## Long description

The LevelOne 2.5Gbps Single-mode SFP Transceiver is a high-performance fiber optic module engineered for reliable long-distance data transmission. Designed to support data rates of up to 2.5 Gbps, this module facilitates efficient network connectivity over single-mode fiber infrastructure. It operates at a 1550nm wavelength and is capable of maintaining stable connections over distances of up to 40km, making it a robust solution for demanding networking environments.
Advantages
This transceiver offers significant benefits for network administrators looking to extend their infrastructure. Its hot-swappable design allows for easy installation or replacement without interrupting network operations. The inclusion of Digital Diagnostics Monitoring (DDM) provides real-time status updates, enabling proactive maintenance and troubleshooting. Furthermore, the module is built to operate within an extended commercial temperature range, ensuring consistent performance in varying environmental conditions while maintaining low power consumption.
Suitable for
Long-distance network backbone connections
Upgrading existing Gigabit Ethernet infrastructure
Enterprise-level fiber optic data transmission
Data center interconnections
This transceiver is not suitable for use with multi-mode fiber optic cabling, as it is specifically designed for single-mode applications. Additionally, it may not be compatible with network hardware that does not adhere to standard SFP Multi-Sourcing Agreement (MSA) specifications.
Key specifications
Data transfer rate: 2500 Mbit/s
Wavelength: 1550nm
Maximum distance: 40km
Connector type: Duplex LC
Power consumption: 1 W
Operating temperature: -10℃ to 85℃
Form factor: SFP
How to use
To install the transceiver, ensure your network device is powered on or off according to the manufacturer's guidelines for hot-swappable components. Insert the module into an available SFP slot until it clicks securely into place. Connect your single-mode fiber optic cable with a duplex LC connector to the transceiver port. Once connected, the device should be automatically detected by your network hardware, allowing you to monitor its status through the DDM interface.
What to consider before purchase
Verify that your network switch or router supports 2.5Gbps SFP modules.
Ensure you are using compatible single-mode fiber optic cabling.
Check that your existing infrastructure supports the 1550nm wavelength requirement.
Confirm that the device is compatible with the SFP MSA standard.
Usage recommendations: Always handle the fiber optic connectors with care and keep them clean to prevent signal loss. Ensure the module is fully seated in the SFP port to maintain a stable electrical connection.
