## Long description

The LevelOne 1.25Gbps Multi-mode SFP Transceiver is a high-performance fiber optic module designed to provide reliable full-duplex connectivity for Gigabit Ethernet networks. Operating at a wavelength of 850nm, this transceiver supports data transfer speeds of up to 1250 Mbit/s over distances reaching 550 meters. It adheres to the Multi-Source Agreement (MSA) standards, ensuring broad compatibility with various networking equipment, and utilizes a standard LC connector for secure integration into SFP ports.
Advantages
This transceiver offers a robust solution for high-speed data transmission, featuring a hot-pluggable design that allows for easy installation or replacement without powering down the network hardware. Its compliance with IEEE 802.3z standards guarantees seamless integration into existing Gigabit infrastructures. The compact form factor and efficient power consumption make it an ideal choice for optimizing space and energy usage in professional networking environments.
Suitable for
Distributed multiprocessing systems
Switch-to-switch and converter-to-switch connections
High-speed I/O file transfers
Bus extension applications
Data storage channel extension
When it may not be suitable
This module is specifically engineered for multi-mode fiber optic cabling and will not function with single-mode fiber infrastructure. Furthermore, it is limited to a maximum reach of 550 meters, making it unsuitable for long-range campus or wide-area network connections.
Key specifications
Data transfer rate: 1250 Mbit/s
Wavelength: 850nm
Maximum range: 550 meters
Connector type: Duplex LC
Power supply: 3.3V
Compliance: MSA and IEEE 802.3z
Laser safety: Class 1 (EN60825-1)
How to use
To install the transceiver, ensure your network switch or converter is powered on and supports SFP modules. Gently insert the transceiver into the SFP slot until it clicks into place. Connect your multi-mode fiber optic cable to the LC connector port. The device is hot-pluggable, meaning it will be automatically detected by the system once inserted, allowing for immediate data transmission without requiring a system reboot.
What to consider before purchase
Verify that your network hardware supports SFP (Mini-GBIC) modules
Ensure your cabling infrastructure is multi-mode fiber
Confirm that the required link distance does not exceed 550 meters
Usage recommendations
For optimal performance and longevity, avoid touching the optical fiber end-faces and keep the dust covers on the connectors whenever the module is not in use. Ensure the fiber cables are clean and free of debris before connection to maintain signal integrity.
