Fibre Optic Adapter LC quadruple VALUE 21.99.0660

The VALUE Fibre Optic Adapter LC quadruple (model 21.99.0660) is a compact multimode fiber coupling designed to connect or extend fiber optic cabling. It provides four LC sockets in a single housing, suitable for OM3 multimode fiber installations. The adapter comes in a high-quality aqua plastic housing with phosphor bronze guide sleeves for the ferrules, and is intended for cost-effective, space-saving fiber connections in rack or patch panel environments.

Advantages

This LC quadruple adapter offers a compact design that fits four LC connectors in one module, enabling efficient space utilization. The phosphor bronze (PB) guide sleeves ensure stable alignment of ferrules and consistent optical performance. The molded aqua plastic housing provides a durable and industry-standard color coding for multimode connections. The coupling is easy to install into front panel cutouts designed for duplex SC, supporting fast deployment and extension of multimode fiber runs.

How to use

Install the adapter into a compatible front panel or patch panel cutout that accepts duplex SC-sized modules, ensuring it snaps or secures into place per the panel design. Insert LC multimode fiber connectors into the LC sockets until they click, observing correct orientation and polarity for your link. For cable extension, connect the opposite cable ends to the corresponding network equipment or patchcords. Follow standard fiber handling practices—avoid bending beyond the specified radius and keep connector endfaces clean to maintain low insertion loss.

Usage recommendations

Use with OM3 multimode fiber only; do not use with single-mode fiber. Clean connectors before insertion and use dust caps when not connected. Verify compatibility with your panel cutouts (fits front panel cutouts for duplex SC) and follow rack mounting procedures to avoid mechanical stress on the adapter and connected fibers.
