Amphenol Commercial QSFP Double Density (DD) Interconnect System

Amphenol Commercial QSFP Double Density (DD) Interconnect System is backward-mating compatible with QSFP products. The connectors utilize an electrical interface with eight lanes that support 25Gb/s NRZ modulation or 56Gb/s PAM4, providing solutions up to 400Gb/s aggregate bandwidth. The 76-position, 0.8mm-pitch connectors enable up to 14.4Tb/s aggregate bandwidth in a single switch slot. The connector and cage design is backward compatible with QSFP28 modules, which can be inserted into a QSFP DD port and connected to four of the eight electrical channels. Amphenol Commercial QSFP DD Interconnect System is ideal for communications, industrial and instrumentation, and data applications.
