## Summary description

The BlueOptics QSF-502T-BO is a fiber optic network transceiver module with a maximum data transfer rate of 40000 Mbit/s. It features a QSFP interface and operates at a wavelength of 850 nm. The module is housed in a durable metal casing and has an input voltage of 4 V. Weighing only 40 g, it is designed for efficient data transmission in high-speed networks.

## Long description

The BlueOptics QSF-502T-BO is a QSFP fiber optic transceiver module designed for 40 Gbit/s networks. It supports multimode transmission at an 850 nm wavelength and uses a QSFP interface in a compact metal housing. The module is lightweight and engineered for integration into switches, routers and other network hardware that accept QSFP transceivers, providing a standardized optical connection for high-speed data links over multimode fiber.
Advantages
This transceiver delivers a 40,000 Mbit/s maximum data rate over multimode fiber with MPO/MTP-style multi-fiber connectivity, enabling parallel optical lanes. The metal casing provides mechanical durability and thermal stability while the compact QSFP form factor supports high port density in network equipment. The module is compatible with common 40GBASE multimode applications and supports standardized operating characteristics for predictable performance in data center and enterprise environments.
Suitable for
40 Gbit/s Ethernet links in data centers and campus networks
High-bandwidth interconnects between switches, routers and servers
Short- to medium-range multimode fiber connections (using appropriate cabling)
Environments that require high port density and standardized QSFP modules
Key specifications
Interface type: QSFP (Quad Small Form-factor Pluggable)
Maximum data transfer rate: 40000 Mbit/s
Wavelength: 850 nm (multimode operation)
Connector type: MPO/MTP-compatible multi-fiber interface (parallel MPO)
Housing: metal casing for thermal and mechanical stability
Weight: approximately 0.04 kg
Recommended fiber: multimode fiber suitable for 40GBASE multimode protocols
How to use
Insert the module into a compatible QSFP port on your network device while the device is powered down or following the vendor's hot-plug guidance. Connect the MPO/MTP multimode patch cable to the module and to the corresponding transceiver or patch panel, ensuring correct fiber polarity and alignment. Verify link status on your switch or router and check that optics are recognized and operating at the expected 40 Gbit/s rate. Monitor device diagnostics where supported to confirm optical power and temperature are within acceptable ranges.
Usage recommendations
Use high-quality multimode MPO/MTP patch cords and follow equipment vendor guidelines for compatibility and firmware requirements. If digital diagnostic monitoring (DDM/DOM) is available in your host device, enable and review the optical parameters to support ongoing troubleshooting and preventive maintenance. For optimal performance, keep connector end-faces clean and use appropriate dust caps when modules are not in use.
