RJ-45 Connector ROLINE 21173106 Black Female/Female

The ROLINE 21173106 Black Female/Female RJ-45 connector is a compact inline coupler for joining two Ethernet cables with RJ-45 plugs. Designed for simple extension or temporary linking of network cables, this black adapter provides a female-to-female connection in a small form factor that is suitable for patch panels, wall plates and cable assemblies where space is limited.

Advantages

This female-to-female RJ-45 connector offers a compact and lightweight solution for extending Ethernet runs without re-terminating cables. Its molded housing ensures consistent alignment of plug contacts for reliable signal transfer. The black finish provides a neutral appearance that blends with standard networking equipment and cabling. With minimal depth and narrow width, the connector is easy to place in tight spaces and simple to handle during installation or temporary setups.

Suitable for

• Extending existing Ethernet cables without cutting or re-terminating
• Temporary network connections in offices, workshops or test environments
• Connecting two patch cords behind equipment racks or in wall plate installations
• Quick replacements for a damaged or missing coupler in a cabling run

Key specifications

• Connector type: RJ-45 female to RJ-45 female
• Colour: Black
• Weight: approximately 6.3 g
• Width: 17.4 mm
• Depth: 36 mm
• Housing: compact molded design for cable alignment

How to use

Insert the RJ-45 plug of the first Ethernet cable into one side of the coupler until it clicks, then insert the RJ-45 plug of the second cable into the opposite side. Ensure plugs are fully seated to maintain contact integrity. Use the connector for in-line extensions, temporary joins, or to connect patch cords when reorganizing network layouts. Remove by pressing the plug latch and pulling the plug straight out to avoid damaging contacts or the housing.

Usage recommendations

Use in environments where a simple mechanical join is sufficient; for permanent installations or runs requiring optimal signal performance over long distances, consider using a single continuous, properly terminated cable. Avoid exposing the coupler to excessive mechanical strain, moisture, or corrosive environments to maintain contact reliability.
