BERT428 100G BERT 誤碼率測(cè)試儀

BERT428 100G BERT 誤碼率測(cè)試儀

LUCEO BERT428是由速率從2Gbps到28.05Gbps的4通道高速碼型發(fā)生模塊組成及25Gbps到28.05Gbps的4通道誤碼檢測(cè)模塊，模塊可以串聯(lián)時(shí)鐘工作，因此它是100Gb/s和未來400Gb/s應(yīng)用的理想測(cè)試解決方案。

BERT428 is 100Gb/s BERT. EPG428 is an Electrical Pattern Generator module that plugs into the PARALLEX? Chassis. EPG428 can generate 4 channel electrical data from 1 Gb/s up to 29 Gb/s continuously. EED428 is an Electrical Error Detector module that plugs into the PARALLEX? Chassis. EED428 can check 4 channels electrical data from 22.0 - 28.2Gbps and 8.5Gb/s – 14.1Gb/s.

Note:

  1. Output of clock signal is used for daisy chaining additional modules. Maximum daisy chain length is four.
  2. RJ measured with CLK pattern. Depends on applied clock signal (measured with CLK20-2 Module, RJ=200fs)
  3. Measured at 1GBd at the static High/ Low level of the signal with de-emphasis=0dB.
    The eye height at higher data rates might differ.

Note:

  1. Apply full rate clock for low data rate range and half rate clock for high data rate range.
  2. Additional DR/40 CLK output installed
  3. BER of better than 1E-12 can only be achieved if at least the min. input voltage level is applied
  4. Minimum input voltage to guarantee error free detection (BER < 10-12) at PRBS31. The input sensitivity of??????????
    the module will be better for input signals with lower bandwidth, e.g. PRBS7.
