Brief Introduction
The Vchung 800Gb/s twin-port OSFPto 2x400Gb/s OSFP passive Active Copper Cable (ACC) dual breakout (aka splitter) cable. The ACC uses 8-channels of 100G-PAM4 modulation and has lengths of 4 and 5 meters. It has identical design and internals as the QSFP112 version, only with different connector shells. The ACC firmware supports both InfiniBand and Ethernet and is automatically enabled depending on the protocol of the switch attached to. The 8-channel, twin-port, OSFP end uses a finned top form-factor for use in Quantum-2 and Spectrum-4 switch cages. The four 200G ends support 2-channels of 100G-PAM4 (400G) use a flat top OSFP for use in ConnectX-7 adapters using riding heat sinks on the connector cage. For use in liquid-cooled systems, a twin-port OSFP version is available with a flat top (designated -FLT in the part number). ACC cables are the second lowest-cost, low-latency, low-power consuming, high-speed links next to passive DACs due to their simplicity of design and minimal components. The “active” term refers to the passive copper cable with an equalizer integrated circuit to extend the length to 4 and 5-meters while maintaining low-latency and low-power at 1.5 Watts and 0.6 Watts. Thin 30AWG is used for 4m lengths and thicker 26AWG for 5m. Each end includes an EEPROM which provides product identification and characteristics to the host system. Main use is linking an 800Gb/s Quantum-2 switch or Spectrum-4 switch to OSFP-based 200Gb/s ConnectX-7 PCIe network adapter cards.

 | Optical transceivers port(LC) For LC port, there are two types of single-fiber bidirectional optical transceivers (one LC connector) and dual-fiber unidirectional optical transceiver (two LC connectors). Single fiber bidirectional is used to send and receive signals in one fiber, and dual fiber unidirectional optical transceivers are used to one fiber to send signals and other fiber to receive signals. |
