The current 10-Gbit OTN infrastructure is facing bandwidth exhaustion as the channels approach their maximum capacity. Faced with higher capital expenditure, higher operating expenditure, and shrinking revenue growth, service providers are turning to 100-Gbit OTN solutions to scale their current 10-Gbit-based networks by a factor of ten. However, there are large numbers of legacy OTN, SONET, Ethernet, and storage systems operating at lower data rates, which need to be plugged into the emerging optical infrastructure using 100-Gbit OTN muxponders. Altera’s Stratix V FPGA family contains a number of key innovations that directly address the needs of 100-Gbit OTN muxponder solutions.
