The RED LWL-Duplex patch cable type 2716-10-0006 is a high-quality fibre-optic patch cable for use in networks with multimode technology. It connects optical components in duplex format, with two fibres integrated into one cable to enable bidirectional data transmission. The cable is equipped with halogen-free sheathing (LSZH), which minimises the formation of toxic gases in the event of a fire and increases safety in enclosed spaces. The sheath colour Erika-Violet serves as visual identification and facilitates recognition in cable management. The fibre type multimode 50/125 µm is suitable for short to medium transmission distances in local area networks (LAN). The OM4 category enables high data rates and is designed for applications such as 10 Gigabit Ethernet over short distances. The operating temperature of -40 °C to +85 °C makes the cable suitable for use in indoor and outdoor environments, provided mechanical loads remain within standard limits.

Applications
This LWL-duplex patch cable is used in structured cabling systems, particularly in server rooms, data centres, and for connecting switches, routers, and other network devices. The OM4 category is intended for high-speed applications such as 10 GbE and 40 GbE over short distances. The halogen-free sheathing meets fire safety requirements in public and commercial spaces. The violet sheath colour supports cable management, as it is commonly used in practice for OM4 cables.

Functions and Equipment in Detail
The cable features two fibres in duplex format, each fitted with an SC connector. The connectors are equipped with end caps that protect against dust and contamination, extending the service life of the optical contacts. A duplex clip on each connector allows channel swapping, enabling cross-patching – a feature useful during network installation and maintenance. The insertion loss is 0.3 dB at 850 nm, ensuring high signal quality and minimal signal loss. The fibres are made of silicone, providing high flexibility and mechanical stability.

Technology Explained Simply
The multimode fibre with 50/125 µm enables light signal transmission across multiple modes, increasing bandwidth. The OM4 category is a standard for multimode fibres, supporting a maximum data rate of 10 Gbit/s over up to 150 metres. The halogen-free sheathing (LSZH) reduces the formation of toxic smoke gases in case of fire, which is particularly important in enclosed spaces such as server rooms or office buildings. The operating temperature range of -40 °C to +85 °C indicates that the cable operates reliably even under extreme environmental conditions, for example in basements or under direct sunlight.

Compatibility and Accessories
The cable is fitted with SC connectors, widely used in the IT and telecommunications industry. It is compatible with other SC connectors and can be used in standard network devices. As suitable accessories, the patch cable 151S1EOEO10E (SC-D/SC-D OM4, 1 m, OpDAT) is offered, which is also suitable for OM4 applications. Combining it with other OM4 cables enables consistent network cabling with high performance.

Installation and Mounting
Installation is carried out by simply inserting the SC connectors into the corresponding ports of the network devices. The end caps should be removed before installation and reattached after connection to keep the connectors clean. The duplex clip facilitates channel switching if a cross-connection is required. The cables are flexible and can be easily routed in cable ducts or on cable trays. The length of 1.0 m is suitable for short connections within server rooms or between adjacent devices.

Advantages in Operation
The cable provides reliable, high data transmission rates with minimal signal loss. The halogen-free sheathing increases safety in case of fire. The violet colour supports visual differentiation in cable management. The SC connectors with duplex clip allow flexible installations, even in complex patching scenarios. The operating temperature range of -40 °C to +85 °C ensures stable performance under various environmental conditions. The multimode fibre type 50/125 µm is optimised for use in modern LAN infrastructures.
