QSFP-DD Pluggable Module Connector and Cage Assembly

Milton Keynes, UK, June 10th, 2019: Cyntech Components, a specialist supplier of Yamaichi products; Yamaichi Electronics has expanded its high-speed connector product portfolio with a new small form factor connector for 400 Gigabit data networking applications and cage assembly mechanical parts.

QSFP-DD is one of the new small form factors. It was standardised by QSFP-DD MSA. Yamaichi Electronics is one of the active MSA members. QSFP-DD is similar to the current QSFP, but there are additional contact rows inside the structure design to realise double density by 8 channels for electrical signal transmission. Our mechanical design is QSFP-DD MSA compliant. It is also backwards compatible to the current QSFP.

Features and advantages

Yamaichi Electronics has a lot of experience in the design of high-speed connectors. The design structure and electrical performance of the new QSFP-DD connector benefits from this know-how and expertise. The connector is designed for 200G and 400G technologies and to support 28 Gbps per channel NRZ, and 56 Gbps per channel PAM4 modulation. Moreover the signal integrity takes into consideration 112Gbps per channel PAM4 modulation. This outstanding electrical performance is unique on the market so far.
