Abstract
Next generation fiber-optic transmission systems adopt new line codes for considerably simplifying clock recovery . The major concern in implementing such new transmission schemes was the influence of jitter accumulation. Jitter generation and accumulation in a chain of repeaters were studied in a previous paper using a 1B4B type line code 2• Jitter accumulation in a chain of 20 repeaters was tested with two types of line codes. The one is a 1B4B type code which is promising for extremely simple implementation. The other is a 3B4B/1B4B multipled block code which features in simple multiplexing. It is seen that Type A jitter (high frequency component of jitter 3) accumulates in proportion to number of repeaters in a chain N. It is shown that an extremely simple bandpass filtering with a Q as low as 5 can be used in each repeater for drastically reducing the accumulation of Type A jitter. Two types of line coding are tested in a chain of 20 repeaters to prove that the amount ofjitter accumulation can be substantially reduced.
