## Summary description

The BlueOptics SFP-BXU35-20KM-CN-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. Ideal for reliable network connections over long distances.

## Long description

The BlueOptics SFP-BXU35-20KM-CN-BO is a single-mode fiber SFP transceiver module supporting a maximum data rate of 1250 Mbit/s. Housed in a metal casing and weighing approximately 20 g, this SFP module is designed for point-to-point fiber links up to 20 kilometres and follows MSA mechanical specifications. It implements a bidirectional 1000BASE-BX-U optical interface using LC simplex connectors with separate transmit and receive wavelengths for single-fibre operation.
Advantages
The module provides a compact, hot-pluggable SFP form factor compatible with network devices that support 1000BASE-BX-U optics. A metal housing offers mechanical robustness and thermal dissipation, while a mean time between failures (MTBF) of 1,000,000 hours indicates long operational life for reduced maintenance. Compliance with industry MSA standards ensures interoperability with switches, routers and other SFP-capable equipment, and the design supports Digital Diagnostics Monitoring when the host platform provides DDM/DOM support.
Suitable for
Long-distance single-mode Ethernet links up to 20 km
Interconnecting switches and routers in WAN or campus networks
Fiber uplinks for storage systems and network appliances
Replacement or expansion of SFP ports on compatible hardware
Key specifications
Interface type: SFP (Small Form-factor Pluggable)
Data rate: up to 1250 Mbit/s (1.25 Gbit/s)
Optical type: single-mode, bidirectional 1000BASE-BX-U
Wavelengths: separate transmit and receive wavelengths (TX/RX) for single-fibre operation
Connector: LC simplex
Maximum reach: up to 20 kilometres over single-mode fiber
Housing: metal
Weight: approx. 0.02 kg
MTBF: 1,000,000 hours
How to use
Insert the SFP transceiver into any compatible SFP slot on a switch, router or other network device while the host is powered on or according to the device manufacturer’s hot-swap guidance. Connect an appropriate single-mode LC simplex patch cable between this transceiver and the remote transceiver, ensuring correct orientation of transmit and receive ends for BX-U operation. Verify link negotiation and speed settings on both ends and enable DDM/DOM in the host system if monitoring of optical parameters is required.
Usage recommendations
For best performance, use single-mode fiber and LC simplex patch cords rated for 1310/1550 nm, keep connectors clean and install transceivers in equipment that officially supports 1000BASE-BX-U SFP modules. Confirm that the host device supports DDM/DOM if you require real-time diagnostics, and follow the equipment manufacturer’s thermal and handling guidelines to maintain the stated MTBF and operational stability.
