Does the S3700 series switch have an optical port

Yes, the Huawei S3700 series switches include optical ports, including SFP and combo interfaces.

Optical Port Details

The S3700 series switches are designed for enterprise network access and aggregation, and several models feature optical interfaces for uplinks and high-speed connections. For example, models like the S3700-52P-EI-24S-AC and S3700-52P-EI-24S-DC include:

• Twenty-four 100BASE-X Ethernet interfaces
• Two 100/1000BASE-X Ethernet optical interfaces
• Two GE SFP interfaces for fiber connectivity Other S3700 models, such as the S3700-28TP series, use combo interfaces that support both electrical (copper) and optical connections, allowing flexible deployment depending on network requirements .

Sub-card and Expansion Options

The S3700 series also supports optical sub-cards for additional uplink capacity. Supported sub-cards include:

• E4GF/E4GFA: 4-port GE optical
• X4SA: 4-port GE SFP/10G SFP+ optical
• E2XX/E2XY: 2-port 10GE XFP or SFP+ optical These sub-cards can be installed to expand the number of optical ports, providing flexibility for high-speed uplinks or fiber backbone connections.

Summary

In summary, the Huawei S3700 series does have optical ports, including dedicated SFP ports, 100/1000BASE-X ports, and combo ports that can operate as either copper or fiber. Additionally, optional optical sub-cards allow further expansion for enterprise network deployments, making the S3700 suitable for both access and aggregation layers in fiber-based networks .
