QSFP28 transceiver module BlueOptics 4M27A67042-BO 100m Aluminium

The BlueOptics 4M27A67042-BO is a QSFP28 fiber optic transceiver module designed for 100G connectivity over multimode fiber up to 100 meters. Housed in aluminium and weighing approximately 40 g, this 100GBASE-SR4 QSFP28 module uses an MPO/MTP connector and operates with 850 nm transmit and receive wavelengths. It follows MSA standards and supports common high-speed protocols such as Ethernet and Fibre Channel over Ethernet, offering a compact, durable component for data center and enterprise network links.

Advantages

The aluminium housing provides mechanical durability and helps dissipate heat while keeping the module lightweight. Compliance with QSFP28 and MSA specifications ensures broad compatibility with hardware that supports 100GBASE-SR4 optics. Integrated digital diagnostics (DDM/DOM) give real-time monitoring of supply voltage, laser bias current, transmitted and received optical power, and temperature, simplifying maintenance and troubleshooting.

Suitable for

• Short-reach 100 Gbps links in data centers (up to 100 m over multimode fiber)
• Interconnects between switches and routers supporting QSFP28
• High-performance compute and storage systems requiring 100GBASE-SR4 optics
• Multi-vendor environments where MSA-compliant transceivers are required

How to use

Install the BlueOptics QSFP28 transceiver into a compatible QSFP28 port on switches, routers, or network interface cards following the host hardware manufacturer’s insertion and removal procedure. Use an MPO/MTP multimode patch cable or a patch panel with appropriate multimode fibers to connect to the remote transceiver. Verify link status in the host device management interface and, if available, monitor DDM parameters to confirm optical power and temperature are within acceptable ranges. Ensure the host device firmware supports third-party MSA-compliant transceivers for best interoperability.

Usage recommendations

To maintain optimal performance, use OM3/OM4 multimode patch cords for runs up to the specified 100 m, keep fiber endfaces clean and use proper MPO/MTP cleaning tools, and confirm compatibility with the target hardware. Regularly check DDM readings to detect gradual degradations and replace modules showing out-of-spec parameters. Handle the module by its cage, avoid touching optical interfaces, and store unused transceivers with protective caps.
