, such as typical OM4 550m, is supposed to be a "guaranteed".  I.e. somewhat further might be possible.

Cisco claims up to 400m on their SR optics on OM4.

The following BICSI discussion shows the challenges of trying to push the limits of MMF (or anything else).

Networking vendors need to be able to confortably sell solutions that are widely deployable. That is the reason they typically follow the standards for network reach. Can you go further than the standards... usually so, but doing so also opens your network to future interoperability and reliability issues when equipment needs to be repaired/replaced and the new modules don't have the same performance of the deployed modules.

Install a network that is compliant to the standards and feel comfortable it will perform and get the vendor's support in the future.
