Munich-based connections systems manufacturer Yamaichi Electronics, has extended its QSFP range of high-speed connectors for the data networking market with the QSFP56 host connector. The QSFP56 host connector supports HDR 200G Infiniband and is able to transmit signals at 56 Gbps per channel. In addition, it compliant with the SFF- 8436 and SFF-8662 standards as a card-edge-to-transceiver module interface.

With type ‘A’ PCB footprint, the QSFP56 has a 38-pin count, which is the same as of previous, lower-speed versions, including QSFP, QSFP+ and QSFP28. All contacts are gold-plated 0.76 μm min. for reliable, high-speed data transmission, and designed for SMT mounting and the physical interface is compatible with the previous versions. There is also a cage, heatsink, heatsink clip and light pipe available as optional components, meaning the customer can choose the ideal connector configuration from a package of host connector and mechanical kit.

Yamaichi Electronics has also developed the QSFP-DD connector, which like the QSFP56 is in mass production and available commercially. Yamaichi says that recent measurements have proven that the signal integrity of the current QSFP-DD design fully complies with IEEE 802.3 ck (112 Gb/ch PAM4 modulation), and claims this outstanding electrical performance is unique on the market so far.
