This product is an LWL patch cable from the brand Synergy 21, manufacturer's number S216268, designed for use in indoor network infrastructures. It is a duplex patch cable with a cable length of 0.5 metres, designed for connecting multimode fibre optic components. The fibre type corresponds to the OM4 standard with a core diameter of 50/125 µm, enabling high bandwidth and transmission performance over short to medium distances. The cable construction is designed for indoor use, halogen-free (LSZH), and has a conductor diameter of 3.0 mm. The cable colour is Erika Violet, a colour code commonly used in fibre optic technology for multimode connections.

Applications
This patch cable is intended for use in structured cabling systems in offices, data centres, or other indoor environments. It is used to connect network devices such as switches, routers, servers, or patch panels equipped with LC connectors. The OM4 fibre enables data transmission rates up to 10 Gbit/s over distances up to 150 metres, with the exact range depending on the technology used and signal quality. Its use in indoor environments is supported by the halogen-free insulation and low fire hazard.

Functions and Features in Detail
LC/UPC connectors are mounted at both ends of the cable, where UPC stands for a flat polish, ensuring low reflection and high signal quality. The connectors are equipped with a white protective boot and a dust cap to protect the fibre end faces from contamination and damage. The connector interface is standardised, enabling a secure and repeatable connection. The cable colour Erika Violet serves as a visual identifier and facilitates identification in cable management.

Technology Explained Simply
The OM4 fibre is a multimode fibre that transmits multiple light modes simultaneously. This allows for higher data rates compared to singlemode fibres over shorter distances. The 50/125 µm geometry refers to the core and cladding diameter of the fibre. The halogen-free insulation (LSZH) reduces the formation of toxic gases in case of fire, which is important in enclosed spaces such as server rooms. The conductor diameter of 3.0 mm ensures sufficient mechanical stability and flexibility, with the cable having a minimum bending radius of 7.5 mm, enabling flexible installation.

Compatibility and Accessories
The cable is compatible with all devices supporting LC duplex connectors, including patch panels, switches, and servers. Suitable accessories include LWL couplers with LC sockets, also designed for 50/125 µm multimode OM4, as well as tools such as fibre cutters, stripping tools, and cleaning pens. These components support installation, maintenance, and testing of the connection. Additionally, cable ties and organisers are available to structure cable routing.

Installation and Mounting
Installation is performed by simply inserting the LC connectors into the corresponding sockets of the devices. The connectors are equipped with clips to ensure a secure locking mechanism. The cable length of 0.5 m is suitable for short connections within patch panels or between devices in close proximity. The halogen-free insulation and small bending radius facilitate routing in confined spaces.

Operational Advantages
The use of an OM4 patch cable provides high bandwidth and reliability for modern network applications. The Erika Violet colour supports cable management, and the LC/UPC connectors ensure a stable, low-reflection connection. The halogen-free design increases operational safety, especially in enclosed spaces. The combination of short length and high performance makes the cable ideal for use in server rooms and network centres.
