400G QSFP-DD to 100G QSFP56 Breakout Cable
Hilink HL-QS400G-4QS28-DAC 400G QSFP-DD to 4 QSFP56 Passive Cables assembly feature eight differential copper pairs, providing four data transmission channels at speeds up to 56Gbps(PAM4) per channel and meets 400G Ethernet and InfiniBand Enhanced Data Rate(EDR) requirements.
Description
A 400G QSFP-DD (Quad Small Form-Factor Pluggable Double Density) to 100G QSFP56 (Quad Small Form-Factor Pluggable 56) breakout cable is a type of fiber optic cable that is used to connect networking devices that use different types of transceivers.
QSFP-DD and QSFP56 are both types of transceivers that are used for transmitting and receiving data over fiber optic cables. QSFP-DD is a newer and more advanced transceiver that is capable of transmitting data at a higher rate than QSFP56.
A breakout cable is a type of cable that has multiple connectors at each end, allowing it to connect to multiple devices or ports simultaneously. In this case, a 400G QSFP-DD to 100G QSFP56 breakout cable would have a QSFP-DD connector at one end and four QSFP56 connectors at the other end.
This type of cable would be used to connect a device that uses a 400G QSFP-DD transceiver, such as a high-speed networking switch, to four devices that use 100G QSFP28 transceivers, such as servers or storage devices. It allows the device with the QSFP-DD transceiver to communicate with the devices with QSFP56 transceivers at a lower data rate of 100 Gbps.
400G QSFP-DD to 100G QSFP56 breakout cables are an important component of modern networking and communications systems, as they allow for the interconnection of devices with different transceiver types and data rates.
