Calix Launches High-Capacity Fiber Platform for the All-Video World

LAS VEGAS, NV ? Building on the success of the modular Ethernet platform it introduced nearly a year ago, Calix has expanded its portfolio with the E7-20 Ethernet Service Access Platform (ESAP), a very-high-capacity, low-latency, fiber access concentrator designed for an all-video world. The E7-20 is slated to trial in access networks in the first part of 2011 and will be widely available by mid-year.

“We fundamentally believe that the access network of the future will be dominated by bandwidth-intensive, unicast video traffic, and that the ideal medium for carrying this traffic is fiber,” says Kevin Pope, senior vice president of product development at Calix.

Architected to meet the needs of the next-generation, videocentric Internet, the E7-20 is a 2 Tbps access concentrator that can deliver hundreds, even thousands, of Mbps of video-rich content to every residential or business subscriber. Initially supporting GPON, active Ethernet and point-to-point gigabit Ethernet services on the subscriber side and multiple 10 gigabit Ethernet transport services on the network side, the E7-20 can deliver 100 Gbps to each of its 20 universal line card slots. Such emerging technologies as 10GPON, 10 Gbps Ethernet 10GE aggregation and 100 Gbps Ethernet uplinks will also be supported as they come on line.

Challenges of an All-Fiber World
The E7-20, which is meant to be deployed in a provider's central office, is focused on Ethernet-based fiber access services for high-density and high-capacity environments. It addresses the physical management challenges of high volumes of fiber terminations. Marketing director Geoff Burke explains, "It's accessible, organized, easy to provision and easy to install." (The original member of the E7 family, the E7-2 modular chassis, is designed for deployment in remote or less-dense locations.)

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. With centralized switching controllers, the E7-20 was designed to deliver fully redundant, carrier-grade performance, with full support for standards-based Ethernet ring protection switching (ERPS) and rapid spanning tree protocol (RSTP), as well as 10GE uplinks and link aggregation.

Sealed Ethernet Access Node
Calix also introduced a second new device, the the E3-48 sealed Ethernet Service Access Node (ESAN), expanding its E3 family of sealed ESANs with a powerful new option. The E3-48 provides new options for offering high-bandwidth VDSL2 services at a remote node. The environmentally hardened and sealed E3-48 combines a low-profile, compact form factor with a variety of mounting and powering options. Fiber-fed with multiple 10 GigE feeds capable of connecting to any Ethernet switch in ring, point-to-point, and daisy-chained topologies, the E3-48 ESAN can support the increasingly bandwidth-intensive services required in an all-video world. It is optimized for communications service providers pulling fiber deeper into their networks to offer broadband speeds above 100 Mbps in areas with viable copper loops.

The E3-48, the second member of the E3 family to be introduced, is designed for deployment of advanced VDSL2 copper services in low-density and remote areas. It is a sealed delivery vehicle that supports AC and -48VDC powering and can be easily installed on poles, on walls, in low-profile “dog house” enclosures, or even in the basements of multiple-dwelling units (MDUs). The E3-48 is fiber-fed, supporting up to two standards-based 10GE/1GE uplinks and four GE/2.5GE uplinks and preparing the access network edge for the high-capacity realities of bandwidth-intensive services like video.

With each unit supporting up to 48 VDSL2 subscribers, the E3-48 is designed as a right-sized access solution for rapid suburban and urban deployments, capable of being deployed on a pay-as-you-grow basis.
