## Summary description

The BlueOptics 21265784-BO is a fiber optic SFP+ transceiver module designed for high-speed data transmission. It features an LC connector and is made of durable aluminium, weighing only 20g. This module is ideal for networking applications requiring reliable and efficient performance.

## Long description

The BlueOptics 21265784-BO SFP+ LC Aluminium 20g is a fiber optic transceiver module designed for high-speed short-range optical data transmission. It implements the SFP+ form factor with an LC duplex connector and an aluminium housing, providing a compact, lightweight module for 10G optical links over multimode fiber. The module supports 850 nm transmission and reception and is built to MSA physical and electrical standards for broad compatibility with network switches, routers and storage systems that accept SFP+ modules.
Advantages
The transceiver offers a standardized SFP+ interface in a durable aluminium enclosure and a low weight of 20 g, simplifying installation and hot-plug replacement. Built to MSA-compliant specifications, the module is suitable for widely used short-range 10GBASE-SR applications and supports simultaneous transmit and receive functions via the LC duplex connector. The design minimizes susceptibility to electromagnetic interference inherent to copper links by using optical transmission.
Suitable for
 10 Gigabit Ethernet short-range links (10GBASE-SR) over multimode fiber
 Inter-switch connections in data center racks and wiring closets
 Server-to-switch and storage network uplinks
 High-speed links in enterprise LAN and campus networks
Key specifications
 Form factor: SFP+
 Connector type: LC duplex
 Optical wavelength: 850 nm (multimode)
 Maximum data rate: up to 10 Gbit/s
 Typical reach: short-range multimode fiber (up to around 300 m depending on fiber type)
 Housing material: aluminium
 Weight: 20 g
 MSA-compliant electrical and mechanical interface
How to use
Install the module into an SFP+ slot on a compatible switch, router or host adapter while the device is powered on if hot-plugging is supported. Connect LC duplex multimode fiber patch cords ensuring correct orientation for transmit and receive fibers. Verify the link status on the network device and confirm supported speeds and protocols in the host hardware. If the host supports digital diagnostics (DDM/DOM), monitor module parameters such as optical power and temperature through the management interface where available.
Usage recommendations
For optimal performance, use high-quality multimode fiber (OM3/OM4) and LC duplex patch cords, keep fibre endfaces clean, and ensure SFP+ slot firmware or vendor settings allow third-party transceivers. Confirm the supported link distance for your specific multimode grade and check whether the hosting hardware provides DDM/DOM support if remote diagnostics are required.
