SFP Transceiver BlueOptics SFP-GD-BX34-BO 1250 Mbit/s Silver

The BlueOptics SFP-GD-BX34-BO is a single‑mode fiber SFP transceiver designed for 1000BASE‑BX‑U applications. It supports a maximum data transfer rate of 1250 Mbit/s, operates from a 3.3 V supply and comes in a compact metal housing with a lightweight silver casing. The module uses an LC simplex connector and implements separate wavelengths for transmit and receive to enable bidirectional optical links over a single fiber, suitable for links up to approximately 20 km when used with appropriate single‑mode fiber.

Advantages

This SFP transceiver follows MSA standards and is compatible with MRV SFP‑GD‑BX34 platforms, enabling drop‑in replacement where the host device supports the original module. The metal housing provides mechanical durability and thermal stability while keeping the module weight low. The design supports Digital Diagnostics Monitoring (DDM/DOM) for real‑time monitoring of supply voltage, laser bias current, transmit power, received power and temperature when the host hardware supports these features. Components are selected for long service life and stable optical performance.

Suitable for

• Gigabit Ethernet links over single‑mode fiber using 1000BASE‑BX‑U
• Long‑reach point‑to‑point connections up to ~20 km
• Use in switches, routers, storage systems and other networking hardware that accept MSA SFP modules
• Environments requiring DDM/DOM monitoring for remote diagnostics

Key specifications

• Form factor: SFP (Small Form‑Factor Pluggable)
• Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
• Optical type: single‑mode fiber, bidirectional (BX) with separate TX/RX wavelengths
• Connector: LC simplex
• Operating voltage: 3.3 V
• Housing: metal, silver color
• Weight: 3 g
• Diagnostic: Digital Diagnostics Monitoring (DDM/DOM) compliant with MSA SFF‑8472 (if supported by host)

How to use

Insert the SFP transceiver into a compatible SFP port on the host device following the manufacturer's hot‑plug instructions. Connect an LC simplex single‑mode patch cable between transceivers at both ends of the link, ensuring correct orientation for TX and RX wavelengths. Power the host device and verify link status through device LEDs or management interfaces. If the platform supports DDM/DOM, enable or query diagnostic parameters to monitor optical power, bias current, supply voltage and temperature for ongoing link health checks.

Recommendations

For reliable performance, use single‑mode fiber and LC simplex patch cords rated for the required distance, confirm host compatibility with MRV SFP‑GD‑BX34 firmware requirements, and enable DDM/DOM monitoring on supported equipment to simplify maintenance and troubleshooting.
