The inclusion of DOM provides essential visibility into link health, helping to prevent downtime and optimize network performance.
Dual Fiber Support
Operates on both multimode and singlemode fiber, offering flexibility for short-range and long-haul applications without needing separate modules.
- MMF for distances up to 550 meters
- SMF for distances up to 10 kilometers
Monitoring Capabilities
DOM enables real-time monitoring of optical parameters, facilitating troubleshooting and ensuring stable network connections.
- Tracks optical power levels
- Monitors temperature and voltage
Deployment / Use Cases
This SFP transceiver is ideal for upgrading existing network infrastructure to Gigabit Ethernet over fiber, providing a reliable and high-speed backbone for data-intensive applications. It suits environments where signal integrity and distance are critical, such as connecting switches between buildings or extending network reach across large campuses.
Common use cases include enterprise network expansions, data center interconnects, and service provider networks requiring robust optical links. Its MSA compliance ensures broad compatibility with Cisco and other vendor equipment, making it a versatile choice for mixed-vendor environments. The refurbished condition makes it particularly valuable for budget-conscious projects without compromising on performance.
Physical Profile

FAQ
What is the difference between LX and LH in this SFP transceiver?
1000BASE-LX is the standard for Gigabit Ethernet over fiber, typically used for multimode fiber up to 550 meters. LH (Long Haul) extends this capability to singlemode fiber, supporting distances up to 10 kilometers. This transceiver supports both modes, making it versatile for short-range and long-distance applications without needing separate modules.
Does this SFP module support DOM, and what can it monitor?
Yes, this module includes DOM (Digital Optical Monitoring). It allows real-time tracking of key optical parameters such as transmit and receive optical power, temperature, and supply voltage. This monitoring helps network administrators detect issues like fiber degradation or connector problems early, enabling proactive maintenance and reducing downtime.
Is this transceiver compatible with non-Cisco equipment?
This transceiver is MSA (Multi-Source Agreement) compliant, which means it adheres to industry standards for form factor, electrical interface, and optical specifications. While it is a Cisco-branded module, MSA compliance generally ensures compatibility with a wide range of network equipment from other vendors that support standard SFP slots, but always verify with your specific device's compatibility list.
What types of fiber optic cable can I use with this SFP?
This transceiver supports both multimode fiber (MMF) and singlemode fiber (SMF). For multimode, use 50/125μm or 62.5/125μm fiber for distances up to 550 meters. For singlemode, use 9/125μm fiber for distances up to 10 kilometers. Ensure the fiber has LC/PC connectors to match the module's interface for optimal performance.
