Network adapters that support 10GBase-ER optics

I'm planning to use a Supermicro server as a low-end router, but I was blindsided by the fact that the Intel X722 card only supports SR and LR optics, but my circuits are DWDM and we only have ER and ZR optics.

​

My backup option is to connect the circuits to the switch and then from switch to router, but that will burn all 4 SFP+ interfaces on the Juniper EX3400 switch, so the internal interfaces on the router will either have to be trunked with the external interfaces or the internal interfaces are 1G only.

​

Is there a PCIe network adapter that supports ER optics (DWDM)?
