1 Pair Terminal Block, VX 5 Point Connection Module, STB Module, Subscriber Terminal Block

Summit Telecom is China leading manufacturer provides 1 Pair Terminal Block, VX 5 Point Connection Module, STB Module, etc. in outside plant.
  • Description:
1. Item Code: ST VX-MD
2. 1 Pair Terminal Block is designed for mounting on a standard DIN rail and can therefore be mounted in a variety of housings in whatever quantities are required. The small footprint (2 cm wide) ensures a compact product.
3. 1 Pair Terminal Block provides a connection point between an exchange-side cable pair and a distribution pair.
4. VX 5 Point Connection Module incorporates a 5-point plug in module to provide continuity and a range of other options. Removal of the plug-in module does not disturb wire connections but makes contacts to them available for testing to both sides of the network.
5. VX 5 Point Connection Module (STB Module) is especially recommended for
a) Outdoor connections where the environmental conditions are extremely aggressive.
b) Terminations where user development characteristics require future flexibility in terms of the type of protection or filtering capabilities.
