The Singlemode accessory kit for LinkXpert SQ by Softing IT Networks is a specific add-on package for using the LinkXpert SQ network analyzer in singlemode fiber applications. It extends the functionality of the device for diagnosing and analyzing singlemode optical connections, particularly in high-speed environments such as 10G Ethernet. The kit is designed exclusively for the LinkXpert SQ and is not compatible with other models such as the LinkXpert M3.

Applications
This accessory kit is intended for technicians and network installers who inspect and maintain singlemode optical systems in corporate networks, data centers, or industrial environments. The components enable signal integrity testing, fault localization, and performance testing on singlemode fibers, particularly in the 10GBaseLR standard. The use of OS2 fibers and 1310 nm wavelength makes the kit suitable for long distances with low attenuation, typical for backbone connections.

Functions and Equipment in Detail
The kit includes a 10G SFP module with 1310 nm wavelength, supporting the 10GBaseLR standard. This module enables connection of the LinkXpert SQ to singlemode fiber infrastructures and serves as a transmitter/receiver for signal transmission. Additionally, two duplex cables are included: one LC-LC and one LC-SC cable, both with OS2 fiber and a length of 2 meters. These cables are used to connect the device to the fiber link under test. The loopback connectors in LC and SC configurations allow simulation of a feedback loop to test signal quality and port functionality. Two cleaning pens, one for LC and one for SC connectors, ensure clean and interference-free connections, which is crucial for accurate measurement results. A soft bag is provided for protection and storage of the components.

Technology Explained Simply
The 10G SFP module operates in singlemode mode at a wavelength of 1310 nm, providing high reach and low signal attenuation. The OS2 fiber used in the cables is optimized for long distances and is standard in professional networks. The duplex configuration of the cables means two fibers are laid in parallel to enable bidirectional data transmission. The loopback connectors simulate signal return to check connection integrity without requiring a physical connection to the other end. The cleaning pens are specifically designed for optical connectors to remove particles or contamination that could cause signal loss.

Compatibility and Accessories
The kit is designed exclusively for the LinkXpert SQ. The components are not suitable for other models such as the LinkXpert M3. The included cables and connectors are designed for standard connectors in IT infrastructure, with LC and SC connectors being the most commonly used types in singlemode applications. The use of OS2 fibers ensures compatibility with existing high-performance networks.

Installation and Mounting
Installation is performed by simply inserting the SFP modules into the corresponding port of the LinkXpert SQ. The cables are connected to the fiber link and the device. The loopback connectors are attached to the fiber connector to simulate feedback. The cleaning pens are used to clean the connectors before establishing the connection. The components are designed for quick and easy handling, without requiring additional tools.

Operational Advantages
The accessory kit reduces preparation time for network analysis, as all necessary components for singlemode testing are included in one set. Compliance with standards such as 10GBaseLR and OS2 fiber ensures reliability of measurement results. The cleaning pens help minimize errors caused by contamination, increasing the accuracy of diagnostics. The soft bag protects sensitive optical components during transport and storage.
