HC-M106B DDF Digital Distribution Frame

  • Close cabinet
  • Open cabinet
  • Module unit

Application
The HC-M106B DDF digital distribution frame is designed for use in machine rooms as a distribution device that operates between digital multiplex equipment or between digital multiplex equipment and program controlled exchange devices. The transmission impedance of the distribution frame is 75Ω, and the transmission rate is between 2Mbit/s~155Mbit/s. These units provide dispatching, transferring, monitoring, and many other functions for the digital signal of the circuit group.

Technical performance
1. Working speed: 2~155Mbit/s
2. Transmission impedance: 75Ω
3. Crosstalk ratio between circuits: ≥70db(50khz～233mhz)
4. Insertion loss: ≤0.3db(50khz～233mhz)
5. Return loss: ≥18db(50khz～233mhz)
6. Contact resistance of the coaxial connector:
Outer conductor: ≤2.5mΩ
Increment after the mechanical endurance test: ≤2.5mΩ
Inter conductor: ≤10mΩ
Increment after the mechanical endurance test: ≤10mΩ
7. Insulation resistance: ≥1000MΩ (500VDC)
8. Pull-out force: ≥50N
