SFP transceiver module BlueOptics SFPGLX40B15-BO 1250 Mbit/s Fiber optic

The BlueOptics SFPGLX40B15-BO is an SFP fiber optic transceiver module designed for single-mode links with a maximum data transfer rate of 1250 Mbit/s. Housed in a compact silver module weighing 20 g, it uses an SFP interface and an LC simplex connector. The module supports 1000BASE-BX-D operation with separate transmitter and receiver wavelengths and is intended for high-speed network transport over extended distances.

Advantages

The transceiver follows MSA-compatible mechanical and electrical specifications, enabling interoperability with SFP ports on switches, routers and other network devices that support 1000BASE-BX-D. Its lightweight metal housing and LC simplex connector simplify installation and cabling. The design supports simultaneous transmit and receive operation on single-mode fiber, and the module is suitable for continuous operation in networking environments requiring stable 1.25 Gbit/s links.

Suitable for

• Single-mode fiber connections between switches and routers
• Long-reach Ethernet links up to tens of kilometers
• Data center uplinks and edge aggregation
• Storage network and SAN interconnects supporting 1.25 Gbit/s

Key specifications

• Interface type: SFP (Small Form-factor Pluggable)
• Maximum data rate: 1250 Mbit/s (1.25 Gbit/s)
• Fiber type: Single-mode fiber (SMF)
• Connector: LC simplex
• Typical transmit/receive wavelength pair for BX-D operation (separate TX and RX wavelengths)
• Module colour: Silver
• Weight: 0.02 kg

How to use

Install the BlueOptics SFPGLX40B15-BO into an empty SFP slot of a switch, router or other compatible network device while the host device is powered down or following hot-swap procedures recommended by the device vendor. Connect an LC simplex single-mode patch cord to the module and to the remote transceiver or patch panel, observing correct TX-to-RX orientation for BX-D links. Verify link negotiation and port settings on the host device to ensure the interface is operating at the intended 1.25 Gbit/s mode.

Recommendations

Ensure the host device supports 1000BASE-BX-D and, if required, Digital Diagnostics Monitoring (DDM/DOM) for real-time status. Use quality single-mode fiber and properly terminated LC connectors to achieve optimal range and signal performance. Avoid excessive bending of fiber cables and follow ESD-safe handling when inserting or removing the transceiver.
