## Summary description

The BlueOptics 25G-ER-SFP40KM-BO is a fiber optic SFP28 transceiver module designed for high-speed data transfer with a maximum rate of 25000 Mbit/s. It features a silver color, weighs only 20 g, and has a mean time between failures (MTBF) of 1000000 hours, ensuring reliability and longevity in network applications.

## Long description

The BlueOptics 25G-ER-SFP40KM-BO is an SFP28 fiber optic transceiver module engineered for high-speed network links. Supporting a maximum data rate of 25,000 Mbit/s and single-mode fiber connections via an LC connector, this compact silver module is intended for long-reach applications up to 40,000 meters. With a lightweight design of 20 g and a specified MTBF of 1,000,000 hours, it is suitable for integration into switches, routers and media converters that accept SFP28 form-factor transceivers.
Advantages
The module provides a high aggregate throughput of 25 Gbit/s in an industry-standard SFP28 package, enabling dense port configurations and straightforward upgrades from lower-speed SFPs where supported. Its LC fiber interface and single-mode reach make it appropriate for extended point-to-point links. The compact silver housing and low weight simplify handling and installation, while the long MTBF indicates extended operational reliability in continuous network environments.
Suitable for
 Long-distance single-mode fiber links between data centers and core network nodes
 High-speed uplinks in aggregation switches and routers
 Upgrade paths from 10G to 25G-capable equipment with SFP28 slots
 Use in media converters and transponder devices requiring LC connectors
Key specifications
 Maximum data transfer rate: 25,000 Mbit/s
 Maximum transfer distance: 40,000 m (single-mode fiber)
 Fiber optic connector type: LC
 Interface form factor: SFP28 (25G)
 Physical colour: Silver
 Weight: 0.02 kg
 Reliability (MTBF): 1,000,000 hours
How to use
Ensure the host device supports SFP28 transceivers and 25 Gbit/s operation before installation. Power down or follow hot-swap procedures recommended by the equipment manufacturer, then insert the BlueOptics SFP28 module into an available SFP28 slot until it seats securely. Connect a single-mode fiber cable with compatible LC connectors, observe correct transmit/receive orientation, and verify link status via the host device LEDs or management interface. Configure any required interface parameters such as speed, duplex or FEC in the network equipment as needed.
Usage recommendations
Install and remove the transceiver using antistatic precautions, avoid touching the fiber endfaces, and keep protective dust caps on unused ports. Use single-mode fiber rated for long-reach transmission and verify optical power budget compatibility between link endpoints to ensure reliable 40 km performance.
