Is it necessary to add the AC coupling capacitor between DS100DF410 and SFP Plus module?

Hi TI experts,

In my design, I use one DS100DF410 to transfer XFI interface of 66AK2H14 to SFP Plus module.

There is one question that the DS100DF410 datasheet shows me that the TX and RX channels must be AC coupiling, however, the SFP Plus module has AC coupling capacitors  in its both TX and RX channels such as this module http://www.avagotech.com/products/fiber-optics/optical-transceivers/sfp-plus/afbr-709dmz.

So can I delete the AC coupling capacitors in the host board?
