Cisco SD-AR1K-SFP1GO2G XGS-PON/10G EPON OLT SFP | Enterprise Fiber — SD-AR1K-SFP1GO2G

Deliver high-density fiber access with a Cisco pluggable designed for XGS-PON and 10G EPON OLT deployments. This module supports access networks that need tight optical integration, predictable performance, and a clean upgrade path for broadband service expansion. Built for OLT-side use, it aligns with carrier and enterprise access architectures where subscriber growth depends on compact optics and disciplined platform compatibility. The EML-based design is suited to demanding optical environments that require stable transmission characteristics and dependable service delivery. For teams planning fiber rollouts, this module helps preserve chassis density while supporting advanced passive optical network architectures. It is a practical choice when the goal is to scale access services without adding unnecessary complexity at the edge. Choose this Cisco pluggable when the deployment calls for a purpose-built optical component rather than a generic transceiver. It is intended for infrastructure teams that value compatibility, service assurance, and long-term network planning.
