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.
