Modulo transceiver SFP BlueOptics SFP-GD-BD34-BO 1250 Mbit/s

The BlueOptics SFP-GD-BD34-BO is a fiber optic SFP transceiver module designed for single-mode optical links with a maximum data transfer rate of 1250 Mbit/s. Housed in a silver metal casing and weighing approximately 3 g, the module operates at a 3.3 V input and uses an LC simplex connector to send and receive signals over single-mode fiber. The transceiver follows MSA SFP form-factor standards and is compatible with systems that accept MRV SFP-GD-BD34 compatible 1000BASE-BX-U modules.

Advantages

The module provides a compact SFP interface for straightforward hot-pluggable deployment in switches, routers and similar networking equipment. Its metal housing offers mechanical robustness and heat dissipation while the single-mode optical design supports long-reach links. Digital diagnostics (DDM/DOM) support enables remote monitoring of supply voltage, laser bias current, output and input power as well as module temperature when the host hardware supports these features.

Suitable for

• Single-mode fiber Ethernet links up to 1.25 Gbit/s
• Replacement or expansion of SFP slots in switches and routers
• Long-distance point-to-point optical connections (operator- or data-center links)
• Environments requiring digital diagnostics for link monitoring

Key specifications

• Interface type: SFP (MSA compliant)
• Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
• Connector: LC simplex (single fiber transmit and receive)
• Fiber type: Single-mode optical fiber
• Housing: Silver metal casing
• Operating voltage: 3.3 V
• Weight: approx. 0.003 kg
• Digital diagnostics monitoring (DDM/DOM): supported when host hardware provides support

How to use

Insert the BlueOptics SFP-GD-BD34-BO into a compatible SFP slot on the powered-off or hot-swappable host device according to the host vendor's instructions, then connect an LC simplex single-mode patch cord to the module. Ensure the host system supports the required transmission protocol (1000BASE-BX-U) and, if DDM/DOM is required, that the host exposes the diagnostic interface. After insertion, verify link status and diagnostics through the host system's network management interface.

Recommendations

Use high-quality single-mode LC patch cords and, where possible, route fibers through patch panels to protect connectors. Verify compatibility with the target hardware and confirm that the link budget (wavelength, transmitter/receiver specification and fiber attenuation) is suitable for the desired distance. When monitoring link health, enable DDM/DOM features in the host to access real-time module parameters.
