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 (µ-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.
