do, with current-generation chip-production technology. 10Ghz optics are old-school lasers, several orders of magnitude larger, much more power-hungry, delicate, and in all likelyhood, hand-crafted with low yields. They really are that expensive. Just check out the price on 10G transponders (eg DWDM equipment) if you don't believe that's the case...
Then why can I purchase 10km 10GE Xenpaks directly from the manufacturer for under $2000?
On the other hand, it'd be nice to see a copper 10GBIC, even if its max cable length were a few metres. ;-)
There is one. It's called CX4 and has a reach of 15 meters. Cisco sold it for $600 list price at first but it has now disappeared from the price list. I don't know why. http://www.cisco.com/en/US/products/hw/modules/ps4835/products_data_sheet091... -- Mikael Abrahamsson email: swmike@swm.pp.se
