The backbone of next-generation optical transport is evolving rapidly to support much higher data rates while also supporting a variety of applications (voice, video, storage). OTN allows carriers to scale quickly to support the tremendous growth of traffic on their networks.
Altera is committed to support next-generation OTN designs by offering silicon optimized for transport applications as well as system-level solutions that will enable a single-chip solution for Transponder, Muxponder and Regenerator applications.
Altera’s innovations for OTN include :
High-Speed Transceivers
OTN systems require robust transceivers that can scale up to 12.5Gbps and 28Gbps to support 100G and 400G applications. Altera has established itself as the leader in transceiver technology.
ASIC Technologies
Altera is committed to offering solutions that can scale to production level volumes. Hardcopy ASICs deliver the lowest total cost, risk, and power consumption when you're ready to take your FPGA prototype designs to volume production.
Partial Reconfiguration
Altera’s 28nm devices support partial reconfiguration which will allow for portions of the FPGA to be reconfigured without impacting the rest of the device. This is a valuable feature for client interfaces in OTN platforms which require support of multiple interfaces (Ethernet, SONET, OTN, Fiberchannel) that change over time. This enables you to reduce the size of FPGAs, saving board space, cost, and power.
Fractional-PLLs
Board space, cost and power consumption are key issues for transport systems which is driving Altera to integrate more functionality into our silicon.
Fractional phase-locked loops (fPLLs), which are embedded in our Stratix V devices, provide increased clocking flexibility and replace on-board voltage-controlled crystal oscillators (VCXOs)
OTN System IP
Altera’s IP portfolio is unmatched in the industry and supports entire OTN systems on a single device. The IP scales from OTU2 through OTU4 and supports ODU multiplexing including ODU0 and ODUFlex. Altera also can support Segmentation and Reassembly (SAR) and fabric interfaces needed for Packet Optical Transport Systems (P-OTS).
