Network switch module SonicWall 02-SSC-8390 2.5 Gigabit Ethernet 25 Gbit/s

The SonicWall 02-SSC-8390 is a 25 Gbit/s network switch module providing high-speed short-range optical connectivity. Designed to deliver multi-gigabit links, the module uses a 2.5 Gigabit-capable interface specification and operates at an 850 nm wavelength for multimode fiber applications, supporting reach commonly required within data centers and enterprise wiring closets.

Advantages

This module offers a compact optical form factor with support for 25 Gbit/s aggregated throughput and compatibility with multimode fiber at 850 nm. It enables lower-latency, high-bandwidth links for uplinks and server aggregation while keeping installation straightforward due to standard optical interface characteristics. The device is suitable for integration into SonicWall network environments where consistent performance and predictable short-range optical operation are required.

Suitable for

When it may not be suitable

This optical module is intended for short-range multimode fiber links at 850 nm and is not appropriate for single-mode long-reach connections. It also may not be suitable where copper-based Ethernet or lower-speed interfaces are required, or in networks that mandate different wavelengths or transceiver form factors.

Key specifications

How to use

Install the module into a compatible SonicWall or supported switch SFP28/25G-capable slot following the vendor's hot-swap and ESD guidelines. Attach multimode fiber patch cables using the appropriate LC-style connectors or the connector type supported by the host, ensure correct polarity, and verify link negotiation and speed on the switch interface. Confirm that the connected equipment is configured for 25 Gbit/s operation and monitor the link status and error counters after installation.

What to consider before purchase

Recommendations

Use this module for short-distance, high-bandwidth links within data centers and aggregation layers. Maintain clean fiber connectors, follow recommended insertion/removal procedures, and verify link parameters after installation to ensure reliable 25 Gbit/s operation.
