Redwave Optics Juniper EX-SFP-10GE-SR 100% Compatible 10GBASE-SR SFP+

• SFP+ transceiver module
• 10GBase-SR
• LC multi-mode
• for Juniper EX 3200; 4200

above is the gbics we have, our data carrier says they will give us single mode LC fiber.

Can I use these gbics or do I need to order single mode.

Thanks

No, you cannot connect multimode optics to single mode optics they are not compatible.  The LC is just the physical connector type and size.

You will also need to coordinate matching wavelength of the optics.

10GBase-SR could be used with OM1, OM2 or OM3 MM-fiber ONLY.

Spuluka,

Can you suggest a gbic for this, the ones I show are over $700

my manager thinks that is too much, not right.

Yes, single mode optics are much more expensive than multi-mode optics.

But it also looks like the CDW link is for an XFP form factor when your data above shows you have an SFP device.  The XFP is a larger size and not able to plug into the SFP slots.

I've had good experiences with Champion optics.  But bear in mind that if you have optics related issues you will not be able to have a JTAC case if you don't have Juniper branded optics.
