Shop 110 and 66 cross-connect systems for organizing, terminating and distributing copper voice and data cabling. Wallco offers wiring blocks, connector clips, rack-mount kits and related cross-connect hardware for telecommunications, structured-cabling and equipment-room installations.
Compare products by block type, pair capacity, mounting configuration, connector arrangement and application. Select components that match the cabling system and cross-connect hardware already installed at your facility.
110 and 66 cross-connect systems provide organized termination and distribution points for multi-pair copper cabling. These systems are commonly used in telecommunications rooms, equipment spaces and structured-cabling installations where large numbers of copper pairs need to be terminated, identified and interconnected.
Unlike conventional RJ45 patch panels, cross-connect blocks expose groups of individual cable pairs so connections can be organized according to the requirements of the voice, data or communications system. The appropriate block system depends on the installed infrastructure, pair capacity, mounting method and type of connecting hardware required.
110-style wiring blocks are used to terminate and cross-connect twisted-pair copper cabling. Depending on the product, a block may be designed for wall mounting, rack mounting or installation as part of a complete wiring-block kit.
110 systems can include the base wiring block, connecting clips, cable-management hardware, mounting components and other accessories required to complete the installation.
When selecting a 110 block, verify the total pair capacity and the type and quantity of connecting clips required by the application.
66-style blocks remain common in existing telecommunications and voice-distribution installations. They provide rows of termination points for connecting and cross-connecting copper pairs and may be used with compatible bridging, connector and mounting hardware.
When maintaining an existing 66-block installation, identify the block configuration and connected cabling before ordering replacement components. Different applications can use different arrangements of terminals and connectorized interfaces.
The choice between a 110 and 66 cross-connect system is often determined by the infrastructure already installed and the type of communications system being supported.
When replacing components in an existing installation, maintaining compatibility with the current block style is usually the most straightforward approach. During new installations or major upgrades, the cabling design, pair requirements and intended communications application should be evaluated before selecting the termination system.
Cross-connect systems are frequently described by the number of copper pairs they can terminate. The required capacity depends on the number of circuits or cable pairs entering the termination point.
Before selecting a block or kit, determine the total pair count required by the current installation and consider reasonable capacity for future additions. Larger installations may use multiple blocks or rack-mounted assemblies to organize hundreds of pairs.
Wall-mounted wiring blocks are commonly installed on telecommunications backboards or other suitable surfaces. Rack-mounted systems can integrate cross-connect hardware into the same equipment racks used for patch panels, network equipment and cable management.
The best configuration depends on available space, cable routing and the existing telecommunications-room layout. For rack installations, verify the required rack width and vertical space before ordering.
A complete 110 cross-connect installation may require connecting clips, designation strips, cable managers and other accessories in addition to the base wiring block.
Connecting clips should match the wiring-block system and conductor arrangement specified for the installation. Accessories from one block family should not automatically be assumed to fit another system solely because both are described as 110-style components.
Some cross-connect products combine 110 or 66 termination hardware with prewired multi-pair connector assemblies. These products can provide a transition between field wiring and equipment using compatible multi-pair telecommunications interfaces.
When choosing a connectorized assembly, verify the block capacity, connector gender, number of connectors and cable configuration required by the equipment on the opposite side of the connection.
Cross-connect systems may be used in applications including:
Before ordering a 110 or 66 cross-connect component, identify the existing block style, pair capacity, mounting configuration and required accessories. If the system uses connectorized assemblies, verify the connector type and cable configuration as well.
For replacement projects, comparing the installed block, connecting clips and mounting hardware with the replacement product can help avoid compatibility problems.
