The 400G OSFP to QSFP-DD DAC solution is a high-speed, high-bandwidth data transmission solution designed to meet the growing demand for data transfer, particularly as 400G Ethernet technology becomes a new focus. The key components of this solution include the 400Gbps OSFP to QSFP-DD passive high-speed cable, which complies with CMIS4.0, OSFP-MSA, QSFP-DD MSA standards, and IEEE802.3cd standard, supporting a 56G (PAM4) electrical data rate per channel. Additionally, it supports the I2C two-wire serial interface, is easy to control, supports hot-swapping, has low crosstalk/low power characteristics, and is RoHS compliant.

OSFP (Octal Small Form-factor Pluggable) is an eight-channel small form-factor pluggable optical module. It includes eight high-speed electrical channels, each operating at 50Gb/s, resulting in a total bandwidth of 400Gb/s, thus establishing a 400G OSFP interconnection ecosystem. This will greatly assist traditional OSFP users in upgrading their link bandwidth to 400G per port at a lower cost and with shorter transition times.
OSFP-DD (Quad Small Form-factor Pluggable Double Density) doubles the interconnection density of OSFP through its 8-channel electrical interface, enabling 28Gbps NRZ or 56Gbps PAM-4, thus achieving 200 or 400 Gbps aggregation per port. The backward compatibility of the OSFP-DD product line allows existing QSFP modules to be inserted into QSFP-DD ports, providing low loss and reduced skew. It also has excellent thermal and signal integrity performance.
Moreover, the 400G OSFP to QSFP-DD DAC cable uses a Twinax architecture that combines the standards of OSFP and QSFP-DD. This results in significant improvements in transmission speed, power consumption, and density. The product is widely used in 400G Ethernet, switches, routers, data centers, cloud servers, data storage, and the communications industry.

Frequently Asked Questions
Q: Can 400G QSFP-DD optical modules be inserted into OSFP ports?
A: No, because QSFP-DD and OSFP have different structures and sizes. For example, QSFP-DD uses a quad-channel small form-factor double density design, while OSFP uses an eight-channel small form-factor pluggable design. Moreover, the QSFP package is larger than the QSFP-DD package, making them incompatible. If your network equipment uses QSFP-DD packaging, you must use QSFP-DD optical modules, QSFP-DD DAC, or QSFP-DD AOC.
Q: Besides the QSFP-DD optical modules mentioned above, what other 400G products are available?
A: There are also 400G QSFP-DD DACs and AOCs. For more information on 400G DACs and AOCs, you can visit the article “How Much Do You Know About 400G DAC and 400G AOC?”
Q: Can 100G QSFP28 optical modules be inserted into QSFP-DD ports?
A: Yes, since QSFP-DD packaging is backward compatible. You can configure the QSFP-DD port to operate at 100G and then insert a 100G QSFP28 optical module, resulting in a 100G link transmission rate.
