It operates at a 1310 nm wavelength and is capable of achieving distances up to 10 kilometers. The SFP-10G-LR is a versatile, reliable, and cost-effective solution ideal for high-speed network connections in enterprise and data center environments, as well as telecommunications and service provider networks.

Detailed Description:

Model: SFP-10G-LR

• Form Factor: SFP+ (Small Form-factor Pluggable)
  • The SFP+ transceiver is an enhanced version of the standard SFP, designed to support higher speeds, specifically 10Gbps for 10 Gigabit Ethernet applications. Its compact size and hot-swappable nature allow it to be easily installed, removed, or replaced without interrupting network operations, providing flexibility and simplicity for network administrators.

Data Rate:

• 10 Gbps (10 Gigabit Ethernet): The SFP-10G-LR supports 10 Gigabit Ethernet speeds, enabling high-bandwidth communication for modern networks that require fast, reliable data transfer. This high-speed transmission is suitable for applications such as data center interconnects, network backbones, and high-performance computing environments.

Wavelength:

• 1310 nm: The SFP-10G-LR operates at the 1310 nm wavelength, which is well-suited for long-distance communication over single-mode fiber. The 1310 nm wavelength offers lower attenuation over long distances compared to shorter wavelengths like 850 nm, making it ideal for transmissions up to 10 kilometers.

Range:

• The SFP-10G-LR is designed for long-range communication over single-mode fiber (SMF):
  • Up to 10 km reach on single-mode fiber. This distance makes it suitable for connecting remote buildings, across campuses, or in metro-area networks where long-distance connections are needed.
  • The 10 km reach makes the transceiver ideal for high-speed connections that span long distances, such as between data centers, enterprise networks, and service provider environments.

Connector Type:

• The SFP-10G-LR uses an LC duplex connector, a compact and efficient connector type for fiber optic cables. The LC duplex connector ensures high-performance, reliable connectivity for both send and receive signals in a single cable, making it an optimal choice for high-density deployments and long-distance fiber optic links.

Compatibility:

• The SFP-10G-LR is compatible with a wide range of Cisco networking equipment that supports SFP+ modules, including Catalyst, Nexus, and ASR series switches, routers, and other devices. It integrates seamlessly with Cisco’s IOS and NX-OS operating systems, ensuring reliable, high-performance network connectivity.

Power Consumption:

• The SFP-10G-LR is designed to be energy-efficient, typically consuming less than 1W of power, which helps to minimize the overall energy footprint in large-scale deployments. This power efficiency is important for reducing operational costs in high-density network environments.

Hot-swappable:

• Like most SFP+ modules, the SFP-10G-LR is hot-swappable, meaning it can be inserted or removed from the network device without needing to power down the equipment. This feature ensures minimal disruption during installation, upgrades, or maintenance, making it a highly flexible and user-friendly solution.

Cisco Digital Optical Monitoring (DOM):

• The SFP-10G-LR supports Cisco’s Digital Optical Monitoring (DOM) technology, which allows real-time monitoring of critical optical parameters such as optical power, temperature, and voltage. This monitoring capability helps network administrators track the health and performance of the transceiver, troubleshoot potential issues, and ensure network stability.

Applications:

• Data Centers: Facilitates high-speed, long-distance connections between data center racks or between data centers located in different geographic locations.
• Enterprise Networks: Provides reliable, high-speed connections over longer distances between remote office locations, campus networks, or corporate headquarters.
• Telecommunications: Used by service providers to offer high-speed Internet access, private leased line services, and other long-distance communication needs.
• Metro Area Networks: Ideal for linking regional or metro area network infrastructure, enabling efficient and high-capacity fiber optic links between cities or locations.
• Network Backbone: Provides robust, long-range connectivity for the core network backbone in large-scale enterprise or service provider networks.

Key Features Summary:

• Data Rate: 10 Gbps (10 Gigabit Ethernet)
• Wavelength: 1310 nm for long-distance single-mode fiber communication
• Range: Up to 10 km on single-mode fiber
• Connector: LC duplex for single-mode fiber
• Power Consumption: Low, typically under 1W
• Hot-swappable: Can be installed or replaced without system downtime
• DOM Support: Real-time monitoring of optical power, temperature, and voltage
• Application: Ideal for data centers, enterprise networks, metro area networks, and telecommunications.

Conclusion:

The SFP-10G-LR is a powerful and versatile 10 Gigabit Ethernet transceiver module designed for long-distancecommunication over single-mode fiber. With a reach of up to 10 km, it is an ideal solution for high-speed, long-range connectivity in data centers, enterprise networks, and service provider environments. The module’s low power consumption, hot-swappable design, and support for Cisco’s Digital Optical Monitoring (DOM) make it a reliable and efficient choice for high-performance network deployments.
