100G Packet-Optical Chips Drive OTN Deployment
Packet-optical transport is now widely used by carriers across their networks. It brings the advantages of Sonet/SDH (synchronous digital hierarchy), dense wavelength division multiplexing (DWDM) and packet-based networks, delivering a scalable and resilient transport infrastructure. Packet-optical transport is used in the core of the network providing a highly reliable long distance connection, in the metro providing a high bandwidth and resilient network and at the edge delivering carrier grade services to enterprises.

Semiconductor components are key to the continued success packet-optical transport networks. Vendors have developed highly integrated system on chip (SoC) solutions at 10 Gbit/s, 40 Gbit/s and now 100 Gbit/s, supporting a complex mix of interfaces, functionality and performance. Also available are field-programmable gate arrays (FPGAs) with almost 100 serial interfaces and a wide range of optical transport network (OTN) and Ethernet IP blocks. Using these solutions, telecom equipment manufacturers can develop highly integrated reconfigurable optical add-drop multiplexers (ROADM), P-OTP and micro OTP (-OTP) systems that address carriers' requirements.

Packet-optical transport is a key focus for both carriers and telecom equipment manufacturers. There are now have a wide range of 10Gbit/s, 40Gbit/s and 100Gbit/s OTN framer/mapper devices and integrated packet-optical transport devices from AppliedMicro, Cortina Systems, IP Light, PMC-Sierra and Vitesse. Altera and Xilinx have made significant efforts to ensure the latest FPGA's support the high data rate interfaces required for packet-optical transport devices. By using internal developments, making acquisitions and working with third-party IP vendors, such as Xelic, both Altera and Xilinx are offering customers a quick development solution for FPGA-based integrated optical transport devices.

All the leading vendors are already working on solutions for the next-generation 100G systems with support for 28Gbit/s serial interfaces and CFP2 optical modules. Time to market, flexibility and integration will be key parameters as telecom equipment providers choose their next-generation packet-optical transport technology. The winners will be those that can show market leading performance and integration at 10 Gbit/s, 40 Gbit/s and 100 Gbit/s, with a clear roadmap to 400G within one to two years.

100G Packet-Optical Chips Drive OTN Deployment details and analyzes integrated packet-optical devices and OTN framer/mapper devices and technologies, identifying the key requirements and the highlighting the advantages they hold for equipment manufacturers. It also surveys component availability, reviewing features, performance and flexibility. The report covers more than 50 devices and profiles nine vendors in this important market.

Table of Contents (cci0713_toc.pdf)
The following excerpt shows a P-OTP with a central OTN, Sonet/SDH and packet fabric switch. Optical line cards connect the system to the optical transport network. Transponder, muxponder and client cards connect the system to high-rate and low-rate OTN, Ethernet, Sonet/SDH and Fibre Channel networks. These systems contain multiple OTN framer/mapper or integrated packet-optical transport devices. OTN framer/mapper devices can also be used to build regenerators and aggregation systems.
