Features
Product colour	Blue

The product is an LWL duplex connector from manufacturer Intellinet, type 514736, in blue color. It serves as a coupling for connecting two single-mode or multimode optical connectors in SC format. The coupling enables a secure and stable connection between two LWL connectors in duplex mode, where two fibers (one for transmission, one for reception) are connected via a common adapter. The metallic sleeve provides mechanical stability and protects the optical fibers from mechanical stress. The blue color indicates use for multimode systems, which is common practice to visually distinguish fiber types.

Applications
This connector is used in network infrastructures where a fixed, permanent connection between two LWL connectors is required. This includes, among other things, connecting patch cables in server rooms, linking network devices such as switches or routers to LWL backbones, and integration into distribution boxes or patch panels. Use in duplex configurations is typical for Ethernet transmissions over fiber optic, especially in 100BASE-FX or 1000BASE-SX networks that use multimode fibers.

Functions and Features in Detail
The coupling is designed as a duplex adapter, meaning it supports two individual SC connectors simultaneously. The metallic sleeve offers high mechanical protection and ensures precise alignment of the fibers. The blue color is standard for multimode systems, simplifying identification and cabling in the network. The construction is designed for use in enclosed distributors and patch panels, where a compact and robust connection is required.

Technology Explained Simply
An SC/SC duplex adapter connects two SC connectors, with each connector transmitting one optical fiber. In duplex mode, two fibers are connected in parallel to enable bidirectional data transmission. The metallic sleeve protects the sensitive fibers from mechanical stress such as pressure or bending. The blue color is a visual indicator for multimode systems, typically used for shorter distances within buildings or data centers.

Compatibility and Accessories
The adapter is compatible with SC connectors in duplex format designed for multimode systems. It can be connected to standard LWL patch cables that also feature SC connectors. Its intended use is in combination with patch panels, distribution boxes, or network devices that support SC connectors.

Installation and Mounting
Mounting is done by simply inserting the two SC connectors into the corresponding openings of the coupling. The metallic sleeve ensures a secure and precise alignment. The coupling is designed for use in enclosed distributors or patch panels, with no special tools or additional mounting components required. Installation is done without additional fastening elements, as the plug connection itself ensures mechanical stability.

Operational Advantages
The coupling provides a reliable and mechanically stable connection for multimode LWL systems. The metallic sleeve increases service life and protects the fibers from damage. The blue color simplifies identification and cabling in the network, making maintenance and fault diagnosis easier. The duplex design enables bidirectional data transmission without additional components, reducing network setup costs.
