## Long description

The BlueOptics QSF-504-BO is a fiber optic transceiver module designed for 40 Gbit/s links. It uses a QSFP interface and operates at an 850 nm wavelength, supporting high-speed optical transmission over multimode fiber. The module is housed in a durable metal casing, has a compact form factor and a weight of 40 g, and requires an input voltage of 4 V. It is intended for use in networking equipment that accepts QSFP transceivers for short-range 40G data connectivity.
Advantages
The transceiver delivers 40,000 Mbit/s maximum data transfer rate over a QSFP interface and is engineered for consistent multimode fiber operation at 850 nm. Its metal housing provides mechanical protection and thermal stability while the compact, lightweight design facilitates installation in switches, routers and other network devices. The module’s adherence to QSFP physical interface conventions helps ensure interoperability with hardware that supports QSFP modules.
Suitable for
 Short-range 40G Ethernet links over multimode fiber
 High-density switch and router uplinks using QSFP ports
 Data center aggregation and server-to-switch connections
 Storage network links and high-throughput applications

How to use
Install the BlueOptics QSF-504-BO into a compatible QSFP port on supported network equipment following the vendor’s hot-swap and handling instructions. Connect appropriate multimode fiber patch cords (MPO/MTP or duplex LC depending on the system) to establish the optical link. Verify that the host device recognizes the module and that link status indicators show an active connection. Ensure the transceiver and receiving equipment are configured for the same 40G protocol and multimode fiber type.
Usage recommendations
Use multimode fiber and patch cords specified for 850 nm operation and keep fiber connectors clean to maintain signal quality. Confirm that the network hardware supports QSFP transceivers at 40 Gbit/s and that the device firmware or drivers allow the module to operate. Avoid exposure to excessive mechanical stress or extreme temperatures, and follow ESD precautions during handling.
