The product is an LWL patch cable from the brand Synergy 21, manufacturer's number S215498, designed for use in indoor network infrastructures. It is a duplex patch cable with a cable length of 3 meters, designed for connecting multimode fiber optic devices. The fiber type corresponds to the OM5 standard with a core diameter of 50/125 µm, enabling high bandwidth and good signal transmission over short to medium distances. The cable is designed for indoor use and complies with the LSZH (halogen-free) category, ensuring reduced smoke and toxicity development in case of fire. The cable color is lime green, enabling visual differentiation from other cable types and aiding in better identification within network cabling.

Applications
This patch cable is suitable for use in structured cabling systems in offices, data centers, server rooms, and other indoor environments. It is typically used between LWL ports of switches, routers, servers, or patch panels to ensure stable and fast data transmission via fiber optic. The OM5 fiber is specifically designed for use with wavelength division multiplexing (WDM) technologies and modern high-speed networks such as 100 Gigabit Ethernet over multimode fiber.

Functions and Features in Detail
LC/UPC connectors are mounted at both ends of the cable, featuring a flat polish (UPC). This connector type is standardized and enables a precise and secure optical connection. The connectors are colored lime green, aiding in visual identification. The fiber is protected with heat shrink tubing, providing mechanical stabilization and protection against mechanical stress. The cable jacket has an outer diameter of 2 mm, allowing for flexible handling and easy installation in cable ducts or cable trees.

Technology Explained Simply
The OM5 fiber is a multimode fiber optimized for high data rates over short to medium distances. The core diameter of 50 µm allows for good light guidance, while the 125 µm cladding ensures optical isolation. The designation OM5 refers to the specific classification for multimode fibers suitable for use with parallel optical systems (e.g., 40G/100G). The UPC coating (Ultra Physical Contact) ensures low reflection at the connector interface, improving signal quality. The minimum bending radius of 7.5 mm (according to datasheet) ensures the cable can be bent without damaging the fiber, which is important during installation in confined spaces.

Compatibility and Accessories
The cable is compatible with all devices supporting LC connectors for multimode fiber. It can be combined with other LWL components such as patch panels (e.g., S216298V3 or S216299V3) or LWL couplers (e.g., S215508 or S215509) to build a structured cabling system. For maintenance and testing, accessories such as an LWL fiber checker (S215491V2) or a fiber optic cleaver (S215662) are available for fault diagnosis and installation. The use of cable organizers (e.g., spiral organizers) or cable ties (e.g., S215696) supports orderly routing and storage of the cable.

Installation and Mounting
Installation is performed by simply inserting the LC connectors into the corresponding sockets of the devices. The connectors feature a clip for secure locking. During installation, the minimum bending radius of 7.5 mm must be observed to avoid damaging the fiber. The cable is delivered in a blister pack from Synergy 21, ensuring protection during transport and storage.

Operational Advantages
The patch cable provides reliable and stable data transmission with high bandwidth. The use of OM5 fiber enables compatibility with modern networking technologies. The halogen-free construction (LSZH) enhances safety in case of fire. The lime green color facilitates identification and management of cabling. The robust construction with heat shrink tubing and LC connectors ensures long service life and low maintenance requirements.
