SFP Transceiver BlueOptics SFP-1G-SX-ER-BO 1250 Mbit/s 850 nm Silver

The BlueOptics SFP-1G-SX-ER-BO is a compact fiber optic SFP transceiver module designed for 1000Base-SX applications. It supports a maximum data transfer rate of 1250 Mbit/s over multimode fiber using an 850 nm wavelength. Housed in a metal casing with an LC duplex connector, the module operates from a 3.3 V supply and weighs approximately 3 g, providing a standardized small form-factor pluggable solution for switches, routers and other network devices that accept SFP modules.

Advantages

This SFP transceiver follows MSA standards and is compatible with equipment that supports 1000Base-SX SFP modules. The metal housing provides mechanical robustness and EMI resilience typical for optical modules. With an 850 nm transmitter/receiver pair and LC duplex interface it enables simultaneous send/receive optical links over multimode fiber. The module’s low weight and standard SFP footprint make it easy to install and replace without special tools.

Suitable for

• Gigabit Ethernet links over multimode fiber
• Fiber connections between switches, routers and storage systems
• Short- to medium-distance optical links in data center and campus networks

Key specifications

• Interface: SFP (Small Form-Factor Pluggable) with LC duplex connector
• Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
• Wavelength: 850 nm
• Fiber type: multimode fiber (MMF)
• Supply voltage: 3.3 V
• Housing: metal
• Weight: approx. 3 g

How to use

Insert the SFP-1G-SX-ER-BO module into a compatible SFP port until it latches, then connect LC duplex multimode fiber patch cords to the transmit and receive ports. Ensure the host device supports the 1000Base-SX SFP form factor and, if required, enable any vendor-specific settings in the device’s firmware. Power the host device and verify link LEDs or management interfaces to confirm link establishment. Observe standard handling precautions for optical transceivers and fiber connectors to avoid contamination or damage.

Recommendations

Use high-quality multimode patch cords and, where possible, install fiber patch panels to maintain optimal link performance. If the host device supports digital diagnostics (DDM/DOM), monitor supply voltage, laser bias, output/input power and temperature to aid in troubleshooting and preventive maintenance.
