Cannot connect Alcatel-Lucent I-W240-A to Nighthawk D7000 router

[cano136]

I cannot connect the router to my ISP modem becuase this particular model does not use an ethernet cable. It uses an optical cable. I am trying to connect a Nighthawk AC1900 D7000 router to an Alcatel-Lucent I-W240-A optical router.

You will have to use ethernet in order to connect to the D7000 WAN port.
