Active Cabling Specifications
are not specified by this standard, it is expected that SFP+ Active Cables operate with either linear or limiting hosts as defined in section X.2.
An example of active cable assembly with active transmitter is shown in Figure 1. The cable assembly shown has an active transmitter and active receiver. Other implementation possible are active-passive and passive-active. The cable assembly shall incorporate DC blocking capacitors with at least 4.3 V rating between any signal commissioning IC and the SFP+ edge card connector1. The DC blocking capacitor shall have high pass pole of between 20 kHz and 100 kHz. For a copper cable assembly, the drain wire is connected to VeeT and to VeeR and the cable shield directly connects the module A and cases.
