EH1D2G48TFA0 FAQ
Q1: What are the core functions of this service board? How are the advantages of BiDi single-fiber and optoelectronic hybrid technology combined?
A1: It contains 48 10GE optoelectronic hybrid ports (SFP+/RJ45), supporting BiDi single-fiber bidirectional modules (2-40km) and 10G/1G dual rates; 48 ports provide ultra-high density + single-fiber bidirectional transmission, doubling fiber utilization, with low power consumption ≤208W, suitable for scenarios with limited fiber resources.
Q2: What are the core advantages compared to a regular 48-port optoelectronic hybrid board?
A2: The advantages are BiDi single-fiber compatibility (saving 50% of fiber), ultra-high density saving slots, and compatibility with both optical and electrical interfaces. It simultaneously solves the three major pain points of limited fiber resources, insufficient slots, and high power consumption in short- and medium-distance transmission, making it more suitable for dense deployment scenarios.
Q3: Does it require specific BiDi modules/cables? Which core protocols does it support?
A3: Compatible with Huawei standard SFP+ BiDi single-fiber bidirectional modules (including different transmission distances), ordinary dual-fiber optical modules, and Cat6a/Cat7 network cables; supports IPv4/IPv6 dual-stack, QoS, LACP, and flow control, meeting the high reliability requirements for short- and medium-distance transmission.
Q4: How to determine if this service board needs to be deployed? Is the installation complex?
A4: Deployment is recommended when large networks require 40+ mixed-interface terminal access, fiber optic resources are scarce, and the transmission distance is 2-40km; supports hot-swapping, installation requires no professional tools, and the ports automatically adapt to BiDi/ordinary modules and optical/electrical modes, making it plug-and-play.
