QSFP Transceiver Module BlueOptics QSFP-40G-SR4-MV-BO 40 Mbit/s 850 nm

The BlueOptics QSFP-40G-SR4-MV-BO is a QSFP transceiver module for high-speed optical data links. It supports a maximum aggregated data rate of 40 Mbit/s over multimode fiber using 850 nm optics. The module is housed in a metal casing, requires a 3.3 V input supply and is specified with a mean time between failures (MTBF) of 1,000,000 hours, making it suitable for continuous networking operation.

Advantages

The module follows QSFP form-factor and MSA-defined mechanical and electrical standards to ensure interoperability with compatible hardware. Its MPO/MTP connector design allows simultaneous transmit and receive channels through multimode fiber. The metal housing provides mechanical durability and thermal stability, while the low input voltage requirement simplifies integration into standard networking equipment. Built-in monitoring capabilities provide diagnostic information useful for remote maintenance when supported by host hardware.

Suitable for

• 40G Ethernet links over multimode fiber within data centers and aggregation points
• High-speed interconnects between switches, routers and storage systems
• Applications requiring MPO/MTP connections and short-reach optical transmission

How to use

Install the module into a compatible QSFP slot on supported networking equipment following the host vendor's hot-swap and handling procedures. Connect an MPO/MTP multimode fiber patch cord to the transceiver and to the corresponding port or patch panel on the remote device. Verify link status and, if available, read digital diagnostic monitoring (DDM/DOM) parameters from the host system to confirm proper supply voltage, transmit/receive power levels and temperature. Ensure the host platform supports the required data protocols and QSFP module type.

Recommendations

Use multimode fiber rated for short-reach 850 nm transmission and maintain clean MPO/MTP connectors to preserve optical performance. Confirm DDM/DOM support on the host device to enable diagnostic readings. Follow anti-static handling precautions, avoid exceeding the specified input voltage, and consult the equipment compatibility list before deployment.
