Transceiver BlueOptics BU8E-BO QSFP MPO/MTP 40GBASE-SR4 multimode 4×850nm 150m 0–70°C

Compatible BlueOptics BU8E-BO QSFP optical transceiver for 40GBASE-SR4 links. This hot-pluggable module supports MPO/MTP connectors and uses four 850 nm transmit/receive lanes over multimode fiber, providing reliable short-range 40 Gbit/s links with a typical reach of up to 150 meters. The transceiver is intended for data center and enterprise environments, enabling switch-to-switch and switch-to-server connections with an operating temperature range of 0°C to 70°C and a QSFP form factor for high-density installations.

Advantages

The module delivers 40GBASE-SR4 performance using four parallel 850 nm lanes, supporting multimode fiber to simplify short-reach network design. Its MPO/MTP connector offers quick, standardized fiber connections and the hot-pluggable QSFP form factor allows fast replacement or upgrades without powering down equipment. Wide operating temperature tolerance ensures stable operation in standard data center and enterprise racks. Compatibility with common QSFP ports helps integrate the transceiver into existing infrastructures.

Key specifications

How to use

Install the QSFP transceiver into a compatible QSFP port on your switch or server according to the host device instructions. Connect a matching MPO/MTP multimode fiber assembly with appropriate fiber grade (OM3/OM4 as required) to achieve the specified reach. Ensure proper fiber polarity and secure connections. After insertion, verify link status on the host device and confirm 40 Gbit/s operation through management interfaces or diagnostic LEDs.

Recommendations

For optimal performance, use certified multimode fiber (OM3 or OM4) and MPO/MTP cabling assemblies rated for 40GBASE-SR4. Keep fiber connectors clean and handle the transceiver in electrostatic-safe conditions. Match the transceiver to compatible QSFP ports and firmware where interoperability information is available. For runs near the maximum reach, prefer higher-grade multimode fiber and verify link margin with diagnostic tools.
