I want connect SFP module to the XC2VP7 (use RocketIO in custom mode in

2488 Mbps, ie STM-4). But I anywhere find example of circuit. Are they
connected in AC-coupled mode only or I can connect them in DC-coupled?
In data sheet for SFP-modules I that the internal capacitors 0,1 ľF
are connected sequental RX and TX data lines. Were I can see examles or

read about it? And about pull up/down and terminatir resistors...

Thank
