Glasvezel-transceivermodule BlueOptics QFX-SFP-1GE-SX-BO LC SFP

The BlueOptics QFX-SFP-1GE-SX-BO LC SFP is a fiber optic transceiver module designed for 1 Gigabit Ethernet over multimode fiber. It implements the 1000Base-SX standard with an LC duplex connector and operates at 850 nm for both transmitter and receiver. Housed in a lightweight aluminium casing (approx. 20 g), this SFP module follows MSA form-factor and electrical specifications and is intended for use in compatible networking equipment that supports 1000Base-SX SFP transceivers.

Advantages

This module provides standard-compliant optical transmission up to the multimode distance specified for 1000Base-SX, with simultaneous send and receive capability via the LC duplex interface. The aluminium housing offers mechanical robustness and thermal dissipation while keeping the module lightweight. Digital diagnostics (DDM/DOM) support enables monitoring of supply voltage, laser bias current, optical output and receive power, and temperature when the host hardware supports these features.

How to use

Insert the BlueOptics QFX-SFP-1GE-SX-BO into a compatible SFP slot of your switch, router or storage device while the host device is powered according to the manufacturer’s guidelines. Connect LC duplex multimode fiber patch cords to the module ensuring correct transmit/receive alignment. Verify link status on the host device and enable or check DDM/DOM readings through the host management interface if available. Follow standard electrostatic discharge (ESD) precautions when handling the module and avoid touching optical interfaces to prevent contamination.

Recommendations

Use high-quality OM1/OM2/OM3/OM4 multimode fiber and appropriate LC duplex patch cords to achieve optimal range and signal integrity. Ensure the host device explicitly supports 1000Base-SX SFP transceivers and DDM/DOM functionality if diagnostics are required. Clean connectors before mating and store unused transceivers with protective caps to maintain performance over time.
