## Long description

The BlueOptics 321-1659-BO QSFP LC Aluminium 20g is a fiber optic transceiver module engineered for high-speed network connectivity. Designed with a QSFP interface and LC duplex connector, this compact aluminium module weighs approximately 20 g and supports single-mode optical links. It is compatible with systems that accept QSFP form-factor transceivers and is intended for long-reach optical transmission in data center and carrier environments.
Advantages
This QSFP transceiver offers a compact, metal-housed design that supports high-bandwidth optical transmission while maintaining a low weight. The LC connector and QSFP interface conform to common MSA mechanical standards for interoperable deployment. The aluminium housing provides mechanical stability and thermal dissipation for continuous operation, and the module is suitable for environments requiring reliable fiber connectivity over single-mode fiber links.
Suitable for
 High-speed Ethernet and fiber channel uplinks in data centers
 Inter-switch links and aggregation ports
 Long-reach single-mode fiber connections between sites
 Network equipment in carrier and enterprise environments
Key specifications
 Interface type: QSFP
 Connector type: LC duplex
 Housing material: aluminium
 Weight: 0.02 kg
 Fiber type: single-mode (designed for long-reach optical links)
How to use
Install the module into a compatible QSFP port on your network device following the device manufacturer’s guidelines. Ensure the host device supports the QSFP module type and that any required firmware or software settings are enabled. Connect LC duplex single-mode patch cords to the module and to the corresponding remote transceiver or patch panel. Observe proper electrostatic discharge (ESD) precautions during handling and keep protective dust caps on connectors until final connection.
Usage recommendations
Verify compatibility with your switch or router vendor and enable any necessary port settings before full deployment. For optimal link quality, use verified single-mode fiber patch cords and maintain clean connector endfaces. Monitor link status through your host system's diagnostics and replace dust caps when the module is not in use.
