Optical module rate adaptation

Home / Optical module rate adaptation

The present disclosure relates to a method, an apparatus, a medium, and a device for adapting an optical port rate of a network communication device, the method including: after detecting that an optical module corresponding to an optical fiber interface is in place . While the industry-standard OSFP (Octal Small Form-Factor Pluggable) module has successfully enabled 400Gbps, 800Gbps, and 1. Abstract: In this paper, we propose a rate-adaptive FEC scheme based on LDPC codes together with its software reconfigurable unified FPGA architecture. It utilizes a mapping method through weighted summation, enabling an even increase of bit energy. Industry pundits have recently speculated that demand for 100G/400G switches may take off in 2019, prompting optical transceiver module vendors to sample data center switches with high data transmission rates earlier than expected. Abstract—Rate-adaptive optical transceivers can play an impor-tant role in exploiting the available resources in dynamic optical networks, in which different links yield different signal qualities.

Rate-Adaptive Coded Modulation for Fiber-Optic Communications

We study rate-adaptive joint coding and modulation, often called coded modulation (CM), addressing non-dispersion-managed (non-DM) links, exploiting recent advances in channel modeling of these links.

Rate Adaptation

The M-D rate adaptation consists in adapting the rate as fast as possible, every 15 minutes here, solely based on the last monitored SNR value, i.e. the SNR averaged over the previous 15 minutes.
