40G QSFP Transceiver BlueOptics 40G-QSFP-SR4-KY-BO Fiber Optic 150m

The BlueOptics 40G-QSFP-SR4-KY-BO is a 40GBASE-SR4 multimode fiber optic transceiver module designed for 40 Gigabit Ethernet and other high-speed optical applications. The QSFP form factor provides compact, hot-pluggable connectivity with an MPO/MTP interface and supports multimode fiber transmission up to 150 meters. Housed in aluminum and weighing approximately 20 g, the module complies with MSA-compatible mechanical and electrical specifications and is suitable for data center, campus and enterprise network deployments where short-reach 40 Gbps links are required.

Advantages

The transceiver offers high data throughput at 40 Gbps with a multimode optical design using 850 nm lasers for simultaneous transmit and receive channels. An aluminum housing provides mechanical robustness and heat dissipation while maintaining a light overall weight. Compliance with industry MSA standards ensures broad interoperability with QSFP-capable switches, routers and storage systems. Digital Diagnostics Monitoring (DDM/DOM) support enables real-time monitoring of supply voltage, laser bias current, output and received power, and temperature for simplified maintenance and troubleshooting.

Suitable for

• 40 Gigabit Ethernet links in data centers and aggregation layers
• High-speed interconnects between switches, routers and storage systems
• Fibre Channel over Ethernet and SDH/SONET short-reach optical links
• Environments requiring MSA-compliant QSFP modules with MPO/MTP connectors

Key specifications

• Form factor: QSFP (Quad Small Form-factor Pluggable)
• Wavelength: 850 nm (transmit and receive)
• Maximum link distance: up to 150 m over multimode fiber
• Connector type: MPO/MTP
• Data rate: 40 Gbps (40GBASE-SR4)
• Housing material: aluminium
• Weight: approximately 0.02 kg
• Digital Diagnostics Monitoring (DDM/DOM): supported (MSA SFF-8472 compliant)

How to use

Install the QSFP transceiver into a compatible QSFP port on a switch, router or host adapter while the system is powered according to the equipment vendor’s instructions. Connect an appropriate MPO/MTP multimode fiber patch cord or patch panel assembly matching the fiber type (e.g., OM3/OM4) to achieve the specified reach. Ensure host hardware and firmware support 40GBASE-SR4 and DDM/DOM if monitoring is required. After insertion, verify the link status and DDM readings via the network equipment management interface and perform necessary link testing with suitable optical test equipment.

Recommendations

For optimal performance, use OM3 or OM4 multimode fiber and high-quality MPO/MTP patch cords. Confirm compatibility with the host device vendor and keep device firmware up to date to ensure DDM/DOM functionality. Avoid bending or stressing fiber cables and operate the module within the manufacturer’s specified temperature and power ranges to maintain long-term reliability.
