    Dear experts.

     

    Is there somebody able confirm my finding  that 12 fiber MTP/MTP single mode patchcord polarity B (crossover,rollout) is the right polarity type to connect QFX switches back-to-back 100GE using JNP-QSFP-100G-PSM4 transceivers please?

     

    It is bit asking for kind nod because RX/TX need to swap on both ends.

     

    Thank you

    Hi all.

     

    I confirmed via e-shop of one fiber optic vendor (parametric filter search) the 12 fiber MTP/MTP single mode patchcord polarity B (crossover,rollout)  is indeed the correct polarity patchcord for connecting QFX switches back-to-back 100GE using JNP-QSFP-100G-PSM4 transceivers.

     

    Nice day to all of you.
