Keystone-moduuli DELOCK 87189 — LC – LC duplex, värit sininen/harmaa/valkoinen, 60,1×59,4×21,6 mm

The DELOCK 87189 keystone module is an LC-to-LC duplex fiber adapter designed for standardized keystone mounting in patch panels, wall plates and DIN rail installations. It provides a compact LC duplex coupling to join two LC fiber connectors reliably. The module is supplied in single-piece packaging and is available in blue, grey or white finishes, with a compact footprint of 60.1 × 59.4 × 21.6 mm and an integrated labelling field for identification.

Advantages

This keystone module offers a space-saving LC-to-LC duplex interface that supports simple fiber coupling in confined panel environments. The product is color-coded to assist in cable identification and is compatible with standardized keystone cutouts. Its durable construction allows repeated insertions and removal of LC connectors while preserving alignment accuracy. A built-in labelling field and the option to mount on a 35 mm DIN rail add installation flexibility.

Suitable for

• Fiber patch panels and wall plates where keystone modules are used
• DIN rail-mounted network enclosures and distribution frames
• FTTx deployments and LAN backbone fiber terminations
• Environments requiring compact LC duplex connections and color-coded identification

Key specifications

• Connector type: LC duplex to LC duplex coupling
• Mounting format: keystone module compatible with standard keystone ports
• Dimensions: 60.1 × 59.4 × 21.6 mm (width × height × depth)
• Color options: blue, grey, white
• Mounting option: compatible with 35 mm DIN rail attachment
• Additional feature: integrated labelling field for identification

How to use

Insert the keystone module into a compatible keystone opening in a patch panel or wall plate until it locks in place. If DIN rail mounting is preferred, engage the module on a 35 mm DIN rail according to the rail clip engagement. Connect LC fiber connectors by aligning and inserting each LC plug into the duplex coupler until a secure click is felt. Use the labelling field to mark the port function or fiber route for easier identification during maintenance.

Recommendations

Handle fiber connectors with care to avoid contamination of end faces; clean connectors before mating and use dust caps when ports are not in use. For best performance, follow standard fiber handling procedures and ensure proper strain relief for connected cables.
