SFP-10G-LR-S (Cisco 10GBASE-LR S-Class SFP+ Transceiver Module, 10km, Single-Mode Fiber, LC, DOM, 1310nm)

SFP-10G-LR-S is a Cisco S-Class SFP+ optical transceiver for 10 Gigabit Ethernet interfaces on supported Cisco platforms. The module uses single-mode fiber as its optical signal medium rather than multimode cabling or direct attach copper. Its optical interface presents a Dual LC/PC connector for PC or UPC patch cord ends. The transmit and receive wavelength is 1310 nm for the standards-based 10GBASE-LR optical path. The maximum link distance is 10 km on standard single-mode glass under supported channel loss conditions. The operating temperature class is Commercial for conventional network equipment rooms and controlled rack environments. Digital optical monitoring is supported for real-time temperature, bias, voltage, and optical power telemetry. Hot-swappable input/output hardware supports service replacement, pay-as-populate port use, and installation without host shutdown. A blue bail latch, Cisco quality identification, and certified optic recognition support physical handling and platform validation workflows.

SFP-10G-LR-S carries 10GBASE-LR host signaling through an Ethernet SFP+ port. TX power range delivers -8.2 dBm to 0.5 dBm average optical output. RX sensitivity reaches -14.4 dBm minimum average receive power. Receiver overload point holds at 0.5 dBm maximum receive power. IEEE 802.3ae governs the LR optical interface and a 2 m minimum cabling distance. SFF-8472 provides two-wire diagnostic register access for monitored module parameters. With 1 W maximum draw, the module fits the SFP+ power envelope for LR optics. Average power figures apply across transmitter and receiver specifications rather than peak values. Optical parameters apply across operating temperature and end-of-life conditions during validated operation. Class 1 laser requirements align with IEC 60825-1 safety limits. The LR optical budget reaches 6.2 dB channel insertion loss. No FCoE support applies to the S-Class LR orderable module. Optical interoperability works with 10GBASE XENPAK, 10GBASE X2, and 10GBASE XFP interfaces on matching links.

Compatible platform families include Cisco Catalyst 2960-X, Catalyst 3850, Catalyst 4500-X, Nexus 3000, Nexus 9000, UCS 6200, and ASR 9000. Deployment roles span data centre interconnect, enterprise campus backbone, metro aggregation, edge handoff, and service provider transport. OS2 grade patch infrastructure matches the long-reach campus and aggregation paths buyers specify for this optic. Buy SFP-10G-LR-S from ORM Systems in new and certified refurbished condition.
