Cisco SFP-10G-LR 10GBASE-LR SFP+ Module 10km SMF

Cisco SFP-10G-LR Transceiver

The Cisco SFP-10G-LR Module provides high-speed 10 Gigabit Ethernet connectivity for enterprise and data center networking environments. This transceiver operates on standard single-mode fiber (SMF) to achieve link lengths of up to 10 kilometers. It utilizes a 1310nm laser to ensure reliable data transmission over long distances. Consequently, network engineers often deploy this module for campus backbone links and metropolitan area networks. The SFP+ form factor allows for high-density port configurations on switches and routers. Therefore, it optimizes rack space while maintaining high throughput. This hardware complies with IEEE 802.3ae standards for 10GBASE-LR interfaces.

Key Features

• Hot-Swappable Design
  This module plugs into a Cisco Ethernet SFP+ port without requiring a system reboot or shutdown process.

• Digital Optical Monitoring
  Integrated DOM support allows real-time access to operating parameters such as laser power and temperature.

• 1310nm DFB Laser
  The internal Distributed Feedback laser provides a stable light source for long-reach optical transmission.

• Low Power Consumption
  The device typically consumes less than 1.0W of power to reduce thermal output in high-density racks.

The 10GBASE-LR standard defines a physical layer specification for 10 Gigabit Ethernet over serial single-mode fiber. This specific transceiver supports a nominal wavelength of 1310 nm and uses a dual LC/PC connector interface. Additionally, the device features a hot-swappable input/output design. This allows the module to plug into a Cisco Ethernet SFP+ port without shutting down the host system. Such capability minimizes network downtime during maintenance or upgrades. Furthermore, the module supports the Cisco quality identification (ID) feature. This enables a Cisco switch or router to identify and validate that the transceiver is a genuine Cisco product.
