DOCSIS resource

(No comments)

Bloomer Telephone is among the early service providers deploying the Calix 700G ONTs. According to Jim Smart, general manager with the Wisconsin-based IOC, “We face an entrenched cable competitor with a strong broadband product offering. Deploying a fiber-based outside plant that requires no powering and delivers 2.5 Gbps of IP-based bandwidth gives us a low-cost, high-capacity foundation that will allow us to significantly surpass this competitor.”

Calix announces the general availability of the 700G gigabit passive optical network optical network terminals. This expansion to the Calix 700-Series family of ITU G.984-compliant 2.5 Gbps GPON ONTs adds Gigabit Ethernet subscriber-side interfaces, enabling telcos to trump cable operators in terms of the bandwidth they can deliver to their customers. The 700G ONTs allow telcos to offer peak downstream rates of up to one thousand megabits per second, compared to 160 megabits per second for the as-yet-undeployed DOCSIS 3.0. Measured in terms of average or sustained bandwidth—a much more relevant comparison—telcos can deliver up to 80 megabits per second per subscriber in typical configurations versus a pedestrian 640 kilobits per second for DOCSIS 3.0-enabled cable operators using 250-home nodes. This represents an enormous 122-to-1 downstream bandwidth advantage for telcos with a similar differential in terms of increasingly important upstream bandwidth.
