## Summary description

The BlueOptics TXN31111-BO is a fiber optic SFP transceiver with a maximum data transfer rate of 1250 Mbit/s. It features a metal housing for durability and has a mean time between failures (MTBF) of 1,000,000 hours. Weighing only 20 g, it is designed for efficient performance in network applications.

## Long description

The BlueOptics TXN31111-BO is a Small Form-factor Pluggable (SFP) fiber optic transceiver designed for 1000Base-SX networks with a maximum data transfer rate of 1250 Mbit/s. Housed in a durable metal casing and weighing 20 g, this module supports LC duplex connections over multimode fiber and is built to industry MSA mechanical and electrical standards. The transceiver provides a practical solution for connecting switches, routers and storage equipment where 1.25 Gbit/s optical links are required.
Advantages
The BlueOptics TXN31111-BO offers compatibility with standard SFP interfaces and conforms to MSA guidelines, enabling interoperability with a broad range of network hardware. Its metal housing improves durability and thermal conduction while the compact SFP form factor allows hot-pluggable installation. The module’s mean time between failures (MTBF) of 1,000,000 hours indicates a long operational lifetime for stable network deployments.
Suitable for
 Establishing 1000Base-SX links over multimode fiber
 Upgrading or replacing SFP ports in switches, routers and storage systems
 Short- to medium-range optical connections within data centres and campus networks
Key specifications
 Interface type: SFP (hot-pluggable)
 Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
 Optical connector: LC duplex (multimode fiber)
 Transmitter/Receiver wavelength: 850 nm (multimode operation)
 Housing: metal
 Weight: 0.02 kg
 Mean Time Between Failures (MTBF): 1,000,000 hours
How to use
Install the BlueOptics TXN31111-BO by inserting the SFP module into a compatible SFP port on your switch, router or storage device while the equipment is powered according to the vendor’s hot-plug instructions. Connect an LC duplex multimode fiber patch cable between transceivers, observing correct transmit/receive orientation. Verify link status and negotiated speed on the host device. If Digital Diagnostics Monitoring (DDM/DOM) is supported by the host hardware, you can monitor supply voltage, optical power and temperature through the management interface of the network device.
Usage recommendations
Use multimode fiber and LC duplex patch cords rated for 850 nm and ensure connectors and patch panels are clean to maintain optical performance. Confirm that the target hardware supports MSA-compliant SFP modules to avoid compatibility or locking issues. For mixed-vendor environments, consult device documentation for any specific module compatibility settings or required firmware levels.
