SFP-lähetin-vastaanotinmoduuli BlueOptics SFP-BXU34-40KM-MR-BO 1250 Mbit/s

The BlueOptics SFP-BXU34-40KM-MR-BO is a single‑mode fiber optic SFP transceiver module designed for 1000BASE‑BX‑U applications with a maximum data transfer rate of 1250 Mbit/s. The module comes in a metal housing with a silver finish and a compact form factor suitable for SFP slots. It supports LC simplex connections and is specified for long‑reach links up to 40 km over single‑mode fiber. The product provides high availability with an MTBF of 1,000,000 hours and a lightweight design of approximately 20 g.

Advantages

The module implements an SFP electrical and mechanical interface according to MSA standards, enabling interoperability with a wide range of network equipment that supports 1000BASE‑BX‑U SFP transceivers. It uses separate transmit and receive wavelengths for bi‑directional operation over a single fiber, supports Digital Diagnostic Monitoring (DDM/DOM) when the host hardware provides support, and is built with a metal housing for mechanical stability and thermal performance. With an MTBF of 1,000,000 hours and a small 20 g weight, the transceiver is suited for deployments where reliability and compactness are required.

Key specifications

How to use

Install the transceiver into an empty SFP port on compatible network equipment following the device manufacturer’s hot‑plug and electrostatic discharge (ESD) procedures. Connect an LC simplex single‑mode fiber patch cable to the LC port, observing correct polarity for BX operation (separate fibers for Tx and Rx endpoints). Verify link status in the host device management interface and enable DDM/DOM monitoring if available to observe optical parameters such as input/output power and temperature. Remove protective dust caps from the connector before insertion and keep spare caps for storage to avoid contamination.

Recommendations

Use high-quality single‑mode fiber and certified LC simplex patch cords to achieve the specified reach and signal margins. Ensure the host equipment supports 1000BASE‑BX‑U and DDM/DOM if remote diagnostics are required. Follow standard ESD precautions during handling and avoid bending the fiber beyond recommended bend radius to maintain performance and service life.
