ES0DG48CEAT0 FAQ

Q1: Is it compatible with Huawei S6720 switches? Will there be bandwidth bottlenecks when 48 combo ports simultaneously connect optical/electrical devices?

A1: Fully compatible! Supports the entire S5700/S6700 series, with backplane bandwidth ≥48Gbps. There are no bottlenecks when optical and electrical devices are simultaneously connected at full load, meeting the needs of medium-sized hybrid networks.

Q2: Can optical and electrical ports be switched freely? How is the transmission stability when connected to a 25km backbone node with an SFP optical module?

A2: Supports plug-and-play switching between optical and electrical modes on any port, no configuration required; signal attenuation is <0.4dB over 25km single-mode fiber transmission, and there is no packet loss during 55m Cat.5e electrical port transmission. Dual-mode stability is maximized.

Q3: How to choose between pure optical port/pure electrical port/high-end combo circuit boards?

A3: Pure optical port / pure electrical port is suitable for a single scenario; high-end combo models exceed the budget. If you need to connect to optical/electrical devices simultaneously or flexibly switch transmission methods, this product offers the best cost performance and compatibility.
