## Summary description

The BlueOptics AXSK-CSFP-LR-BO is a fiber optic SFP transceiver module with a maximum data transfer rate of 1250 Mbit/s. It features a durable metal housing and a mean time between failures (MTBF) of 1,000,000 hours, ensuring reliability. Weighing only 20 g, it is lightweight and suitable for various networking applications.

## Long description

The BlueOptics AXSK-CSFP-LR-BO is an SFP fiber optic transceiver module designed for 1.25 Gbit/s (1250 Mbit/s) networks. Housed in a durable metal enclosure and weighing approximately 20 g, this silver-coloured SFP module follows MSA standards for physical interoperability and is intended for single-mode fiber links using an LC duplex connector. The module supports long-reach optical transmission and is specified with a high MTBF for continuous operation in network equipment.
Advantages
The module provides a compact SFP form factor with a metal housing that contributes to mechanical robustness and thermal dissipation. With a maximum data rate of 1250 Mbit/s and design compatibility to common 1000BASE-LX implementations, it supports simultaneous transmit and receive operation via LC duplex fibre. The high MTBF rating indicates extended operational life, while the lightweight design simplifies handling and installation in switches, routers or other SFP-capable devices.
Suitable for
Single-mode fiber uplinks and backbone connections
Switch-to-switch or switch-to-router links up to long-reach distances
Data centre interconnects and enterprise campus networks
Applications requiring MSA-compliant SFP modules with LC duplex connector
Key specifications
Interface type: SFP (small form-factor pluggable)
Maximum data transfer rate: 1250 Mbit/s (1.25 Gbit/s)
Optical standard: compatible with 1000BASE-LX single-mode operation (LC duplex)
Transmitter/receiver wavelength: 1310 nm (TX/RX for single-mode links)
Housing material: metal (silver finish) for durability and heat dissipation
Typical weight: 0.02 kg
High reliability design with MTBF around 1,000,000 hours
How to use
Install the BlueOptics SFP module into any compatible SFP slot in accordance with your device manufacturer’s insertion procedure: power down or follow hot-swap guidance for the host device, align the SFP module with the slot and push until it clicks into place, then secure any retention mechanism. Connect LC duplex single-mode fiber patch cords to the transceiver’s connectors, observing correct TX/RX orientation. Verify link status and configure the host interface for 1 Gbit/s operation if required. Use vendor-provided diagnostics or host management tools to confirm signal levels and link integrity.
Usage recommendations
For optimal performance, use high-quality single-mode LC duplex patch cords, ensure clean connector endfaces, and confirm that the host device supports 1000BASE-LX SFP modules. If available, enable digital diagnostic monitoring (DDM/DOM) on the host to monitor real-time parameters such as optical power and temperature. Follow ESD precautions during handling and store spare modules in protective packaging.
