Calix announced the availability of standards-based broadband passive optical network (BPON) optical line terminal (OLT) line cards for its Calix C7 multiservice platform. Service providers are able to integrate support for FTTP BPON in the same Calix C7 platform that delivers ADSL2+. A fully loaded Calix C7 supports twenty dual-port, G.983-compliant cards for a total of 40 BPON OLT ports driving 1,280 ONTs in an 8-RU form factor. As many as five compact, high capacity C7s can be housed in a single seven-foot equipment rack, yielding 200 OLT ports and 6,400 ONTs per rack. Service providers can also install the new FTTP BPON line units in Calix outdoor cabinets, which range in size from 20 OLT ports / 640 ONTs to 240 OLT ports / 7,680 ONTs.
To date, over 150 North American service providers with approximately 22 million access lines have deployed more than 4,500 C7 platforms and 750,000 ports into production network infrastructure. Calix said this fully operationalized footprint represents capacity for over two million ADSL2+ subscribers or more than five million FTTP BPON subscribers.
The Calix 7 offers 200 Gbps of backplane capacity. Calix said its system also provides the transport functionality and the slot capacity for eventual migration to 10 Gigabit Ethernet trunking and services. http://www.calix.com
