The module is lightweight at 20 g and comes in an aluminum casing, ensuring durability and efficiency in data communication applications.

## Long description

The BlueOptics X65401-BO is a QSFP fiber optic transceiver module designed for high-speed links with a maximum data rate of 40000 Mbit/s. Operating at a wavelength of 850 nm, this compact transceiver in an aluminium housing weighs 20 g and is intended for multimode fiber connections with MPO/MTP connectivity. The module implements 40GBASE-SR4 optical signaling and supports common high-speed transport protocols used in switches, routers and storage systems.
Advantages
The module is built to MSA-compliant QSFP specifications and is compatible with equipment that supports the NetApp X65401 40GBASE-SR4 QSFP form factor. Robust aluminium casing and a lightweight design provide physical durability while keeping installation simple. The transceiver supports simultaneous transmit and receive channels via MPO/MTP connection for efficient four-lane 40 Gbit/s operation. Digital diagnostics (DDM/DOM) are supported when the host hardware exposes the interface, allowing remote monitoring of supply voltage, temperature, laser bias current and optical power.
Suitable for
Short-reach 40 Gbit/s links over multimode fiber (up to typical distances for 850 nm SR4)
High-performance switches, routers and storage systems that accept QSFP 40G modules
Data center aggregation and spine-leaf network segments
Fibre Channel over Ethernet and other 40G network applications
Key specifications
Interface type: QSFP (Quad Small Form-factor Pluggable)
Maximum data transfer rate: 40000 Mbit/s (40 Gbit/s)
Operating wavelength: 850 nm
Connector: MPO/MTP for multimode parallel optics
Form factor: QSFP 40GBASE-SR4 compatible
Housing material and colour: aluminium (silver)
Typical application medium: multimode fiber
Weight: 0.02 kg
How to use
Insert the BlueOptics X65401-BO QSFP module into a compatible QSFP port on switches, routers or storage equipment while the host device is powered down or following the vendor’s hot-plug procedures. Connect an MPO/MTP multimode patch cable to the module and route the other end to the intended optical interface or patch panel. Ensure the host firmware and port configuration support 40GBASE-SR4 and, if required, enable or verify Digital Diagnostics Monitoring (DDM/DOM) support in the host to access real-time diagnostic parameters.
Usage recommendations
Use high-quality multimode MPO/MTP patch cords and follow manufacturer guidelines for fiber type and maximum link length for 850 nm SR4 operation. Verify compatibility with the specific host platform and keep firmware updated to ensure link stability and access to DDM information.
