Keep critical Gigabit links moving across single-mode fiber with this AddOn compatible 1000BASE-LX SFP transceiver. Built for IBM 90Y9424 environments and TAA-compliant procurement requirements, it gives infrastructure teams a clean path to replace or expand optical ports without changing the surrounding network design. The 1310 nm LX optical profile is suited to longer-reach fiber runs than short-range multimode optics, making it a practical fit for inter-building links, campus aggregation, and distribution-layer uplinks. LC duplex connectivity aligns with standard enterprise fiber plant practices, while the SFP form factor supports straightforward deployment in compatible switches, routers, and media platforms. For teams managing mixed-vendor estates, this module helps preserve uptime and simplify sourcing. It is a focused, single-purpose transceiver: no excess features, no unnecessary complexity, just the optical interface needed to keep production traffic on the wire. When the cost of a failed link is measured in service interruptions, the value is in a part that fits correctly, performs predictably, and clears compliance review.
