Product information

Description

Lightwin LWO-SFP-85-SX is a 1.25 Gbit SFP fiber optic transceiver designed for multimode networks operating at 850 nm. It supports LC duplex connections and digital diagnostics (DDM), and is intended for short-range links such as enterprise networks, data centre interconnects and media converters requiring multimode operation up to 550 m. The module uses a single +3.3 V power supply and complies with laser safety and RoHS standards.

Advantages

The transceiver offers reliable short-range multimode performance with support for up to 550 m over 50/125 µm multimode fiber and an LC duplex interface for easy integration. Built-in digital diagnostics (SFF-8472) enables real-time monitoring of optical parameters, while LVPECL-compatible I/O, low EMI and ESD protection simplify system design and improve operational stability.

Suitable for

  • Short-range multimode uplinks in enterprise and campus networks
  • Data centre horizontal and equipment interconnects
  • Media converters and switches with SFP ports
  • Industrial networking applications that use multimode fiber

When it may not be suitable

This SFP is intended for multimode links at 850 nm and is not suitable for single-mode long-reach applications or wavelength-division multiplexing systems. It also requires compatible SFP ports and will not work in devices that do not support the SFP form factor or the LVPECL-compatible electrical interface.

Key specifications

  • Data rate: 1.25 Gbit/s (1250 Mbit/s)
  • Wavelength: 850 nm
  • Maximum link distance: up to 550 m on 50/125 µm multimode fiber
  • Connector: LC duplex
  • Power supply: +3.3 V
  • Optical components: VCSEL transmitter and PIN photodiode receiver
  • Diagnostics: Digital Diagnostic Monitoring (SFF-8472)
  • Input/Output interface: LVPECL-compatible
  • Standards and safety: IEC-60825 laser safety compliant; RoHS compatible

How to use

Insert the SFP transceiver into an available SFP port on a switch, media converter or similar device while the host equipment is powered off or following the host vendor's hot-swap procedure. Connect LC duplex multimode fiber patch cords to the module's LC connectors, observing correct TX/RX orientation. Enable or verify DDM monitoring on the host system if real-time optical parameter reporting is required. Ensure the connected fiber type and distance do not exceed the specified limits.

What to consider before purchase

  • Confirm the host device supports 1.25 Gbit SFP modules and the LVPECL-compatible interface
  • Verify you will use multimode 50/125 µm fiber and that link distances are within 550 m
  • Check that LC duplex connectors match your existing cabling
  • Confirm DDM support is required and supported by your equipment

Usage recommendations

Use the Lightwin LWO-SFP-85-SX in network segments where multimode 850 nm short-reach connectivity is needed; pair with quality 50/125 µm fiber and proper LC duplex patch cords, enable DDM for monitoring, and follow manufacturer guidance on hot-swap procedures and ESD precautions.
