Unsure what you are looking for. If you are looking to extend service out from the Calix E7 you can try these folks. I have used their gear to push ethernet circuits over a couple of miles.

You can also try ADC Campus Pairgain modems. They can push HDSL, SDSL signal to around 12 miles over OSP Plant if I remember their specs correctly. I have used a butt ton of them and they are solid.
