Digital Distribution Frame (DDF)
Product Name: Digital Distribution Frame (DDF)Model Number: MPX241Place of Origin: ChinaThis equipment is used for distribution and communication of digital terminalequipment or programmable exchanger whose transmission rate is within 2 -155Mb/s. With the function of dispatching, transferring and testing for thecircuits, it is convenient to use and maintain, flexible to meet the needs ofchanges of business. It is one of the necessary facilities for digitaltransmission system and programmable exchange.Features:1) The coaxial connector adopts the gold plating process, which effectivelyensures its surface compactness and results in guaranteed contactresistance and abrasion resistance2) Individual shelf, which could rotate or lock down, quick installation,facilitates operation and maintenance3) Enough operation space for cabling, tidy and beautiful4) Perfect grounding device facilitates operation and maintenanceTechnical specification:1) Characteristic impedance: 75Ω2) Data rates: 2Mb/s, 8Mb/s, 34Mb/s, 140Mb/s, 155Mb/s3) Contact resistance: outer conductor ≤2.5MΩ inner conductor ≤10MΩ4) Insulation resistance: >1,000MΩ (5,000V DC)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: >50N10) Connection life span:≥1,000 times
