Yamaichi Electronics has unveiled a host connector for SFP28 connections using 56-Gbps PAM4 modulation per channel. The company foresees the connector being used in server and switch applications.
The company states the connector is fully compliant with the SFF-8084 and SFF-8402 standards as an interface connector to plug in a 0.8-mm pitch card edge connector. The connector is thus mechanically compatible with other SFP connector generations such as those for 10-Gbps and 16-Gbps applications. It also can be used in replacement scenarios, as it has the same footprint as that of older card edge SFP module generations.
The pin count is 20 pins. All contacts are plated gold 0.76-μm minimum thickness and are therefore reliable for high-speed transmission, says Yamaichi. The connector is designed for SMT mounting. The contact pitch is 0.8 mm. The mating cycle is 100 times.
