SFP transceiver module BlueOptics SFP-500M-FNSR-BO 1250 Mbit/s 850 nm

The BlueOptics SFP-500M-FNSR-BO is a small form-factor pluggable (SFP) fiber optic transceiver module designed for 1.25 Gbit/s class links. It operates at an 850 nm wavelength, uses a duplex LC connector for multimode fiber, and provides a compact metal housing with a nominal 3.3 V supply and a lightweight design of approximately 3 g. The module is compatible with standard SFP interfaces and is intended for reliable short-reach optical connectivity in switches, routers and other networking equipment that support 1000Base-SX modules.

Advantages

The transceiver combines a standardized SFP interface with optical transmission at 850 nm, enabling interoperability with devices that follow the SFP MSA/1000Base-SX profile. A metal housing offers mechanical durability and thermal stability in rack and chassis installations. Low weight and SFP hot-pluggable form factor simplify installation and replacement. The module’s design targets multimode fiber links, providing up to typical short-reach distances defined by multimode fiber standards while keeping power requirements limited to a 3.3 V input.

How to use

Power down or follow hot-swap procedures recommended by your hardware vendor, then insert the SFP module into an SFP port until it seats securely. Connect LC duplex multimode fiber patch cords to the transmitter and receiver ports, ensuring correct polarity. Verify link status via the host device LED indicators or management interface. If the host supports digital diagnostics (DDM/DOM), enable or query the interface to monitor parameters such as supply voltage, optical power and temperature where supported by the system.

Recommendations

Use multimode fiber patch cords and appropriate fiber ratings (OM1/OM2/OM3/OM4) to achieve expected short-reach distances; maintain clean fiber endfaces and follow manufacturer guidance for hot-plugging and ESD protection. Confirm compatibility with the target device firmware or vendor compatibility lists before deployment to ensure full functionality.
