This product is an LWL patch cable from the brand Synergy 21, manufacturer's number S215506, designed for use in indoor network infrastructures. It is a duplex cable with a cable length of 40 meters, designed for connecting multimode fiber optic components. The fiber type corresponds to the OM5 standard with a core diameter of 50/125 µm, enabling high bandwidth and good transmission performance over short to medium distances. The cable is designed for indoor use and features a halogen-free (LSZH) insulation, which ensures low smoke and toxicity development in case of fire. The cable color is lime green, enabling visual differentiation from other cables in the rack or network room.

Applications
This patch cable is intended for use in structured cabling systems in the field of data communication, particularly in server rooms, data centers, and network distribution cabinets. It is suitable for connecting LWL ports on switches, routers, patch panels, or other network devices equipped with LC connectors. The cable length of 4len meters makes it especially suitable for longer connections within a building, for example, between different server racks or between a patch panel and a network device in the same room.

Functions and Equipment in Detail
LC/UPC connectors are mounted at both ends of the cable, where UPC stands for a flat polish (flat finish), ensuring low reflection and high signal quality. The connectors are lime green, contributing to visual identification. The fiber is duplex, meaning two fibers per cable, enabling bidirectional data transmission. The conductor diameter is 2 mm, ensuring stable mechanical guidance and a minimum bending radius of at least 7.5 mm. The cable is packaged in a blister pack from the brand Synergy 21, protecting the cable from damage and enabling clean storage.

Technology Explained Simply
The OM5 fiber type is specifically developed for use with wavelength division multiplexing (WDM) technologies, particularly for transmission in the 850 nm range. This enables higher data rates and better performance in modern networks designed for 10 Gbit/s and beyond. The use of LC connectors provides a compact form factor, optimally saving space in modern 48,3 cm ( 19 inch ) racks and patch panels. The UPC optics ensure low insertion loss and high return loss, enhancing signal quality. The halogen-free insulation is a safety feature that minimizes smoke development and reduces the risk of toxic gases in case of fire.

Compatibility and Accessories
The cable is compatible with all devices supporting LC/UPC connectors for multimode fiber optics. It can be combined with other products from the brand Synergy 21, such as LWL couplers (LC female/LC female, 50/125 µm, OM5, lime green, duplex), fiber cleaning pens, fiber cleavers, stripping tools, or carrying cases for LWL accessories. LWL patch panels with LC duplex sockets (e.g., 24xLC, 48,3 cm ( 19 inch )/1HE) are also suitable for integrating the cable into existing infrastructures. The use of cable organizers, Velcro tape, or cable ties supports orderly cabling and prevents mechanical stress.

Installation and Mounting
Installation is performed by simply inserting the LC connectors into the corresponding sockets of the network devices. The connectors are equipped with a clip ensuring secure locking. The cable length of 40 meters requires careful planning of the cabling to avoid unnecessary bends and tensile stress. The minimum bending radius of 7.5 mm must be maintained to ensure fiber integrity. The use of cable holders or cable organizers is recommended to route the cable properly and minimize mechanical stress.

Advantages in Operation
The patch cable provides a reliable and high-performance connection for multimode fiber optic applications. The use of OM5 fibers enables high bandwidth and good performance in modern networks. The lime green color facilitates identification in the rack. The halogen-free insulation increases safety during operation. The LC connectors are compact and universally applicable, simplifying integration into existing infrastructures. The blister packaging protects the cable from damage and ensures clean storage and presentation.
