Módulo transceptor SFP BlueOptics SFP-BXU34-20KM-EE-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-20KM-EE-BO is a single-mode fiber SFP transceiver module designed for 1000BASE-BX-U applications with a maximum data rate of 1250 Mbit/s. It uses an LC simplex connector and supports one-fiber bi-directional transmission with a transmitter wavelength around 1490 nm and a receiver wavelength around 1310 nm. The transceiver is housed in metal, has a compact SFP form factor, and a stated mean time between failures (MTBF) of 1,000,000 hours, making it suitable for long-term deployment in network equipment that follows MSA SFP mechanical and electrical standards.

Advantages

The module provides 1.25 Gbit/s Ethernet-compatible signaling over single-mode fiber to distances up to 20 km and includes Digital Diagnostics Monitoring (DDM/DOM) capability for real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature when supported by host hardware. Manufactured to MSA guidelines and using high-quality components, the transceiver offers consistent interoperability with MSA-compliant SFP ports and reliable long-term operation with a low weight and metal housing for mechanical stability.

Key specifications

How to use

Insert the SFP transceiver into an MSA-compliant SFP slot on a switch, router or other network device while the host device is powered according to the vendor’s hot-plug guidelines. Connect an appropriate single-mode LC simplex fiber patch cord to the transceiver’s port, ensuring correct polarity and that the opposite end connects to a compatible BX transceiver (one side configured for 1310 nm receive / 1490 nm transmit and the other for the complementary directions). Verify link status and, if available, check DDM/DOM parameters via the host management interface to monitor module health and optical levels.

Recommendations

Use single-mode LC simplex patch cords and ensure the remote transceiver supports the 1000BASE-BX-U wavelength pairing. Confirm host device compatibility with third-party SFP modules and enable DDM/DOM support on the switch or router for live diagnostics. Protect connectors from dust and damage when not in use and perform end-face cleaning before making connections to maintain optimal optical performance.
