ADTRAN Broadens Packet Optical Solution For Metro And Middle-Mile Applications

Stocks in this article: ADTN

ADTRAN®, Inc., (NASDAQ:ADTN), a leading provider of next-generation networking solutions, today announced a significant expansion of its Optical Networking Edge (ONE) portfolio with new capabilities that enable all optical multi-ring and mesh topologies required in metro and middle-mile networks. A new four-degree, scalable, compact Reconfigurable Optical Add/Drop Multiplexer (mini-ROADM) system-on-a-blade enables greater flexibility for service providers to respond to shifts in traffic and capacity demands in their residential, business, wholesale and mobile backhaul networks. The ONE portfolio also now doubles capacity for service providers with up to 88 wavelengths of 10 gigabit per second (Gbps) and allows for future upgrade to 100Gbps networking and services.

As service providers seek to increase flexibility, reduce network complexity and simplify operations, ADTRAN’s ONE platform supports applications deeper into the network from the access and edge to the metro and middle-mile. The flexibility of the four-degree, gridless mini-ROADM design reduces complexity in the network compared to alternative ROADM architectures that typically require a multi-blade implementation and a separate service delivery platform. The mini-ROADM design also simplifies agile optical network deployments by uniquely integrating into a single card the typical distributed and over-sized ROADM sub-elements, such as the amplifiers required to adjust for optical losses. These new features allow service providers to rapidly respond to customer requirements in dynamic markets like residential broadband, carrier Ethernet and 4G backhaul.

“Historically, ADTRAN has been very focused on optimizing its optical product line to support access applications at the network’s edge. That is until now,” said Ron Kline, Principal Analyst, Network Infrastructure, Ovum. “The new four-degree, grid-less ROADM for ADTRAN’s ONE converged packet optical product supports both 100GHz and 50GHz designs, extending ONE’s network role to support metro mesh-centric and middle-mile applications. The ROADM technology also gives operators a bridge between edge and core networks and provides the flexibility to evolve channel plans over time as higher speed wavelengths are deployed in the metro: 100G and ultimately even 400G.”
