## Summary description

The BlueOptics SFP-6521-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 10000 Mbit/s. It features a metal housing, operates at an input voltage of 3.3 V, and weighs only 3 g. Ideal for high-speed data communication applications.

## Long description

The BlueOptics SFP-6521-BO is a compact fiber optic SFP transceiver module designed for high-speed data communication with a maximum transfer rate of 10000 Mbit/s. Housed in a metal casing and weighing approximately 3 g, it operates at 3.3 V and provides a silver-coloured SFP interface suitable for single-mode fiber links using an LC simplex connector. The module supports 10G optical networking applications and follows MSA-compatible form factor and interface conventions for use in compatible switches, routers, storage systems and other network hardware.
Advantages
The transceiver combines a small, lightweight metal housing with industry-standard SFP connectivity to deliver reliable 10G data transmission while keeping thermal and mechanical stability. Its low input voltage requirement (3.3 V) and standard SFP interface make integration straightforward in equipment that supports SFP modules. The module’s single-mode LC simplex connection and optical design are aimed at minimizing electromagnetic interference and providing stable long-distance optical links.
Suitable for
10G Ethernet links over single-mode fiber
High-speed connections between switches, routers and storage systems
Optical backbone links and point-to-point fiber connections
Environments requiring low EMI and long-distance optical transmission
Key specifications
Interface type: SFP (LC simplex)
Maximum data transfer rate: 10000 Mbit/s
Optical fiber type: Single-mode fiber (typical for 10GBX applications)
Housing: Metal
Operating input voltage: 3.3 V
Weight: 0.003 kg
Product colour: Silver
How to use
Insert the SFP transceiver into a compatible SFP slot on your network device until it latches, then connect a matching LC simplex single-mode fiber patch cable. Ensure the host device supports SFP modules and the intended 10G protocol (for example 10GBASE-BX-D or equivalent 10G standards). Power on the equipment and verify link status via the host device management interface. If the device supports digital diagnostics (DDM/DOM), enable or read diagnostic values through the device’s monitoring tools to check supply voltage, optical transmit/receive power and temperature.
Usage recommendations
For optimal performance, use high-quality single-mode fiber patch cords and compatible LC connectors, and verify that your network hardware explicitly supports SFP 10G modules. When available, use the host device’s DDM/DOM diagnostics to monitor optical parameters and ensure correct installation and stable operation.
