• Do not touch the ends of connectors. Touching the ends can leave fingerprints and cause other
contamination.
• Clean the connectors regularly; the required frequency of cleaning depends upon the environment. In
addition, clean connectors if they are exposed to dust or accidentally touched. Both wet and dry cleaning
techniques can be effective; refer to the fiber-optic connection cleaning procedures for your site.
• Inspect routinely for dust and damage. If you suspect damage, clean and then inspect fiber ends under a
microscope to determine if damage has occurred.
If cable length is more than 5 meters, Auto Negotiation is not supported. Note
Connecting to Transceivers
The XCVU35P-3e FPGA has 56 28Gbps capable transceivers. 48 of them are directly connected the SFP
ports. The remaining 8 transceivers are connected to the Intel Atom CPU through a PCI Express (PCIe)
interface.
The following diagram shows where the transceivers used for Ethernet and PCIe are located in the FPGA.
