SFP transceiver module BlueOptics 02310KVU-BO 1250 Mbit/s 1490 nm

The BlueOptics 02310KVU-BO SFP transceiver module is a compact optical interface for single-mode fiber networks. Designed for 1000BASE-BX-D operation, it supports a data rate of up to 1250 Mbit/s and uses a 1490 nm receiver wavelength with a transmitting wavelength pair for bidirectional single-fiber links. The module features an LC simplex connector, a silver housing and a lightweight design of approximately 20 g, suitable for integration into switches, routers and media converters that accept MSA-compliant SFP form factors.

Advantages

The module implements MSA-compliant mechanical and electrical characteristics to ensure interoperability with a broad range of networking hardware. It supports long-reach links up to 40 km over single-mode fiber and includes digital diagnostic monitoring (DDM/DOM) capability when supported by the host device, enabling real-time reporting of parameters such as supply voltage, laser bias current, received optical power and temperature. The compact SFP format and LC connector simplify installation and replacement in dense rack environments.

Suitable for

• 1 Gbit Ethernet links over single-mode fiber
• Long-distance backbone connections up to 40 km
• Interconnecting switches, routers, storage systems and media converters
• Environments requiring DDM/DOM monitoring for troubleshooting and maintenance

Key specifications

• Maximum data transfer rate: 1250 Mbit/s
• Transmitter/receiver wavelengths: 1310 nm (TX) / 1490 nm (RX) for bidirectional single-fiber operation
• Maximum transfer distance: up to 40,000 m (40 km) on single-mode fiber
• Connector type: LC simplex
• Module weight: approximately 0.02 kg
• Housing colour: silver
• Form factor: SFP (MSA-compliant)
• Digital diagnostics: DDM/DOM support (if supported by host hardware)

How to use

Insert the SFP transceiver into a compatible SFP port on the host device until it clicks into place, then secure any retaining mechanisms according to the device manufacturer’s instructions. Connect an appropriate single-mode LC patch cable to the module; for bidirectional BX links ensure correct pairing of TX and RX wavelengths at each link end (1310 nm/1490 nm configuration). Verify link status and, if available, read DDM/DOM parameters from the host to confirm optical power levels and operating conditions. Follow the host equipment’s procedures for enabling or configuring the interface as needed.

Recommendations

Use certified single-mode LC patch cords and ensure correct fiber polarity for BX single-fiber operation. Confirm that the target hardware supports DDM/DOM if remote diagnostics are required. Observe ESD precautions when handling the module and cap the optical connector when not connected to prevent contamination. For reliable long-distance links, inspect fiber endfaces and maintain specified optical power margins to avoid performance degradation.
