Subscriber Connector Unit STB Drop wire connection module
The VX connection modules are designed to provide easy, reliable and re-usable points of connection between distribution cable pairs and drop or service wires leading to subscriberÕs equipment.
In this application, connection blocks are installed in units of 5 up to a maximum of 25 on a polymer baseplate. Wire guides are fitted at each corner to organize drop wires.
Two terminals may be provided for connecting a pilot pair if required. A smaller, 5-pair version is also available.
The subscriber terminal block consists of a rectangular box base with a cover and two five-pole connection modules secured in a stainless steel plate.
The top and base are hinged together, and the top is easily removable to facilitate working in cramped conditions.
The cable grommets for wire entry and exit may be adjusted to conductor size and are also removable.
A metal screw is provided in the wire housing recesses to secure the grounding wire.
