Data Center Access Consolidation for Scalable Infrastructure
In data center environments where dense Layer 2 and Layer 3 connectivity is required, the Huawei ES1D2G48SX5H Interface Card plays a critical role by providing high-density optically connected ports within the Huawei S7700 series chassis. The card supports scalable uplinks via SFP interfaces, accommodating diverse fiber distance demands and minimizing latency. Its distributed forwarding architecture balances traffic loads to maximize throughput. This integration improves switch fabric efficiency and simplifies network topology, enabling data centers to respond to increasing bandwidth requirements and evolving service needs while maintaining operational excellence and compliance with industry protocols.


ES1D2G48SX5H FAQ

Q1: Is it compatible with Huawei S9708 switches? Will there be bandwidth bottlenecks with 48 ports operating at full load simultaneously and ultra-long-distance transmission over 120km?

A1: Fully compatible! Supports the entire S9300/S9700 series, with backplane bandwidth ≥48Gbps. Full-load transmission is bottleneck-free, and the low insertion loss design ensures stable ultra-long-distance transmission, meeting cross-city access needs.

Q2: How is the signal stability when using ZE modules for 120km ultra-long-distance transmission? Is it compatible with third-party compliant SFP modules?

A2: Signal attenuation <1dB within 120km, with no packet loss or latency fluctuations. Huawei original modules are preferred, but IEEE standard third-party modules are also compatible, offering flexible adaptation and controllable costs.

Q3: How to choose between 24/32-port / standard long-distance high-end line boards?

A3: 24 ports are suitable for <30 devices, 32 ports are suitable for 30-40 devices, and the standard long-distance model only supports ≤80km; for more than 40 devices and ultra-long-distance requirements of 80km-120km, this product offers the best cost performance.
