200G QSFP56 AOC and 200G QSFP56 Breakout AOC are two types of active optical cables that can be used for high-speed data center connectivity. They both have a QSFP56 form factor, which means they have four channels of 50Gbps each, but they use different modulation schemes and have different applications.<\/p>\n\n\n\n
200G QSFP56 AOC<\/a> uses PAM4 modulation, which means it encodes two bits per symbol, resulting in a higher data rate per channel. It is compatible with 200G Ethernet and InfiniBand HDR standards, and can support distances up to 30 meters. It is ideal for short-reach interconnects between switches, servers, and storage devices.<\/p>\n\n\n\n 200G QSFP56<\/a> AOC is compatible with 200G Ethernet and InfiniBand HDR standards, which are protocols that define how data is transmitted and received over a network. 200G Ethernet is a standard that supports data rates of up to 200 gigabits per second (Gbps) over a single optical fiber or copper cable. InfiniBand<\/a> HDR is a standard that supports data rates of up to 200 Gbps over a single lane or up to 800 Gbps over four lanes of a parallel optical cable. Both standards use PAM4 modulation to achieve higher bandwidth and efficiency.<\/p>\n\n\n\n 200G QSFP56 AOC can support distances up to 30 meters, which is suitable for short-reach interconnects between switches, servers, and storage devices in a data center. It has low power consumption and high reliability, making it an ideal choice for high-performance computing and cloud applications.<\/p>\n\n\n\n
