Product information

Description

LevelOne SFP-3611 is a single-mode SFP transceiver designed for long-distance fiber links. It supports Gigabit Ethernet data rates up to 1.25 Gbps over a single duplex fiber core, uses a 1550 nm DFB laser diode light source, and fits standard SFP ports with a duplex LC connector. The module is optimized for 9 µm single-mode fiber and can reach distances up to 80 km while operating from a single +3.3 V power supply and meeting relevant industry standards.

Advantages

The transceiver offers cost-effective long-reach connectivity with small form-factor pluggable compatibility, low power operation at +3.3 V, and compliance with IEEE 802.3z and MSA specifications. It uses a DFB laser for stable 1550 nm transmission, provides a clear AC-coupled differential electrical interface, and meets RoHS and EN 60825-1 (Laser Class 1) safety requirements.

Suitable for

  • Long-distance Gigabit Ethernet links up to 80 km over single-mode fiber
  • WAN/metro fiber connections requiring 1550 nm transmission
  • Network equipment with SFP ports (switches, routers, media converters)

Key specifications

  • Data rate: 1.25 Gbps (NRZ)
  • Wavelength: 1550 nm (DFB laser diode)
  • Maximum reach: up to 80 km on 9 µm single-mode fiber
  • Interface: SFP with duplex LC connector
  • Power supply: single +3.3 V
  • Standards: IEEE 802.3z, MSA compliant; EN 60825-1 (Laser Class 1); RoHS

How to use

Insert the SFP-3611 module into any compatible SFP slot on your network device until it clicks into place. Connect a duplex LC single-mode fiber cable (9 µm) and ensure proper Tx/Rx orientation. Power the host device with the standard supply; the transceiver requires no additional configuration or installation software. Monitor link status via the host device to confirm operational 1.25 Gbps connectivity.

Usage recommendations

Use single-mode 9 µm fiber with appropriate attenuation characteristics for 80 km links, verify LC connector cleanliness before mating, and follow your equipment vendor’s guidelines for SFP compatibility and eye-safety procedures per EN 60825-1.
