标题: 4 x 10 G和40G在成本上有什么区别？ [打印本页] 作者: wzt10gtek 时间: 2012-10-31 10:07 标题: 4 x 10 G和40G在成本上有什么区别？ • Not the same if 40Gbase-SR4 is defined to go 100 meters while 10GBase-SR must traverse 300 m
– Estimates are 10-50% less cost at 100 meters Cost isn’t everything. Users will buy 40GE over 4x10GE because of:
• Ease of Management – it’s one port versus four
• Port Density – the QSFP is a factor of 3 denser than the 4 SFP+
• Cable Management – One ribbon is easier to manage than 4 duplex patchcords
