PRODUCT PRESENTATION

The PHILISUN OSFP(FIN) to 4×200G OSFP(FTL) is a 2×400Gb/s twin-port active direct attach copper (ACC) breakout cable, featuring a finned-top OSFP connector to four flat-top 200G OSFP connectors. It supports 100G-PAM4 modulation across eight high-speed copper pairs, each delivering up to 100Gb/s, and complies with IEEE 802.3ck, CMIS 5.0, and OSFP MSA Rev 5.0.
The finned-top connector enhances thermal cooling, while the flat-top connectors utilize cooling from adapter cages. Engineered to connect an 800Gb/s Spectrum-4 switch to four 200Gb/s ConnectX-7 OSFP modules, this cable integrates a redriver chip for transmission distances up to 5 meters with low latency. It improves bandwidth, density, and flexibility, making it ideal for power-efficient interconnections in data centers, AI/HPC clusters, and cross-rack applications.
