Cisco 40G BiDi optics

Working on some Data Center refresh work, looking further at the most resent Nexus platforms I noticed that Cisco have released a cleaver 40Gb QSFP that will use only a single fiber pair to transport 40Gb.  Currently only available on the Nexus 9000 but I’m sure something this useful will make its way down the product list.

Update: I have them working now on the Cisco Nexus 5696Q running 7.0 NXOS, currently only prototype setup <10 Meters but they are working well.

Used this this morning for a quick refresher on the 6509E back plane cross connect, another useful posting from Mr Greg Ferro of the Packet Pushers fame. http://etherealmind.com/cisco-supervisor-720-why-architecture-performance/
