Glasvezel-SFP-transceiver BlueOptics 3FE25772AA-BO 20000 m aluminium

The BlueOptics 3FE25772AA-BO fiber optic SFP transceiver is a single-port small form-factor pluggable module designed for 1000BASE-BX-U optical links over single-mode fiber. Housed in an aluminium casing and weighing approximately 20 g, this SFP supports data transmission up to 20,000 m using an LC simplex connector. It implements separate transmit and receive wavelengths to carry up to 1.25 Gbit/s and is compatible with major networking platforms that support the original Alcatel‑Lucent 3FE25772AA 1000BASE‑BX‑U SFP.

Advantages

The aluminium housing provides mechanical robustness and thermal stability while the SFP form factor ensures hot-pluggable installation in supported transceiver slots. Designed to meet MSA standards, this module delivers interoperable optical performance with LC simplex connectivity and distinct transmit/receive wavelengths for single‑fiber bi‑directional operation. Built with high-quality optical components and tested for compatibility with Alcatel‑Lucent platforms, the transceiver offers long service life and predictable behaviour in mixed-vendor environments.

Suitable for

• Point-to-point single-mode fiber links up to 20 km
• Ethernet and Fibre Channel over Ethernet (up to 1.25 Gbit/s)
• Integration into switches, routers and storage systems that accept SFP 1000BASE‑BX‑U modules
• Long-reach links where electromagnetic immunity is required

How to use

Insert the SFP transceiver into a compatible SFP slot while the host device is powered on or follow the equipment vendor's hot‑plug instructions. Connect an LC simplex single‑mode patch cord between this transceiver and a corresponding BX‑U transceiver at the remote end, ensuring proper orientation of transmit and receive channels for single-fiber bi‑directional operation. Configure the host port according to your network requirements and verify link status through the device management interface. If the host supports digital diagnostics (DDM/DOM), enable and monitor the available real‑time parameters such as optical power and temperature for proactive maintenance.

Recommendations

Use high-quality single-mode fiber patch cords and ensure the remote end uses a compatible BX‑U transceiver with matching wavelength pairing. Verify that the network device firmware supports third-party SFP modules and the DDM/DOM feature if remote monitoring is required. Keep optical connectors clean and use dust caps when modules are not connected to maintain signal integrity.
