Keep critical network links stable with a 10-pack of AddOn SFP transceivers designed for Cisco GLC-LH-SMD compatibility. Built for single-mode fiber and LC connectivity, this module supports Gigabit Ethernet and 1000Base-LX network interfaces for long-reach optical networking in enterprise environments. The hot-swappable form factor simplifies maintenance windows and reduces disruption during upgrades or replacements. For infrastructure teams standardizing on TAA-compliant sourcing, this pack supports procurement requirements without forcing a redesign of the optical layer. It is a practical fit for data networking and optical network deployments where predictable interoperability matters more than generic commodity optics. Choose this model when you need a controlled, repeatable transceiver supply for branch uplinks, campus backbones, or replacement inventory. The 10-pack format helps reduce per-unit handling overhead and keeps spares aligned with operational demand.
