LE2D2L16QX2H FAQ
Q1: What are the maximum single-port speed and transmission distance of the Huawei LE2D2L16QX2H interface card? Does it support hot-swapping?
A1: Maximum single-port speed is 40Gbps, and maximum transmission distance is 40km (single-mode) / 0.3km (multi-mode); it supports QSFP+ module hot-swapping, ensuring uninterrupted service during maintenance.
Q2: Is this interface card compatible with Huawei S5735-E switches? How many cards can a single S12712 unit support at most?
A2: Fully compatible with S5735-E switches (requires upgrading to the latest system version); a single S12712 unit supports a maximum of 8 cards, providing 128 40G ports to meet the expansion needs of ultra-large networks.
Q3: What are the core advantages of the LE2D2L16QX2H compared to 12-port / 8-port 40G interface cards?
A3: Single-slot port density is increased by 33%-100%, and slot occupancy is reduced by 25%-50% for the same 40G port requirement; single-port procurement cost is 20% lower, resulting in a significant total cost advantage during large-scale deployment and higher expansion efficiency.
