Alcatel-Lucent announced upgrades to several products Wednesday that represent a mix of former Alcatel and Lucent products.
The company added integrated multi-degree reconfigurable optical add/drop multiplexer functionality to its 1850 TSS transport switch and boosted its capacity from 100 Gb/s to 320 Gb/s. It also introduced a smaller 3 Gb/s version, the 1850 TSS-3, for access networks, meant to handle business services and mobile backhaul. In addition to 1 Gb/s Ethernet trunks, the TSS-3 also includes plesiochronous digital hierarchy uplinks to carry Ethernet services over existing copper lines.
Alcatel-Lucent also introduced a new 48-port line card for its 7330 fiber-to-the-node (FTTN) platform that enables VDSL2 bonding, a technology that uses multiple copper pairs to boost the bandwidth and reach of VDSL2-based services. AT&T, a customer of Alcatel-Lucent’s FTTN gear, has vowed to use VDSL2 bonding to increase the speed of its FTTN network to handle bandwidth-rich services such as high-definition television.
“[VDSL2 bonding] doubles the bandwidth and the reach of services, maximizing efficiency from an IP port perspective,” said Cindy Christy, president of Alcatel-Lucent’s North American operations.
Along with those former Alcatel products, the company introduced a new version of Lucent’s former 1675 LambdaUnite optical cross-connect, which now includes external network-to-network interfaces based on Automatically Switched Optical Networks, or ASON, for provisioning connections in optical networks.
“ASON is entering a more sophisticated application stage in multi-vendor network environments,” the company said, and carriers can be comfortable using the new 1675 with ASON-based gear from other vendors.
