SFP transceiver BlueOptics SFP-DGD-SX-BO 1250 Mbit/s 850 nm

The BlueOptics SFP-DGD-SX-BO is a small form-factor pluggable (SFP) fiber optic transceiver designed for 1000Base-SX networks. It supports a maximum data transfer rate of 1250 Mbit/s over multimode fiber using 850 nm wavelength. The module comes in a metal housing, operates at 3.3 V and weighs approximately 3 g. It uses an LC duplex connector and follows MSA standards, making it compatible with hardware platforms that accept standard 1000Base-SX SFP transceivers.

Advantages

The transceiver delivers gigabit-class performance with support for up to 1.25 Gbit/s and typical multimode reach. Its metal housing provides mechanical robustness and EMI shielding while the compact SFP form factor enables hot-plug installation in switches, routers and storage devices. The module is manufactured to MSA specifications and undergoes compatibility testing to ensure reliable operation in systems that support standard 1000Base-SX SFPs. Low weight and standard 3.3 V operation simplify deployment in many network devices.

Suitable for

• Fiber connections between switches and routers in enterprise LANs
• Server-to-switch uplinks and data center short-range links
• Storage systems and SANs requiring 1000Base-SX transceivers
• Replacement or expansion modules in MSA-compliant network equipment

Key specifications

• Interface type: SFP (Small Form-factor Pluggable)
• Wavelength: 850 nm (multimode fiber)
• Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
• Connector: LC duplex
• Power supply: 3.3 V operation
• Housing: Metal
• Typical reach: suitable for multimode fiber links (up to several hundred meters depending on fiber type and link budget)
• Weight: ~3 g

How to use

Insert the SFP transceiver into an SFP slot of a powered network device following the device manufacturer's hot-plug instructions. Connect LC duplex patch cords to the transmitter and receiver ends, observing correct transmit/receive orientation. Ensure the host device supports 1000Base-SX SFP modules and, if required, enable or verify digital diagnostic monitoring (DDM/DOM) support in the device firmware to read real-time operating parameters. Check link status and perform basic link tests after installation to confirm proper operation.

Usage recommendations

Use high-quality multimode fiber (OM3/OM4 where higher performance is required) and LC duplex patch cords to maximize link reliability. Verify that the target hardware supports 1000Base-SX SFP modules and DDM/DOM if digital diagnostics are needed. Avoid excessive bending and contamination of fiber connectors; clean connectors before mating and follow ESD precautions when handling the transceiver.
