1310nm SFP+ module for 6100?
-
I had an installation w. 850m 65my cable (Ooold cable), where we decided to use SM SFP's because it was "Out of spec/length" for MM.
SM were still "Out of spec... 65my" but worked excellent for years.And had a colleague (in '04) that used Cisco ZX'es ($4000/pcs) in a test setup with 10m LC/LC 9my cable ... wo. "optical dampening" in the RX ends.
He blew RX in both ends ... The Boss was NOT happy ....../Bingo

My guess: this was not related to the cable, but to the TX power of the sending device.
And furthermore, using an SFP with mulitmode and connect a singlemode cable results in funny outcomes.
I have had this seen once in a customer installation, when customer complains that his connections are not stable.
Looking up in DC I saw that they connected SMF cables to MMF devices. No wonder, why connection was not stable!
A MMF device sends the laser in different modes ( (thats why it called multimode!) into the fibre medium. A lot of modes will be lost in a SMF cable.
Vice versa, using a MMF cable with a SMF device will work in most cases.Regards

We may be getting slightly off-topic here.
Pretty sure the OP isn't going to be using $4K SFP modules or burning anything out!

final update - I've tested with both DACs (works fine) and officially supported Intel 850 optics - also works well. I'm currently using the Intel optics since they are supported.
