A worthwhile investment, I received the product and tested it on my device, all my previous worries were immediately dispelled, this SFP+ transceiver fully compatible with my dell and Brocade Vendors by configuring FSBOX.
I bought two 10G BIDI optical modules for testing, and I am very satisfied with the test results. The sales person recommended me the correct compatible and everything worked as expected. I will be buying some 20km and 40km modules next, will need more later.
We had a duplex 10G cross-connect with a provider that we were able to slit into two 10G links to double our bandwidth using these bidirectional optics.
