Huawei 10 Gigabit Optical Port Network Switch

Huawei 10 Gigabit switches typically use 10GE SFP+ optical ports for downlink connections and QSFP+ ports for uplinks, supporting various optical modules and cables for flexible deployment.

Port Types and Configurations

Huawei 10GE switches, such as the CloudEngine S6730-H-V2 and S6720S series, are equipped with 10GE SFP+ downlink ports for connecting servers or access devices, and 40GE or 100GE QSFP+ uplink ports for higher bandwidth aggregation . For example, the S6720S-26Q-LI-24S-AC model has 24 downlink 10GE SFP+ ports and 2 uplink 40GE QSFP+ ports, allowing future network upgrades . The CE8800 series also supports 24-port 10GE SFP+ subcards with QSFP28 uplinks for data center applications .

Compatible Optical Modules

Huawei 10GE SFP+ ports support a variety of optical modules:

• Multimode modules (e.g., 10GBASE-SR) with OM3/OM4 patch cords, supporting distances up to 300 meters .
• Single-mode modules (e.g., 10GBASE-LR, 10GBASE-ER) for longer distances, typically 10 km to 40 km, depending on module specifications .
• Bidirectional (BIDI) single-fiber modules, which must be used in pairs (e.g., SFP-10G-BXD1 with SFP-10G-BXU1) to enable full-duplex communication over a single fiber .

Cable Options

Depending on distance and deployment scenario, Huawei 10GE SFP+ ports can use:

• DAC (Direct Attach Copper) cables for short distances (~7 meters), ideal for server-to-switch connections .
• AOC (Active Optical Cables) for medium distances up to 300 meters, providing flexibility without separate transceivers .
• Standard optical fiber with SFP+ modules for longer distances, using either multimode or single-mode fiber .

Deployment Considerations

• Server connectivity: 10GE SFP+ ports connect directly to server NICs with SFP+ modules or DAC/AOC cables. Intel 10G NICs typically have two independent SFP+ ports for redundancy or aggregation .
• Uplink aggregation: QSFP+ uplinks can be used for 40GE or 100GE connections to core switches, supporting future bandwidth expansion .
• Network management: Huawei switches support cloud management, VXLAN, and telemetry features, ensuring high performance and simplified O&M for enterprise and data center networks .

Summary

Huawei 10 Gigabit switches provide flexible optical connectivity through SFP+ downlink ports and QSFP+ uplinks, supporting multimode, single-mode, and BIDI optical modules. Deployment options include DAC, AOC, and fiber cables, allowing connections from short server links to long-distance aggregation. These switches are suitable for enterprise campuses, data centers, and high-performance networks, offering scalability, high reliability, and future-proof bandwidth expansion .
