Módulo transceptor SFP BlueOptics SFP-BXU35-20KM-PA-BO 1250 Mbit/s

The BlueOptics SFP-BXU35-20KM-PA-BO is a single-mode fiber SFP transceiver module designed for duplex optical communication over long distances. It supports a maximum data transfer rate of 1250 Mbit/s (1.25 Gbit/s) and uses an LC simplex connector with a bidirectional (BX) configuration: a transmitter operating at 1550 nm and a receiver at 1310 nm. The module is housed in metal for mechanical stability and has an MTBF of 1,000,000 hours, making it suitable for continuous high-speed links up to 20 km when used with appropriate single-mode fiber.

Advantages

The transceiver offers compatibility with equipment that supports 1000BASE-BX-U SFP modules and adheres to MSA electrical and mechanical specifications, ensuring interoperability across different vendors. Its metal housing and compact SFP form factor minimize wear while providing electromagnetic immunity inherent to fiber optic transmission. Built-in digital diagnostics (DDM/DOM) provide real-time monitoring of supply voltage, laser bias current, transmit power, receive power and temperature when supported by the host hardware. The combination of industry-standard components and an MTBF of 1,000,000 hours contributes to long-term availability and reliable operation.

How to use

Insert the SFP transceiver into an SFP slot on a compatible device while the device is powered according to the vendor’s instructions or hot-swap guidelines. Terminate the single-mode fiber with LC connectors and connect the LC simplex patch cable between transceivers; ensure the correct pairing for BX operation (TX at 1550 nm to RX at 1550 nm on the opposite end and vice versa for 1310 nm). Verify link status and, if available, read DDM/DOM values from the host to confirm proper power and temperature parameters. Follow the network equipment manufacturer’s firmware and compatibility notes to enable proper operation.

Recommendations

Use high-quality single-mode fiber and LC patch cords to achieve the specified 20 km reach. Confirm that the host device supports 1000BASE-BX-U and DDM/DOM if remote diagnostics are required. Observe ESD precautions during handling, and keep connectors clean to avoid signal loss. For interoperability, test the module in your hardware environment before large deployments.
