QSFP28 Transceiver BlueOptics QSFP28-100G-PSM4-IR-BO 100G 3.3V

The BlueOptics QSFP28-100G-PSM4-IR-BO is a 100G QSFP28 fiber optic transceiver module designed for high-speed single-mode optical links. It supports a maximum data transfer rate of 100000 Mbit/s over PSM4 architecture, uses an MPO/MTP connector and operates at 3.3V. The module is housed in a metal enclosure finished in silver, meeting MSA QSFP28 form-factor requirements for use in compatible network equipment.

Advantages

This QSFP28 transceiver provides interoperable 100GBASE-PSM4 connectivity in a compact QSFP28 form factor suitable for data center and carrier applications. Its metal housing offers mechanical durability and thermal conduction for reliable operation. The module supports simultaneous transmit and receive on multiple fibers via MPO/MTP interface and includes digital diagnostics monitoring for real-time information about supply voltage, laser bias current, optical output/input power and temperature when the host hardware exposes DDM/DOM data.

Suitable for

• High-density data center spine and leaf switches
• 100G aggregation and core links between switches and routers
• Storage and backup systems requiring 100G optical connectivity
• Carrier and metro optical links up to the supported PSM4 distance

Key specifications

• Interface type: QSFP28
• Maximum data transfer rate: 100000 Mbit/s (100 Gbps)
• Connector type: MPO/MTP (multi-fiber push-on)
• Optical medium: single-mode fiber (PSM4 architecture)
• Operating voltage: 3.3 V
• Form factor: QSFP28 metal housing, silver color
• Digital diagnostics: supports DDM/DOM monitoring (if supported by host)

How to use

Install the transceiver into a compatible QSFP28 slot on a switch, router or storage device following the host vendor's hot-plug procedures. Connect the MPO/MTP fiber patch cord to the module and route the fibers to the corresponding PSM4 breakout or remote MPO/MTP transceiver. Verify link status and DDM/DOM readouts via the host management interface if available. Ensure the host platform officially supports QSFP28 transceivers of this type to guarantee link negotiation and feature availability.

Recommendations

Use single-mode MPO/MTP patch cords and, where applicable, PSM4-compliant splitters or breakouts to achieve the specified 100G performance. Confirm that the receiving equipment and cabling plan match the PSM4 transmission scheme. Keep fiber connectors and MPO/MTP ferrules clean and avoid excessive bending of single-mode fiber to maintain signal quality and reduce attenuation.
