## Summary description

The BlueOptics SFP-BXU34-40KM-SO-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. It features a metal housing, weighs 20 g, and has an MTBF of 1,000,000 hours, making it a reliable choice for network applications.

## Long description

The BlueOptics SFP-BXU34-40KM-SO-BO is a single-mode fiber optic SFP transceiver module designed for point-to-point links up to 40 km. It supports a maximum data transfer rate of 1250 Mbit/s (1000BASE-BX-U) and uses an LC simplex connector for single-fiber bidirectional transmission. The transceiver comes in a metal housing, has a compact SFP form factor, weighs approximately 20 g and is intended for use in network equipment that supports standard MSA-compliant SFP modules.
Advantages
This BlueOptics transceiver provides MSA-compliant electrical and mechanical compatibility with SFP ports and supports Digital Diagnostics Monitoring (DDM/DOM) when the host hardware enables it. The metal housing contributes to mechanical durability and heat dissipation, while the module’s specifications and component selection are intended to deliver long Mean Time Between Failures (MTBF) for stable operation in production networks. Its single-mode 1310 nm/1490 nm wavelength pairing and LC simplex interface allow use in long-reach fiber links with minimal susceptibility to electromagnetic interference.
Suitable for
Fiber links between switches, routers and aggregation devices up to 40 km
Single-mode backbone and campus network connections
Storage and server connectivity requiring 1.25 Gbit/s optical ports
Environments needing DDM/DOM monitoring support for optical diagnostics
Key specifications
Interface type: SFP (MSA-compliant)
Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
Optical mode: single-mode fiber
Wavelengths: transmit/receive pair suitable for 1000BASE-BX-U (typical 1490 nm TX / 1310 nm RX)
Connector: LC simplex
Maximum reach: up to 40 km (single-mode, depending on fiber and link budget)
Housing: metal SFP enclosure
Weight: approx. 0.02 kg
DDM/DOM: supported when enabled by host hardware
How to use
Install the SFP transceiver into an MSA-compliant SFP slot of a switch, router or other networking device while the device is powered according to the host manufacturer’s instructions. Connect a single-mode LC simplex fiber patch cable between transceivers at each link end, observing polarity for bidirectional single-fiber operation. Verify link parameters and enable DDM/DOM in the host system if optical diagnostics are required. Follow standard safety and handling procedures for optical modules to avoid ESD damage and protect fiber ends from contamination.
Usage recommendations
Use matched single-mode patch cords and ensure the link budget (attenuation and connectors) supports the 40 km reach. Confirm that the host device firmware supports 1000BASE-BX-U and DDM/DOM features; if necessary, test the module in your hardware prior to large deployments. Clean connector endfaces before mating and store modules in protective caps when not in use.
