Description
The AddOn QSFPDD-8SFP28-PDAC2M-AO is a high-performance 200GBase-CU QSFP-DD to 8xSFP28 direct attach cable designed for reliable short-distance, high-bandwidth connectivity in data centers, enterprise networks, and high-performance computing environments. Operating over passive copper with a maximum reach of 2 meters (6.6 ft), this cable delivers robust signal integrity, low latency, and superior EMI/EMC performance.
Compliant with QSFP-DD MSA, IEEE 802.3Bj/By/CD standards, and SFF-8679/SFF-8636 specifications, it supports 28 Gbps per lane (NRZ) and is engineered for seamless integration with switches, routers, and servers. The cable is RoHS-6 compliant, features I²C EEPROM support, and utilizes a pull-to-release latch design for secure, easy installation. It is also TAA compliant, ensuring eligibility for U.S. Government procurement.
Each AddOn cable undergoes rigorous programming, serialization, and application testing to guarantee full compatibility and reliability. Backed by a limited lifetime warranty, it’s a cost-effective, plug-and-play solution for scalable, high-density networking deployments.
