This is not a switch, it's a fan-out device for one-to-many and many-to-one communications. It does not do L2 forwarding, MAC address learning, security, multicast, QoS, or congestion control. It's only use is for a SINGLE host to exchange low-latency lightweight messages with a bunch of other hosts. 10GE is used for its low latency properties only. In fact, if you actually tried to send any sort of high traffic volume through this mux, it would fall on its face.

Before you do, ask how much bandwidth Cablevision provisions to serve each neighborhood. A 100 Mbps last-mile connection isn't worth didly-squat if the CMTS head-end only has a 155 Mbps uplink. Even a gig uplink is only enough for about 80 customers, given typical 8:1 oversubscription. Many ISP's don't mind 100:1 oversubscription or worse!
