Cisco RD-T-10G-LR 10Gbps Singlemode SFP+ Module | LR, Enterprise — RD-T-10G-LR

Build longer-reach 10 GbE links without changing the operational model of your network. Cisco RD-T-10G-LR delivers 10 Gbps connectivity over singlemode fiber in an SFP+ form factor, giving infrastructure teams a clean path for uplinks and backbone connections that need optical reach and predictable performance. This LR optic is a practical choice when copper cannot meet distance requirements or when fiber is already the standard across the site. The LC connector keeps integration familiar for enterprise fiber plant, while the SFP+ design supports dense switch environments and straightforward module replacement. For teams planning data center interconnects, aggregation uplinks, or campus backbone segments, singlemode LR optics help preserve headroom without overbuilding the link. Cisco’s enterprise optics are often selected when consistency, compatibility, and procurement discipline matter as much as raw speed. RD-T-10G-LR fits that profile: a focused 10 GbE optic for singlemode deployments where link reach and fiber infrastructure justify the investment. Ideal For Data center uplinks over singlemode fiber Inter-switch backbone links across longer distances Campus aggregation connections using optical cabling Network refresh projects that standardize on LC-based fiber infrastructure Why This Product 1 Designed for singlemode fiber rather than copper cabling 2 Supports longer-reach enterprise links in an SFP+ format 3 Uses LC connectivity for standard fiber plant integration 4 Fits uplink and backbone roles where optical reach is required
