Notes:
1.Per Tradeoff Table 52.8, IEEE 802.3ae 2005
2.For the measurements, the device was driven with 231-1 PRBS pattern.
3.Measured with a PRBS 231-1 test pattern, @10.3125Gbps,, BER<10-12
4.The LOS Hysteresis minimizes ‘chatter’ on the output line. In principle, Hysteresis alone does not guarantee chatter-free operation.
引腳定義
The SFP+ modules are hot-pluggable. Hot pluggable refers to plugging in or unplugging a module while the host board is powered. The SFP+ host connector is a 0.8 mm pitch 20 position right angle improved connector specified by SFF-8431, or stacked connector with equivalent electrical performance. SFP+ module contacts mates with the host in the order of ground, power, followed by signal as illustrated by Figure 1 and the contact sequence order listed in Table 1.
