Product information

Description

The LevelOne SFP-3211 is a single-mode SFP transceiver designed for Gigabit Ethernet and single-mode fiber links. It supports up to 1.25 Gbps bidirectional data transfer over a duplex LC-connected single 9 µm fiber and uses a 1310 nm FP laser diode. The module is compliant with IEEE 802.3z and MSA specifications and requires a single +3.3 V power supply.

Advantages

The transceiver provides a compact, MSA-compliant SFP form factor with AC/DC differential electrical interface and RoHS lead-free construction. It offers plug-and-play operation without additional configuration software and is designed for eye safety to meet LASER Class 1 (EN60825-1). The device combines standard Gigabit Ethernet compatibility with simple power requirements.

Suitable for

Gigabit Ethernet single-mode fiber links
Fiber Channel applications compatible with the stated data rates
Network equipment requiring SFP slots (switches, routers, media converters)

Key specifications

Model: LevelOne SFP-3211
Data rate: 1.25 Gbps (NRZ)
Wavelength: 1310 nm (FP laser diode)
Connector: Duplex LC
Fiber type: Single-mode (9 µm)
Power supply: +3.3 V
Form factor: SFP, MSA compliant

How to use

Insert the SFP-3211 module into a compatible SFP slot on your network device until it clicks into place. Connect a single-mode duplex LC fiber cable (9 µm) to the module, ensuring correct transmit/receive orientation. Power the host device with the standard +3.3 V supply already provided by the SFP slot; no additional configuration software is required. Verify link and data transmission using the host device status indicators or network management tools.

Usage recommendations

Install and remove the module with the host device powered down if the device documentation recommends hot-swap protection; keep fiber connectors clean and capped when not in use to maintain link quality and eye-safety compliance.
