Support legacy Fast Ethernet fiber links with a compact SFP designed for practical network maintenance. This 100Base-LX module uses optical fiber media and an LC duplex interface to deliver 100 Mbps connectivity for access-layer deployments, departmental workgroups, and other short-distance network segments. For infrastructure teams, the value is not just speed — it is continuity. This TAA-compliant module helps preserve existing Cisco-compatible environments without forcing a broader hardware change. It is a straightforward replacement option when you need to keep fiber-connected endpoints online, maintain spare-part consistency, and avoid unnecessary migration costs. The 1-port SFP design fits standard transceiver slots and aligns with common enterprise procurement requirements. With a 3-year warranty, it offers a stronger ownership profile than low-cost alternatives that may save money up front but create risk later. Choose it when uptime, compatibility, and predictable lifecycle support matter more than headline specs.
