Tham khảo tài liệu 'krone - white paper - zero bit error rate', công nghệ thông tin, quản trị mạng phục vụ nhu cầu học tập, nghiên cứu và làm việc hiệu quả | WHITE PAPER ZERO BIT ERROR RATE On Data Throughput in Structured Cabling Systems Released by KRONE Australia Asia Pacific Test Laboratory (Certified by Underwriters Laboratories) February, 2001 ZERO BIT ERROR RATE Cabling infrastructure providers are following KRONE’s lead regarding the importance of having the lowest bit error rate possible. This white paper confirms that zero bit error rate is a practical reality that Network managers can rely on. More and more network managers are demanding of the signal. Events such as noise, impulses due to that their networks operate to their maximum switching surge or lightning, transmission equipment potential, rather than merely operate as a standards- fault plus others can all cause a bit error (eg. it is the compliant solution. Downtime or a slowdown in reception of 0 when 1 was transmitted or vice versa). network performance can be crippling to an The Bit Error Rate (BER) is a measure of how often organisation in today’s global e-commerce these errors occur. environment. Statistical Method Some measurement techniques are based on statistical The network cabling infrastructure must be able to analysis which predict the number of bit errors with a support an enterprise’s increasing rates of data certain degree of accuracy using common statistical transmission now and in the future. It’s imperative distribution methods. For example: that mission-critical information which is transmitted in P (e)_ packages of bits is delivered immediately, without Log M < Pb (e) < P (e) costly delays. Bit Error Rate (BER) testing is one way of 2 measuring a network’s performance - of seeing how Pb(e) is bit error probability which equals BER. quickly and efficiently information is delivered from P(e) is the probability that a waveform is detected sender to receiver. Zero Bit Error Rate (ZBER) has been incorrectly. the goal that now is a practical reality, thanks to M is the number of discrete signal levels (eg 3 for KRONE’s TrueNet .
