Does QSFPDD 400G DR4 support breakout?

QSFPDD 400G DR4 is an MPO interface, as long as the device port using the module supports the breakout function, then 400G DR4 can be paired with MPO to LC harness fiber to interconnect with the 100G DR module. This scenario is very common in the connection of 400G QDD switches to 100G QSFP28 switches.

The standard of QSFP56-DD is 8*50G, why are there only four channels in QSFPDD 400G DR4?

The optical module mainly completes the optical-electrical conversion work, for the number of its signal channels, there are two dimensions: an electrical signal (i.e., host side, connected to the device) and an optical signal (i.e., optical path side, connected to the optical fiber), the 8*50G is its electrical signal channel mode on the host side, and the DSP chip of the QDD-400G-DR4 module with the gearbox function, which can convert the electrical signals of the 8X50G into the 4X100G optical signal.

Which application scenarios are QSFPDD 400G DR4 generally used in?

The QDD-400G-DR4 transceiver is usually used to interconnect a 400G leaf switch with a spine, or a 400G QDD switch with a 100G QSFP28 switch, and as server NICs increase in speed, it can also be used to interconnect a 400G QDD switch with a 400G OSFP/QSFP112 NIC.

Can QSFPDD 400G DR4 be compatible with QSFP56 or QSFP28 ports?

No, QSFPDD ports can use QSFP56 or QSFP28 optical modules, but QSFPDD optical modules cannot be used on QSFP56/QSFP28 ports.

Questions & Answers

Ask a Question

Can OSFP ports use modules in QSFP-DD form factor, such as QDD-400G-DR4?

OSFP and QSFP-DD are two completely different form factors, so QSFP-DD optical modules like QDD-400G-FR4 QDD-400G-SR8, QDD-400G-LR4 or QDD-400G-DR4 all these optical transceivers cannot be used in OSFP ports.

Can QSFPDD 400G DR4 be interconnected with OSFP 400G DR4?

Even though QSFPDD and OSFP have different standards, QDD-400G-DR4 and OSFP-400G-DR4 are still interconnected and they have the same standards on the optical side; this is one way to interconnect NVIDIA CX7 OSFP-packaged 400G NICs with 400G QSFPDD switches.

What kind of patch cables for QSFPDD 400G DR4?

The QSFPDD 400G DR4 module's interface needs to be matched with a single-mode 12-core MPO interface, and the fiber connector needs to be an APC port.

We inquired about 400G QSFP-DD optical modules from several vendors at the same time, and NADDO's delivery time was the quickest. I received the modules quickly and was very happy with the service from the time I placed the order.
