What are the line sequence types of MPO fiber jumper?

In the order details, Mothod A and Type A, Mothod B and Type B, and Mothod C and Type C are the same meaning. In Chinese, Type A is a parallel practice, Type B is a crossover process, and Type C is a line pair crossover. . However, many unprofessional fiber patch cord manufacturers or manufacturers who only produce single and double core patch cords and do not produce MPO fiber patch cords often do not confuse the parallel practice of the MPO line sequence with the crossover method because they do not understand enough to avoid confusion. It is still based on drawings and reduces unnecessary losses.

In the 40G QSFP module, the Type B format is generally used, but in the final form, it has to be clearly identified with the customer.
