SFP transceiver module BlueOptics SFP-GD-BD35-BO 1250 Mbit/s Fiber optic

The BlueOptics SFP-GD-BD35-BO is a single‑port SFP fiber optic transceiver module designed for up to 1250 Mbit/s data transfer over single‑mode fiber. The module has a metal housing, a compact form factor and operates from a 3.3 V input, making it compatible with standard SFP slots in switches, routers and other network equipment. It implements a 1000BASE-BX-U link with LC simplex connector and supports long-range links up to tens of kilometers when used with appropriate single‑mode cabling.

Advantages

The transceiver offers a combination of compact SFP form factor, metal housing for mechanical robustness and a low weight of approximately 3 g. It supports established 1000BASE-BX-U optics with separate transmit and receive wavelengths for single‑mode fiber, enabling duplex communication over a single strand. Built to MSA-compatible mechanical and electrical standards, the module is suitable for straightforward integration into equipment that supports standard SFP optics and provides optional digital diagnostics (DDM/DOM) for real‑time monitoring of supply voltage, laser bias current, optical output and input power, and temperature.

Suitable for

• Upgrading or expanding ethernet connections in switches and routers
• Long‑reach single‑mode fiber links for enterprise and carrier networks
• Interconnecting storage systems and network appliances that accept SFP modules
• Replacement of compatible 1000BASE-BX-U transceivers in supported hardware

Key specifications

• Interface type: SFP (small form‑factor pluggable)
• Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
• Connector: LC simplex
• Optical type: single‑mode fiber, 1000BASE-BX-U (separate Tx/Rx wavelengths)
• Supply voltage: 3.3 V operating input
• Housing: metal
• Weight: approx. 0.003 kg
• Reach: designed for long‑distance links (tens of kilometers depending on fiber and link budget)
• Digital diagnostics: DDM/DOM support (if supported by host hardware)

How to use

Install the BlueOptics SFP-GD-BD35-BO by inserting it into a compatible SFP slot on your network device until it latches. Connect an LC simplex single‑mode patch cord to the module and to the remote transceiver or patch panel, observing correct Tx/Rx orientation for the 1000BASE-BX-U single‑fiber operation. Ensure the host device supports the 1000BASE-BX-U protocol and, if you plan to use digital diagnostics, confirm the platform provides DDM/DOM access. Configure the network interface on your device according to your network settings and verify link status through the host management interface.

Recommendations

Use single‑mode fiber with appropriate attenuation and link budget for long‑distance connections and pair the transceiver with compatible BlueOptics fiber patch cords or MSA‑compliant cabling. Verify DDM/DOM support on the host to access real‑time diagnostics, and follow standard ESD handling procedures when inserting or removing the SFP module to avoid damage.
