Product Description
This equipment is used for distribution and communication of digital terminal
equipment or programmable exchanger whose transmission rate is within 2 -
155Mb/s. With the function of dispatching, transferring and testing for the
circuits, it is convenient to use and maintain, flexible to meet the needs of
changes of business. It is one of the necessary facilities for digital
transmission system and programmable exchange.
Features:
1) The coaxial connector adopts the gold plating process, which effectively
ensures its surface compactness and results in guaranteed contact
resistance and abrasion resistance.
2) Individual shelf, which could rotate or lock down, quick installation,
facilitates operation and maintenance.
3) Enough operation space for cabling, tidy and beautiful.
4) Perfect grounding device facilitates operation and maintenance.
Technical specification:
1) Characteristic impedance: 75ohm
2) Data rates: 2Mb/s, 8Mb/s, 34Mb/s, 140Mb/s, 155Mb/s
3) Contact resistance: outer conductor ≤2.5mohm; inner conductor ≤10mohm
4) Insulation resistance: >1,000mohm (5,000VDC)
5) Dielectric strength: ≥1,000V (50Hz AC 1min, no spark-over and flying arc)
6) Cross-talk protection degree: ≥70dB (50KHz - 210MHz)
7) Insertion loss: ≤0.3dB (50KHz - 210MHz)
8) Return loss: ≥(50KHz - 210MHz)
9) Pulling strength: >50N
10) Connection life span:≥1,000 times
