## Long description

The BlueOptics DEM-421XT-BO XFP LC Aluminium is a fiber optic XFP transceiver module designed for high-speed optical data links. Featuring an XFP interface and an LC duplex connector in a durable aluminium housing, this compact transceiver weighs 20 g and is intended for use in standard multimode fiber networks supporting up to 10 Gbit/s class transmission. It is built to industry MSA form-factor standards and provides reliable optical connectivity for compatible switching, routing and storage equipment.
Advantages
The module combines a standardized XFP interface with an LC connector and lightweight aluminium housing for broad interoperability and easy handling. Manufacturing to MSA guidelines ensures physical and electrical compatibility with major vendor platforms that accept XFP modules. The small form factor and low weight simplify installation in dense networking environments while the multimode-optimized optical design supports short-range 10 Gbit/s links.
Suitable for
10 Gbit/s multimode fiber links in data centers and enterprise networks
Use in switches, routers and storage systems with XFP ports
Patch panel or direct transceiver-to-transceiver connections using LC duplex fiber
Key specifications
Interface type: XFP
Connector: LC duplex
Housing material: aluminium (product colour: aluminium)
Weight: 0.02 kg
Optimized for multimode fiber short-range 10 Gbit/s links
How to use
Insert the XFP transceiver into a compatible XFP port on your switch, router or storage device, ensuring the device supports XFP modules and the intended optical link parameters. Connect an LC duplex multimode fiber patch cable to the transceiver’s LC port, observing correct transmit/receive orientation. After physical installation, verify link status in the host device and configure port settings (speed, duplex and any diagnostic features) according to the network equipment documentation.
Usage recommendations
Use high-quality multimode LC duplex patch cables and ensure connectors and fiber ends are clean before mating. Verify that the host hardware supports XFP transceivers and, if needed, enable digital diagnostic (DDM/DOM) features in the device firmware to monitor supply voltage, laser current, optical output and receive power and temperature. For best performance, follow vendor guidelines on maximum multimode reach and maintain proper fiber routing to avoid sharp bends.
