P4HF FAQ
Q1: What is the maximum transmission distance per port of the Huawei P4HF interface card? Does it support hot-swapping?
A1: The maximum transmission distance per port is 100km (when paired with a QSFP-DD 400G ER8 module); it supports hot-swapping of the module and interface card, ensuring uninterrupted service during maintenance.
Q2: What are the core differences between the P4HF and P4CF interface cards? Is it compatible with S7703 switches?
A2: The core difference lies in the maximum transmission distance (P4HF 100km vs P4CF 80km); it is compatible with S7703 switches (requires upgrading to the latest system version), with a maximum of 2 cards supported per unit.
Q3: What are the advantages of the P4HF compared to other 400G long-distance interface cards of the same type?
A3: With the same 100km transmission capacity, the port density is twice as high, and slot usage is reduced by 50%; it is compatible with all Huawei high-end switches, requiring no additional adaptation costs, and long-term maintenance costs are 30% lower.
