## Long description

The BlueOptics MP-S31121-3CDL10-BO is a compact fiber optic SFP transceiver module designed for single-mode links with an LC interface and a maximum data rate of 1250 Mbit/s. It is intended for reliable optical data transmission over suitable single-mode fiber cabling and complies with CE, RoHS and FCC standards. The module is lightweight (approximately 20 g) and finished in a silver housing, matching common MSA-compliant SFP form-factor slots in network equipment that support 1000BASE-LX style connections.
Advantages
The module delivers a standardized LC duplex connection and supports up to 1250 Mbit/s data throughput, enabling Ethernet and other high-speed optical transport protocols on single-mode fiber. Compliance with CE, RoHS and FCC indicates adherence to common safety and environmental requirements. Its small size and low weight simplify installation and replacement in switches, routers and other transceiver slots designed for SFP modules.
Suitable for
 Point-to-point single-mode fiber links using LC connectors
 Gigabit Ethernet and related optical networking applications up to 1.25 Gbit/s
 Installation in SFP-compatible switches, routers or storage/network appliances
 Network equipment requiring CE, RoHS and FCC compliant transceivers
Key specifications
 Form factor: SFP (MSA-compatible)
 Interface: LC duplex
 Maximum data rate: 1250 Mbit/s
 Fiber type: single-mode (designed for long-reach single-mode transmission)
 Typical application: 1000BASE-LX class optical links
 Housing colour: silver
 Weight: approximately 0.02 kg
 Regulatory compliance: CE, RoHS, FCC
How to use
Install the BlueOptics SFP module into an empty SFP slot of a compatible network device, ensuring the device supports 1000BASE-LX style optics or the equivalent SFP transceiver class. Connect LC duplex fiber patch cables to the module, observing transmit/receive orientation. Power on the equipment and verify link status in the host device management interface. If the host supports digital diagnostic monitoring (DDM/DOM), enable or query that function to view real-time parameters if available.
Usage recommendations
Use single-mode LC duplex patch cords and appropriate patch panels for best optical performance. Confirm that the target device firmware or hardware supports third-party SFP modules if interoperability is a concern. Keep fiber connectors clean and follow standard ESD precautions when inserting or removing the transceiver.
