Questions & Answers
What are the advantages of OFNP sheath?
OFNP signifies a UL-certified plenum-rated cable jacket compliant with U.S. fire safety standards (NFPA 90A). It withstands long-term high-temperature exposure, exhibits excellent flame retardancy, and resists corrosion and stretching, making it suitable for use in ventilated areas as well as complex cabling environments.
What are the advantages of this cable?
This cable solves the interconnection issue between QSFP-DD switches and QSFP112 network cards, and compared to modules, it greatly reduces the interconnection cost.
What’s the electrical modulation on the QSFP-DD end of this cable? Is it compatible with 400G or 800G switches?
It supports 8×50G PAM4 modulation, compatible with the serdes of mainstream 400G QSFP-DD devices on the market, and can also be used with 800G QSFP-DD switches.
What are the common applications of this cable?
The 400G AOC cable is suitable for high-speed network transmission, data centres, cloud computing, and large-scale network device connections. It provides a high-speed, low-latency, reliable, and compatible data transmission solution.
