SFP transceiver module BlueOptics GLC-SX-MM-LEG-BO 1250 Mbit/s 850 nm

The BlueOptics GLC-SX-MM-LEG-BO is a fiber optic SFP transceiver module designed for 1000Base-SX applications. It supports a maximum data transfer rate of 1250 Mbit/s and operates at a wavelength of 850 nm, transmitting and receiving optical signals over multimode fiber. The module follows MSA SFP form-factor conventions and has a lightweight silver housing weighing approximately 20 g, making it suitable for use in compatible networking hardware that accepts SFP pluggable modules.

Advantages

This SFP transceiver provides standardized electrical and mechanical compatibility with SFP interfaces and supports multi-mode fiber links at short-range distances typical for 1000Base-SX deployments. Its silver metal housing is compact and lightweight for simple installation and handling. The module is designed for interoperability with equipment that supports 1000Base-SX SFP transceivers and offers a single-fiber transmit and receive pair via an LC duplex interface when used with appropriate fiber patch cords.

Suitable for

• Connecting switches and routers with SFP ports in LAN environments
• Short-range multimode fiber links in data center and campus networks
• Integrating into storage and network equipment that supports 1000Base-SX SFP modules

How to use

Install the BlueOptics SFP transceiver by inserting it into a compatible SFP slot on the network device until it clicks into place. Connect an LC duplex multimode fiber patch cable to the module’s connector, ensuring correct TX/RX alignment with the remote transceiver. Configure the network device as required for 1000Base-SX operation and verify link status through the device interface or diagnostic LEDs. If the host supports digital diagnostics (DDM/DOM), enable or read the monitoring data according to the device’s management interface.

Recommendations

For optimal performance, use quality multimode fiber patch cords and maintain proper connector cleanliness. Ensure the host equipment supports 1000Base-SX SFP modules and, if DDM/DOM is required, confirm that the device exposes diagnostic data. Follow standard ESD precautions when handling the transceiver and store it in protective packaging when not installed.
