Calix has expanded its portfolio of VDSL2 products complementing its Ethernet Unified Access Platform (ESAP), aimed at covering some of the few remaining density options that clients might require.
The new equipment includes two new Ethernet eXtensible Architecture (EXA)-powered VDSL2 lines cards for the ESAP, featuring up to 96 VDSL2 combo ports (or 48 overlay ports and support for bonding and vectoring), two 10 gigabit Ethernet (10 GE) ports, and two ports capable of GE or 2.5 Gbps service delivery. This is a two-card slot, one rack unit (1RU), modular, chassis-based product.
Calix also introduced a new VDSL2 combo card for the Calix B-Series Ethernet Service Access Nodes (ESANs), featuring 48 VDSL combo ports with bonding support and ADSL2+ fallback, as well as four 10 GE ports for optimal uplink capacity in a 1RU card. Available for the one-, six- and 12-slot B6 chassis, the new card is targeted for existing deployments that require an increase in the bandwidth of traditional DSL technologies, as well as greenfield deployments.
Rural Telephone/Nex-Tech will be upgrading its Calix equipment to migrate to VDSL2 using that new combo card. Rural Telephone is using the Calix B6 ESAN to deliver voice, video and high-speed data services in western Kansas. The provider is deploying the new B6-256 line card to increase subscriber broadband rates in existing ADSL2+ service areas.
Leveraging the new B6-256 VDSL2 and POTS combination (combo) card, Rural Telephone/Nex-Tech will nearly quadruple broadband capacity in the last mile, while simultaneously increasing access network capacity with 10 GE, Calix explained.
