Netwerktransceivermodule BlueOptics BO25K859S3D-BO 40 Mbit/s QSFP

The BlueOptics BO25K859S3D-BO is a QSFP network transceiver module engineered for point-to-point fiber connections and high-density networking equipment. With a maximum data transfer rate of 40 Mbit/s and an LC fiber optic connector, this compact module supports straightforward integration into compatible switches and routers. Its small form factor and lightweight construction (40 g) make it suitable for installations where space and weight are considerations. The module is available in cream and grey finishes to match various equipment aesthetics.

Advantages

The module provides a standardized QSFP interface for interoperability with network hardware that accepts QSFP form-factor transceivers. Its LC connector ensures compatibility with commonly used single- and multi-mode fiber patching infrastructure. At 40 Mbit/s, the transceiver is designed for moderate bandwidth links where reliable fiber connectivity is required. The unit’s low weight and compact size simplify handling and mounting in rack or chassis environments.

Suitable for

• Fiber optic links between switches and routers in small to medium networks
• Backup or auxiliary uplink connections where moderate bandwidth is sufficient
• Environments requiring QSFP form-factor modules for modular chassis or transceiver cages
• Installations where lightweight, compact transceivers improve density and airflow

Key specifications

• Interface type: QSFP
• Maximum data transfer rate: 40 Mbit/s
• Connector type: LC fiber optic
• Product colour: cream and grey options
• Weight: 0.04 kg

How to use

Install the transceiver into a compatible QSFP slot on your network device following the device manufacturer’s guidance for hot-plugging or shut-down procedures. Connect the LC-terminated fiber cable to the transceiver’s LC connector, ensuring proper polarity and secure mating. After physical installation, verify link status through the network device’s management interface and configure the port for the intended data rate and duplex settings if required. Handle the module using antistatic precautions and keep protective dust caps on the connector when not in use.

Recommendations

Use the BlueOptics BO25K859S3D-BO in systems that support QSFP transceivers and LC fiber connections. Ensure fiber type (single-mode or multi-mode) and connector polarity match the network design. For consistent performance, maintain clean connector endfaces and follow manufacturer guidelines for insertion/removal and environmental operating conditions.
