BlueOptics 1000Base-SX SFP network transceiver module 1250 Mbit/s 850 nm

The BlueOptics 1000Base-SX SFP network transceiver module is a compact fiber-optic SFP designed for Gigabit Ethernet and other 1.25 Gbps optical links. Operating at an 850 nm wavelength over multimode fiber, the module supports a maximum line rate of 1250 Mbit/s and comes in a lightweight silver housing. It is RoHS-compliant and designed for long operational lifetimes, making it suitable for use in switches, routers, storage platforms and other network devices that accept SFP modules.

Advantages

This SFP transceiver offers standardized SFP form-factor compatibility and an LC duplex optical interface for transmit and receive channels. It provides a proven multimode 850 nm optical solution for short- to medium-reach links with reliable performance and a long mean time between failures. The module supports industry-standard digital diagnostics (DDM/DOM) when the host device supports the feature, enabling real-time monitoring of key optical and electrical parameters.

Suitable for

• Gigabit Ethernet connections over multimode fiber
• Fibre Channel over Ethernet and SAN interconnects up to 1.25 Gbps
• Switch-to-switch, switch-to-server and switch-to-patch-panel links
• Short to mid-range campus and data center fiber runs

• Digital Diagnostics Monitoring (DDM/DOM) support (if supported by host)

How to use

Install the BlueOptics 1000Base-SX SFP by inserting it into an SFP slot on a compatible switch, router or network device while the device is powered down or as supported by the vendor hot-swap guidelines. Connect an LC duplex multimode fiber patch cable to the module’s LC connector, ensuring correct transmit/receive orientation. Configure the host interface for Gigabit Ethernet or the required protocol; if DDM/DOM monitoring is needed, enable or query the diagnostics via the host management interface. Follow device manufacturer instructions for any firmware or compatibility settings.

Recommendations

Use high-quality multimode fiber and properly matched LC patch cords to achieve optimal range and signal integrity. Confirm host device compatibility with SFP transceivers and, if required, validate DDM/DOM support to enable diagnostic monitoring. Avoid excessive mechanical stress on fiber connectors and follow electrostatic discharge (ESD) precautions when handling the module.
