The rapid development of technology cannot be separated from high-speed and high-bandwidth data transmission. Traditional 10 Gigabit Ethernet can no longer meet this demand, so 400G Ethernet technology has become a new hot spot. The 400G OSFP To QSFP-DD DAC cable, as a key component of the connector, has also come to the fore.

Product Features:

• 400Gbps OSFP To QSFP-DD Passive High Speed Cable

• Products comply with CMIS 4.0, OSFP-MSA, QSFP-DD MSA standards

• Ethernet compliant with IEEE802.3cd

• Supports 56G (PAM4) electrical data rate/channel

• Supports I2C two-wire string interface for easy control

• Supports hot-plugging

• Low crosstalk/low power

• Transmission distance up to 3 meters

• ROHS compliant

OSFP is an eight-channel compact pluggable optical module that contains eight high-speed electrical channels running at 50Gb/s each, for a total bandwidth of 400Gb/s and realizes a 400G OSFP interconnect ecosystem. This will greatly assist legacy OSFP users in upgrading their link bandwidth to 400G per port at a lower cost and shorter transition time.

OSFP-DD (Quad Small Form Factor Pluggable Dual Density) doubles OSFP interconnect density with an 8-channel electrical interface capable of 28Gbps NRZ or 56Gbps PAM-4 for 200 or 400 Gbps per port aggregation, and backwards compatibility of the OSFP-DD portfolio allows existing QSFP modules to be plugged into QSFP-DD ports, providing low loss with less skew. With good thermal and signal integrity performance.

In addition to this, the 400G OSFP to QSFP-DD DAC cable utilizes a Twin Dense Twisted Pair (Twinax) architecture that combines both OSFP and QSFP-DD standards. This makes it a huge improvement in transmission speed, power consumption, and density. It is widely used in 400G Ethernet, switches, routers, data centers, cloud servers, data storage and communication industries.
