The Multimode Accessory Kit for LinkXpert SQ from Softing IT Networks is a pre-configured set specifically developed for use with the LinkXpert SQ network analyzer. It enables fast and reliable execution of network tests in multimode fiber networks, particularly in environments based on 1000Base-SX technology. The kit is not compatible with the LinkXpert M3 and must be used exclusively in conjunction with the LinkXpert SQ.

Applications
This accessory kit is designed for use in local area networks (LAN) utilizing multimode glass fiber cables. It is particularly suitable for the installation, maintenance, and diagnosis of network infrastructures where connections are made at a wavelength of 850 nm. The components are suitable for use in data centers, office buildings, or industrial environments where precise analysis of fiber links is required.

Functions and Equipment in Detail
The kit includes a 1G SFP module with an 850 nm wavelength, supporting the 1000Base-SX standard. This module enables data transmission over multimode fibers with a range typically up to 550 meters, depending on cable quality. Additionally, two duplex multimode cables are included: one LC-LC cable and one LC-SC cable, both in OM4 quality and each with a length of 2 meters. These cables are designed for high data rates and support transmission of 10 Gbit/s over short distances. The cables are equipped with LC and SC connectors, which are widely used in IT infrastructure.

For testing and validating fiber links, two loopback connectors are included, one for LC and one for SC connections. These allow checking signal transmission within the local network without requiring an external connection. For maintenance and cleaning of optical connectors, two cleaning pens are included, one for LC and one for SC connectors. Cleaning is crucial for stable and error-free signal transmission.

Technology Explained Simply
The 1G SFP module operates in multimode mode at a wavelength of 850 nm, which is typical for use in short to medium distances within buildings or between server rooms. The OM4 cables offer high bandwidth and are designed for use in modern networks requiring high data rates. The loopback connectors serve as feedback elements to check the integrity of fiber links. The cleaning pens ensure that optical contacts remain clean, which is essential for minimal signal loss and high signal quality.

Compatibility and Accessories
The kit is exclusively intended for the LinkXpert SQ from Softing IT Networks. It is not suitable for other models such as the LinkXpert M3. The included components are tailored to the requirements of the LinkXpert SQ and ensure optimal interaction between the device and the fiber links. The cables and connectors are standardized and can be connected to other devices supporting the same connector types (LC, SC) and fiber types (OM4).

Installation and Mounting
Installation is performed by simply inserting the SFP module into the corresponding slot of the LinkXpert SQ. The cables are connected to the fiber links, ensuring the correct connector type (LC or SC) is selected. The loopback connectors are attached to the ends of the fiber links to test signal transmission. The cleaning pens are used before and after connecting the connectors to remove any contamination.

Operational Advantages
The accessory kit reduces preparation time for network tests, as all necessary components are pre-configured and bundled together. The use of OM4 cables and 1000Base-SX modules ensures high transmission quality. The loopback connectors enable quick diagnosis, and the cleaning pens ensure clean connections, reducing error rates during testing. The components are packaged in a soft bag, facilitating transport and storage.
