QSFP28 Transceiver BlueOptics QSFP28-100G-PSM4-BO 100G 100000 Mbit/s

The BlueOptics QSFP28-100G-PSM4-BO is a 100G fiber optic transceiver module with a QSFP28 interface designed for high-speed data transfer in data centers and high-performance computing environments. Housed in a metal casing and weighing just 2 g, this transceiver supports 100000 Mbit/s throughput and connects via an MPO/MTP connector for single-mode fiber links. It implements 100GBASE-PSM4 optical transmission suitable for short single-mode spans and includes transmitter and receiver channels with CWDM to enable aggregated 100 Gbit/s links over multiple fibers.

Advantages

The module is built to MSA-compliant QSFP28 form factor standards, offering interoperability with hardware platforms that accept QSFP28 100GBASE-PSM4 optics. Its metal housing provides mechanical durability and thermal conductance, while the low weight and compact size simplify installation in dense networking racks. The transceiver supports digital diagnostics (DDM/DOM) for real-time monitoring of voltage, laser bias current, transmit power, receive power and temperature, aiding remote maintenance and error analysis. Components are selected for long operational lifetime and high MTBF to maximise availability in critical network infrastructures.

How to use

Install the QSFP28 transceiver into a compatible QSFP28 port on a switch, router or other networking device, ensuring the host hardware supports 100GBASE-PSM4 optics and the DDM/DOM feature if monitoring is required. Connect an MPO/MTP single-mode patch cable between transceiver endpoints or via a panel. Observe ESD precautions and handle the module by its edges; remove dust caps only when making the optical connection. Verify link status and diagnostic readings through the host management interface after insertion to confirm proper operation.

Usage recommendations

Use high-quality MPO/MTP single-mode patch cords and follow vendor guidelines for fiber routing and bend radius. Ensure the host device firmware supports third-party QSFP28 modules and enable DDM/DOM monitoring where available to track optical parameters and detect degradation early.
