3m(10ft) Cisco Compatible 800G OSFP Finned Top to 2 x 400G OSFP Flat Top Ethernet Passive Direct Attach Copper Breakout Cable
The 800G OSFP Direct Attach Cable operates over passive copper, which requires no additional power to ensure quality connectivity. This breakout cable is compliant with OSFP MSA(Multi-Source Agreement) and IEEE 802.3ck standards. It provides a high-speed connection of an 800G OSFP port on one end and two 400G OSFP ports on the other end. Each end contains EEPROM coding that offers product identification and characteristics to the host system. It is power-efficient and suitable for cost-effective close-range interconnections within the equipment room of telecom operators or data centers, etc.
