Optický transceiver modul BlueOptics AT-QSFP28-LR4-BO 1000000 Mbit/s

The BlueOptics AT-QSFP28-LR4-BO fiber optic transceiver module is designed for high-speed single-mode fiber connections with a QSFP28 interface. It supports data transfer rates up to 1,000,000 Mbit/s and provides duplex LC connectivity for simultaneous transmit and receive channels. The module is housed in an aluminium casing and weighs approximately 40 g, making it suitable for installation in compatible network equipment that accepts QSFP28 transceivers.

Advantages

This QSFP28 transceiver follows MSA-aligned QSFP28 mechanical and electrical specifications to ensure interoperability with systems supporting comparable QSFP28 modules. Its single-mode optical design and CWDM-enabled transmitter and receiver support long-reach fiber links. The aluminium housing provides a durable, lightweight form factor and the module includes digital diagnostic monitoring capability when the host hardware supports DDM/DOM, enabling remote readout of operational parameters for maintenance and troubleshooting.

Suitable for

• 100G Ethernet and other high-speed optical networking links over single-mode fiber
• Connections between switches, routers, storage systems and transceivers in data centers
• Long-reach links up to typical LR4 ranges for backbone and campus interconnects

Key specifications

• Interface type: QSFP28
• Maximum data transfer rate: 1000000 Mbit/s
• Optical medium: single-mode fiber (LC Duplex)
• Transceiver class: LR4 (long reach, CWDM-based channels)
• Material / colour: aluminium housing
• Weight: 0.04 kg
• Support for digital diagnostic monitoring (DDM/DOM) when enabled by host

How to use

Install the BlueOptics AT-QSFP28-LR4-BO into a QSFP28-compatible port on a switch, router or other networking device that supports LR4 QSFP28 transceivers. Connect LC Duplex single-mode fiber patch cords to the transceiver's LC interfaces, ensuring correct Tx/Rx orientation. Verify that the host device supports the module's DDM/DOM functions if monitoring is required. Follow the host vendor's instructions for enabling and verifying optical link parameters and for any required firmware or configuration adjustments.

Recommendations

Use high-quality single-mode LC Duplex patch cords and, where possible, install the transceiver in equipment that officially supports LR4 QSFP28 modules to ensure compatibility. Observe ESD precautions during handling, verify cleanliness of fiber connectors before mating, and confirm that the host system's DDM/DOM support is enabled if remote diagnostics are needed.
