TJ1600 product family overview

TJ1600 is a comprehensive metro aggregation and metro core solution, which can be deployed in various configurations from 10GbE PTN aggregation/core or hybrid NG-SDH and PTN aggregation/core configurations or NG-SDH/SONET ADM/MADM/DXC/DWDM. The product provides a diverse range of data and circuit interfaces in one of the highest densities in products of its class.

Digital cross-connect at fine granularity and data switching functionality along with the modular nature of the interfaces provide carriers with very flexible options for configuring the product in networks.

Following are the key features:

• One device for Packet, TDM and DWDM: Balances Packet and TDM transport in a unique way. Its hybrid architecture allows for three configurations; TDM with Packet Transport, Hybrid TDM and Packet Transport and all DWDM Optical Transport using the same hardware, software and features.
• Flexible Packet and TDM switching: Quickly and easily adapts to changes in service types and bandwidth with a scalable Packet switch provisioned separately from the TDM switch.
• Services optimization: Services can be matched to the best transport technology whether it is maximizing efficiency with Stat-muxing, reducing costs by using OTN switching to by-pass routers, maximizing fiber utilization with DWDM or minimizing latency with optical/OTN switching.
• Optimizing Packet to DWDM interworking: TJ1600 optimizes 1G, 10G and 100G transport by using OTN switching to efficiently pack and route traffic through the network.
• Greater DWDM reach: Optimized fiber utilization using the latest technology for reliable transport in metro, regional, and long haul networks. For both the POTP and DWDM applications, common integrated and standalone additional DWDM optical elements such as Optical Fiber Amplifiers (OFA), optical Multiplexer and Demultiplexer Units (MDU) are used to transport and add/drop multichannel, high speed DWDM wavelengths. Using various types of OFAs and advanced forward error correction codes (FEC), transmission can be reached to longer distances in the optical domain before electrical regeneration is required.
• SONET/SDH/front-haul: Provides reliability and performance expected of the transport network;exceptional performance, deterministic routes, predictable latency, low protection switch times and easy network planning.

  NOTE:This document mentions SDH interfaces and not SONET interfaces. Tributary card which supports SDH interface also supports corresponding SONET interface when the node is configured in SONET mode.

• Advanced Ethernet features: Provides best in class packet switching to create networks with the highest performance. Provides MPLS-TP based pseudowires for traffic engineered flows on trunks, which optimizes the network by providing the right amount of control.
• ASON and WSON GMPLS control plane: TJ1600 platform supports 1+Reroute and 1+1+ Reroute options by implementing standard protocols.
• Flexible Network Architectures: Powered with flexible architecture that allows to build the network best suited for all services.
