Abstract: The present disclosure provides an encoding and decoding device implementing an improved forward error correction (FEC) coding/decoding method. In particular, the encoding device is configured to encode a stream of data symbols using a spatially coupled code (e.g. staircase codes, braided block codes or continuously interleaved block codes), wherein at least one generalized error location (GEL) code is used as a component code of the spatially coupled code. Accordingly, the decoding device is configured to decode a sequence of encoded symbol blocks using a spatially coupled code, wherein at least one GEL code is used as a component code of the spatially coupled code. Thereby, a suitable spatially coupled FEC code that allows for very low-latency, high-throughput, high-rate applications with a low-complexity decoding procedure, and allows for mitigation of the error-floor, is designed.

Abstract: A signal pre-compensation method is provided. In the method, at least one target frequency subband is determined from a plurality of frequency subbands of a first optical signal and an optical signal of the at least one target frequency subband in the first optical signal is demodulated based on the at least one target frequency subband. A first electrical signal is obtained after demodulation, and a pre-compensation parameter is updated based on the at least one target frequency subband, the first electrical signal, and a second electrical signal. Herein the pre-compensation parameter is used to perform signal pre-compensation on the second electrical signal, and the first optical signal is generated after the pre-compensation is performed on the second electrical signal.

Abstract: A heat dissipation cabinet includes a cabinet body and a heat dissipation apparatus. A first accommodation region of the cabinet body can accommodate a plugboard in a stacked manner, and heat source components of the plugboard dissipate heat through the heat dissipation apparatus. An evaporator, a condenser, and an evaporation pipeline of the heat dissipation apparatus are connected to a liquid return pipeline to form a heat exchange loop, and the evaporator is in thermal contact with an outer surface of a heat source component. The condenser is disposed in a second accommodation region and located above the evaporator. A refrigerant flows in the heat exchange loop, to draw heat of the heat source component far to the condenser, and take away heat of the condenser using air generated by a fan. A second accommodation region is used as an independent air duct whose path is relatively short.
