O4Q112-800G-ACC is a passive copper cable with integrated equalizer circuit. It can extend the length up to 4 meters and 5 meters while maintaining low latency and low power consumption of 1.5W and 0.6W respectively."}},{"@type":"Question","name":"What are the main application scenarios for the O4Q112-800G-DAC cable?","acceptedAnswer":{"@type":"Answer","text":"It is mainly used for switches with OSFP ports, with the branch end connected to a 200G QSFP112 port of either ConnextX-7 network card or BlueFIeld-3 DPU."}},{"@type":"Question","name":"Can the O4Q112-800G-DAC cable be used for 200G network cards with OSFP ports?","acceptedAnswer":{"@type":"Answer","text":"No, it cannot be used. QSFP112 and OSFP are two different form factors with inconsistent sizes, and they cannot be used together."}},{"@type":"Question","name":"Can the branch end of the O4Q112-800G-DAC cable be used for a 400G QSFP112 port network card?","acceptedAnswer":{"@type":"Answer","text":"In general, 400G QSFP112 network cards can support lower speeds such as 200G, so you can use this cable."}}]}

Cisco Compatible Passive Copper Splitter Cable, Twin Port 800Gb/s to 4x200Gb/s, OSFP Finned Top to 4xQSFP112 Flat Top, 1m
NADDOD O4Q112-800G-CU1 is an 800Gb/s Twin-port OSFP (Octal Small Form-factor Pluggable) Finned Top to 4x200Gb/s QSFP112 (Quad Small Form-factor Pluggable 112G) Flat Top passive Direct Attach Copper (DAC) quad breakout (aka splitter) cable for End-to-End Ethernet solutions. The 8-channel Twin port OSFP end uses a finned top form-factor for use in OSFP switch cages. The four 200G ends support 2-channels of 100G-PAM4 (200G) and use a flat top QSFP112 connector cage adapters. DAC cables are the lowest-cost, lowest-latency, near zero power consuming high-speed links available due to their simplicity of design and minimal components.
NADDOD modules, AOCs, and DACs are professionally tested and fully compatible with the latest mainstream devices of Arista 7060X6 series data center switches, NVIDIA Spectrum-4 SN5000 series, Cisco Nexus 9300-GX2 series and Broadcom NIC BCM957608 series, which guarantees unmatched interoperability, high reliability and seamless operation in complex RoCE applications.
In the RS-FEC(544,514) test, NADDOD products achieve pre-FEC BER of -9~-11, and near-zero post-FEC BER, which can meet the strict requirements for high performance and stable networking connection.
