Optical four-level pulse amplitude modulation (PAM-4) is being widely studied for various short-reach optical interfaces, motivated by the need to keep cost structure low, and to increase link capacity despite various constraints in component bandwidth. When considering PAM-4 in applications with reach significantly greater than 10 km, such as in extended data center interconnects which require optical...
100G DP-QPSK transmission can use programmable SD-FEC to trade-off latency against coding gain. Albeit inferior to 10G ultra-low latency implementations, such a solution can approach state-of-the art 10G G.709 FEC transmission in latency and performance while offering a 10x capacity increase.
The benefits of bitrate-adaptive colored interfaces in packet optical core networks with time-varying traffic load are investigated. Significant energy savings are obtained for different traffic scenarios without the need to re-route traffic.
Adaptation of the signal bandwidth or the data rate to the channel reach in optical networks is discussed. Network improvement is considered, and an implementation option is presented.
Efforts towards commercializing higher-speed optical transmission have demonstrated the need for advanced modulation formats, several of which require similar transceiver hardware architecture. Adaptive transceivers can be built which have different operational configurations controlled by software. These software-defined transceiver configurations support a set of specific modulation / demodulation...
