PRODUCT PRESENTATION

The PHILISUN OSFP (FIN) to 2×QSFP112 is a 2×400Gb/s dual-port active electrical breakout cable, designed with a heatsink-equipped OSFP connector to dual 400G QSFP112 connectors. This product fully complies with OSFP MSA Rev 5.0, IEEE 802.3ck, CMIS 5.0, and SFF-8679 standards.Integrating active components and retimer chips, the AEC cable effectively compensates for signal attenuation during high-speed PAM4 transmission. It delivers reliable, low-power, and low-latency plug-and-play connectivity at up to 800Gbps over a maximum distance of 5 meters.It is ideally suited for inter-rack connections in telecommunications and data center environments, providing an optimal balance of performance and efficiency for high-density infrastructure deployments.
