Calix has launched the E7-20 multi-terabit Ethernet Service Access Platform (ESAP), expanding its Unified Access portfolio with a high capacity, low latency, all-fiber access concentrator designed for “an all-video world.”

Architected to meet the needs of the next generation Internet where high bandwidth Internet protocol (IP) video streams proliferate and are delivered over fiber access infrastructure, the E7-20 is a two terabit per second (Tbps) access concentrator with the ability to deliver hundreds, even thousands, of megabits per second (Mbps) of high-bandwidth, video-rich content to every residential or business subscriber.

Initially supporting gigabit passive optical networking (GPON), Active Ethernet (AE), and point-to-point gigabit Ethernet (GE) services on the subscriber side and multiple 10 gigabit Ethernet (10GE) transport services on the network side, the E7-20 has the capacity to deliver 100 gigabits per second (Gbps) to each of its 20 universal line card slots. This enables the platform to support emerging technologies such as 10 gigabit passive optical networking (10G PON), 10 Gbps Ethernet (10GE) aggregation, and 100 Gbps Ethernet (100GE) uplinks.

Slated to trial in access networks in the first part of 2011 and widely available by mid-year, each E7-20 will serve up to 480 dedicated AE subscribers or 5,120 GPON subscribers – with sufficient headroom to accommodate more than 20,000 subscribers through the introduction of higher density and higher capacity line cards in the future.
