8/16/20 System DDF Digital Distribution Unit With ConnectorsUS$ 5.00 - 5.00MOQ: 1000 Units
This Digital Distribution Frame (DDF)as Gold-plated coaxial connectors with low contact resistance.
75ohm/120ohm impedance convert MPX610-C Digital Distribution Frame is a distribution device between digital multi-use device and switch to finish the matcheing and converting of the side impedance of distrivution device. It is suitable for 2Mbps connection between digital terminals or switches and digital equipment,that is coaxial cable on one side and twisted-pair ABS on the other side.
Modular structures ,adopting 75-ohm/120 ohms convert units to make installation,operation and expanding the capacity convenient.
Adopting coaxial socket,the end connects with coaxial plug for flexible distribution,wire adjusting and exchange,and using Y-shaped plug with test interface for convenient test.
Open structure ,cabling inside and wire adjusting can be done in all directions.
Adoptiong the rhombus nuts for conncetion of the units with the frame without drilling.
The quantity of units can be decided freely up to full capacity according to requirements of the customers.
The units can rotate 90"for convenient operation & maintenance
Perfect grounding system.
