Slots and Bandwidths - Optical Systems
The optical solutions offer a variety of configurations and bandwidths depending on customer
requirements. Each HLink-Optical is capable of transferring up to PCIe Gen.3 x8 bandwidths across
distances up to 100m. To achieve this the HLink-Optical must be installed in a x8 PCIe slot on the host
backplane and connected to the corresponding SLink-Optical card pre-installed in the PICMG 1.3 slot in
the expansion chassis using two ExCable-Optical cables.
A x4 bandwidth can also be achieved by connecting the HLink-Optical (installed in a x8 PCIe slot ) to two
separate SLink-Optical cards. If the HLink-Optical is installed in a PCIe x4 then it can only be connected to
one SLink-Optical card.

(3) All 11 slots in the VSN1100X-Optical expansion chassis are PCIe x8 lane therefore two ExCables-Optical are required. If
the requirement is for x4, only one ExCable-Optical is required, however this reduces the available bandwidth by 50% and
therefore reduces the amount of video signal that can be transferred.
