What is a 100 Pair LSA Disconnection Block?
DESCRIPTIONS
100 pairs LSA disconnection block (TP-1418-100A) 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. In addition to protection of personnel and equipment against over-voltage disturbances, the terminal blocks support quality inspection and diagnostic processes.
Normally the 100 pairs disconnection blocks are used on the vertical side of the Main Distribution Frame (MDF), which is used for the termination between external lines and jumper wires. It consists of 10 pieces 10-pair disconnection modules. The block is suitable for xDSL circuit. Also the blocks are used in Cross Connection Cabinets (CCC), Distribution Point (DP) boxes.
Our 1 pair MDF protector (TP-1501-1EGP) and 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 and over-current. The disconnection block also known as terminal block, tag block or distribution block.
MAIN FEATURES
- High-Density Capacity: Supports 100 copper pairs, allowing large-scale line management in a single block. Its high-density design reduces frame clutter and simplifies network expansion, providing efficiency in both installation and future upgrades.
- Disconnection Functionality: Enables safe and precise isolation of individual lines for testing, maintenance, or troubleshooting without affecting other connected circuits, minimizing downtime and operational risks.
- LSA IDC Technology: Each connection point uses gas-tight, vibration-resistant insulation displacement contacts. Technicians can terminate wires without stripping insulation, soldering, or screws, ensuring a rapid, reliable, and long-lasting connection.
- Integrated Label Holder: Provides a secure, transparent space for labeling all pairs. Clear labels reduce errors, improve traceability, and simplify network documentation for technicians during maintenance or expansions.
- Integrated Earth Wire: Offers a reliable grounding path to protect connected lines from electrical surges, voltage spikes, or electromagnetic interference, enhancing safety and signal integrity.
- Surge Protection Ready: Compatible with external surge protection modules to provide additional defense against lightning strikes or power fluctuations, ensuring service continuity.
