40GBASE-CR4也叫QSFP- 40G - CR4,它与前面提到的三个40G模块有很大不同,是一种两端带QSFP+连接器的预端接铜线。40GBASE- SR4/LR4/CSR4是光模块,但40GBASE- CR4也被称为40G QSFP+直连线缆(DAC)。受铜线性能的限制,无源40G QSFP+ DAC的传输距离只能达到7m,有源40G QSFP+ DAC的传输距离只能达到10m。 如...
40GBASE-CSR4，即QSFP-40G-CSR4，是40GBASE-SR4的扩展版，采用MTP/MPO接口，搭配OM3/OM4光纤时传输距离可达300m/400m，符合IEEE 802.3ba标准。40GBASE-CR4，也称为QSFP-40G-CR4，是一种两端带QSFP+连接器的预端接铜线，适用于短距离40G以太网传输，无源DAC传输距离不超过7m，有源DAC不超过10m。
