TAEPO - Your Professional Source for LSA Connection Block, Expert Chinese Manufacturing at Its Best!
What is a 100 pairs LSA Connection Block ?
DESCRIPTIONS
100 pairs LSA connection block (TP-1418-100B) are used for both voice and data networks in the central office, cabinets and in private networks applications. With their reliable IDC (Insulation Displacement Connection) contacts they are the interface between the truck cable and drop cables.
Normally the 100 pairs connection blocks are used on the horizontal side of the Main Distribution Frame (MDF), which is used for the termination between internal lines and jumper wires. It consists of 10 pieces 10-pair connection modules. The block is suitable for xDSL circuit. Also the blocks are used in Cross Connection Cabinets (CCC), Distribution Point (DP) boxes.
Our 10 pairs over-voltage protection magazine (TP-1502-10P3G) can be inserted into the block, with the function of protecting personnel and equipment against over voltage. The connection block also known as terminal block, tag block or distribution block.
MAIN FEATURES
- High-Density Capacity: Accommodates 100 copper pairs, allowing large-scale network consolidation into a single block. Its compact design maximizes frame space while keeping all connections accessible.
- Permanent Connection Design: Maintains uninterrupted electrical continuity for all pairs, ensuring consistent voice and data transmission without disconnection points.
- LSA Insulation Displacement Contacts: Provides tool-assisted, screw-free terminations that hold wires firmly in place, creating vibration-resistant and corrosion-proof connections.
- Low Contact Resistance: Maintains high signal quality across all pairs, reducing losses for xDSL and voice services, and supporting broadband applications reliably.
- Integrated Label Holder: Offers a clear, protected space for labeling each pair, simplifying identification, documentation, and future troubleshooting tasks.
- Integrated Earth Wire: Provides reliable grounding, protecting both the block and connected equipment from surges, static, and electromagnetic interference.
- Surge Protection Compatibility: Can be used with external surge protection modules, adding an extra layer of line defense against lightning or voltage spikes.
- Compact Modular Design: Organizes 100 pairs in a space-efficient format, allowing high-density installation without sacrificing accessibility.
- Quick and Reliable Installation: IDC technology enables fast termination with standard LSA punch-down tools, reducing installation time for large-scale deployments.
