SFP-transceivermodule BlueOptics SFP-1G-SX-VA-BO 1250 Mbit/s 850 nm

The BlueOptics SFP-1G-SX-VA-BO is a small form-factor pluggable (SFP) fiber optic transceiver module designed for 1.25 Gbps class networks. It supports transmission and reception at 850 nm over multimode fiber and uses an LC duplex connector. The module is housed in metal, operates from a 3.3 V supply and weighs approximately 3 g. It conforms to MSA form-factor standards and is compatible with devices that support 1000Base-SX SFP modules.

Advantages

The module offers standardized SFP form factor compatibility for easy hot-swap installation and wide vendor interoperability. Operation at 850 nm with LC duplex connection enables short- to mid-range multimode links up to typical multimode distances while maintaining a compact, low-weight metal housing for durability and EMI shielding. The transceiver supports digital diagnostics monitoring for online status information when the host hardware provides DDM/DOM support.

Suitable for

• 1 Gbps Ethernet links over multimode fiber (1000Base-SX)
• Inter-switch connections and uplinks in data centers and wiring closets
• Storage networking and SAN connectivity that support SFP modules
• Network equipment replacement or upgrades where Viavi-compatible 1000Base-SX SFP is required

Key specifications

• Interface type: SFP (LC duplex)
• Data rate: up to 1250 Mbit/s (1.25 Gbps)
• Wavelength: 850 nm (transmit and receive)
• Fiber type: multimode fiber (MMF)
• Connector: LC duplex
• Housing: metal
• Operating voltage: 3.3 V
• Weight: approx. 3 g

How to use

Install the BlueOptics SFP-1G-SX-VA-BO by powering down or using hot-swap capability if the host supports it, then insert the SFP into a compatible SFP slot until it latches. Connect LC duplex multimode fiber patch cords to the module’s transmit and receive ports, ensuring correct fiber polarity. Configure the host network interface for 1000Base-SX operation if required by the equipment. If the host supports DDM/DOM, enable monitoring to read real-time diagnostic parameters such as supply voltage, laser bias current, transmit power, receive power and temperature.

Recommendations

Use short-length OM3/OM4 multimode fiber and quality LC duplex patch cords for optimal reach and low loss. Verify compatibility with the switch, router or storage system vendor and ensure the host firmware/software supports third-party SFP modules and DDM/DOM if monitoring is required. Avoid excessive bending or stress on fiber cables and follow ESD precautions when handling the metal-bodied transceiver.
