PRODUCT PRESENTATION

The PHILISUN 800G OSFP(FIN) to 4×200G QSFP112 passive high-speed cable leverages passive twinax copper transmission to deliver stable, high-performance links with no external power required. It fully complies with OSFP MSA, QSFP112 MSA, IEEE 802.3ck, and CMIS v5.0 specifications. Engineered with one finned 800G OSFP port for switch connectivity and four 200G QSFP112 ports for network interface cards (NICs) on the opposing end, it enables seamless 800G-to-4×200G breakout.Featuring a simplified design and minimal component count, this passive DAC solution achieves the lowest cost, ultra-low latency, and near-zero power consumption for high-speed interconnections. It is optimized for short-range links in telecom infrastructure and data centers, delivering a highly efficient, energy-saving, and cost-effective connectivity solution.
