Product information

Description

LevelOne SFP-3111 is a multi-mode SFP transceiver designed for Gigabit Ethernet and fiber network links. It supports a bi-directional data rate of up to 1.25 Gbps over a single duplex fiber core and is intended for use with 50/62.5 μm multi-mode fiber, providing reach up to 2 km. The module uses a 1310 nm FP LD light source, features a duplex LC connector and operates from a single +3.3 V power supply. It is built to comply with relevant IEEE and ANSI specifications and meets EN 60825-1 laser safety requirements.

Advantages

The transceiver offers a compact SFP form factor that enables flexible deployment in compatible switches and routers without additional configuration. It provides standardized electrical and optical interfaces for straightforward integration, low power operation at 3.3 V, and compliance with industry agreements (MSA) and safety standards. Its design supports reliable Gigabit Ethernet links over multi-mode fiber up to 2 km.

Suitable for

  • Gigabit Ethernet uplinks and links within campus or enterprise networks
  • Short-range fiber connections in data centers and wiring closets
  • Fiber channel applications and equipment requiring MSA-compliant SFP modules

Key specifications

  • Wavelength: 1310 nm
  • Optical source: FP laser diode
  • Maximum data rate: 1.25 Gbps (NRZ)
  • Fiber type: Multi-mode (50/62.5 μm)
  • Maximum reach: up to 2 km
  • Connector: Duplex LC
  • Power supply: +3.3 V
  • Form factor: SFP (Small Form-Factor Pluggable)
  • Standards: IEEE 802.3z compatible
  • Safety: Designed to meet EN 60825-1 (Class 1 laser)

How to use

Insert the SFP transceiver into a compatible SFP slot on a switch, router or media converter until it latches, then connect duplex LC multi-mode fiber cables (50/62.5 μm) to the module. Ensure the connected device is powered and configured for Gigabit Ethernet operation at 1.25 Gbps as required; no additional software is needed for the module itself. Observe proper fiber handling and connector cleanliness to maintain link quality.

Usage recommendations

Use this module with multi-mode fiber of the specified core sizes and keep link distances within the 2 km limit. Clean LC connectors before insertion, avoid excessive bending of fiber cables, and verify module compatibility with your network equipment's SFP slot and supported standards.
