## Summary description

Extralink SFP 1.25G multimode transceiver module kit (2-pack) supports 1.25 Gbps data rate, 850 nm wavelength, LC/UPC connector and up to 550 m reach over multimode fiber. The modules include DOM for optical diagnostics and are designed for switching, routing and fiber uplink applications in campus and enterprise networks.

## Long description

Extralink SFP 1.25Gbps LC/UPC 850nm multimode transceiver kit (2-pack) provides two hot-pluggable modules designed for fiber uplink and network aggregation. Each module supports a 1.25 Gbps data rate and uses an 850 nm VCSEL light source with LC/UPC duplex optical connectors. The transceivers are intended for short-reach multimode fiber links up to 550 meters and include digital optical monitoring (DOM) capability for real-time diagnostics of transmit power, receive power, temperature and supply voltage.
Advantages
The modules deliver reliable 1.25 Gbps connectivity for switches, routers and media converters in campus and enterprise environments. Compact SFP form factor allows flexible port upgrades without replacing networking equipment. Integrated DOM simplifies maintenance and fault detection by providing optical parameter reporting. Using LC/UPC connectors and multimode fiber compatibility ensures straightforward installation in existing fiber cabling infrastructures.
Suitable for
 1 Gbps fiber uplinks between switches and routers within campus or office networks
 Fiber connections to servers, storage arrays or media converters over multimode cabling
 Short-reach aggregation links in enterprise wiring closets and equipment rooms
 Replacement or expansion of SFP ports on managed network devices
Key specifications
 Data rate: 1.25 Gbps
 Wavelength: 850 nm
 Connector type: LC/UPC duplex
 Fiber type: Multimode fiber (MMF)
 Maximum reach: Up to 550 m (over suitable multimode fiber)
 Form factor: SFP (hot-pluggable)
 Monitoring: Digital Optical Monitoring (DOM)
 Typical application: Short-reach multimode links for switching and routing
How to use
Power off or isolate the target device if recommended by the equipment vendor, then insert the SFP module into an available SFP slot until it clicks into place. Connect the LC/UPC duplex patch cable between the module and the multimode fiber link, observing correct transmit-to-receive fiber alignment. After installation, verify link status and speed on the host device and use DOM readouts to confirm optical power and module health. Modules are hot-pluggable on most devices that support industry-standard SFP transceivers.
Usage recommendations
Use appropriate multimode fiber (OM1/OM2/OM3/OM4 as supported by your cabling) and LC duplex patch cords. Ensure cleanliness of LC connectors before mating and avoid bending the fiber beyond manufacturer bend-radius limits. Check compatibility lists of switches or routers for SFP transceiver support and enable DOM monitoring in management interfaces for proactive diagnostics.
