Keystone module DELOCK 87192 — LC to LC duplex, colours Green/Grey/White, 60.1×59.4×21.6 mm

DELOCK 87192 keystone module is an LC-to-LC duplex fiber adapter intended for panel and patching applications. The compact adapter accepts LC duplex connectors on both sides to provide a secure optical connection. Its outer dimensions (60.1 × 59.4 × 21.6 mm) and keystone-compatible housing make it suitable for standard keystone wall plates, patch panels and customized enclosures. The module is available in green, grey and white colour options and is supplied as a single unit in protective packaging. The device also includes a small labelling field for identification and can be mounted on a 35 mm DIN rail for flexible installation.

Advantages

The adapter provides a reliable LC-to-LC duplex connection in a space-saving keystone form factor, enabling easy insertion into keystone cutouts without additional mounting hardware. Colour options facilitate visual identification of fiber lines or ports. The integrated labelling field supports clear port marking, and the DIN rail compatibility adds installation versatility for racks or distribution modules. The design supports secure alignment of LC connectors to maintain optical performance.

Suitable for

• Patch panels and keystone wall plates
• Fiber distribution boxes and small custom housings
• Field or lab installations requiring DIN rail mounting
• Environments where colour-coded fibre connections are used

How to use

Insert the DELOCK keystone module into a compatible keystone cutout on a wall plate, patch panel or custom enclosure until it snaps into place. For DIN rail installations, attach the module to a 35 mm wide rail using the dedicated mounting feature. Connect LC duplex fiber connectors on both sides, ensuring ferrules are clean and aligned before mating. Use the labelling field to mark the port according to your site coding scheme. For disconnection, carefully pull the LC connector boot without twisting to avoid stress on the fibre.

Recommendations

Clean LC connector endfaces with appropriate fiber cleaning tools before each connection to maintain low insertion loss. Avoid bending fibers beyond their specified minimum bend radius and secure cabling to prevent strain. Use the colour coding to maintain consistent network documentation and replace the module if physical damage to the housing or coupler is observed.
