LevelOne 1,25 Gbit/s Singlemode priemyselný SFP transceiver, 10 km, 1310 nm, -40 °C až 85 °C

The LevelOne SFP-4210 is a single-mode industrial SFP transceiver that supports 1.25Gbps data rate over distances up to 10 km at a 1310 nm wavelength. Designed for industrial environments, it operates across a wide temperature range from -40°C to 85°C and is compliant with the SFP MSA and IEEE 802.3z Gigabit Ethernet standards. The module is hot-pluggable, RoHS-compliant and uses a duplex LC connector for full-duplex fiber connections.

Advantages

The transceiver provides a duplex LC connector and meets IEEE 802.3z Gigabit Ethernet requirements while operating from a single 3.3V power supply. Its industrial temperature rating ensures stable performance in harsh environments and the hot-swappable SFP form factor allows easy installation and replacement without powering down equipment.

Suitable for

• Long-distance single-mode fiber links up to 10 km
• Industrial Ethernet networks with extended temperature requirements
• Network equipment requiring SFP hot-swappable transceivers (switches, routers, media converters)

How to use

Insert the LevelOne SFP-4210 module into an SFP port on a compatible switch, router or media converter until it clicks into place. Connect a single-mode fiber cable with duplex LC connectors to the transceiver, ensuring correct Tx/Rx orientation. The module is hot-swappable; it can be inserted or removed while the host device is powered on. Verify link and appropriate speed settings on the host device after installation.

Recommendations

Use high-quality single-mode fiber and LC connectors, maintain proper bend radius and clean connector end-faces before installation. Confirm compatibility with the host device's SFP compatibility list and ensure firmware or configuration supports 1.25Gbps operation.
