I was planning to replace the white Jio cable with directly yellow one i came to know it is more better since it is flexible but expensive then white one that is why jio dont use whole cable as yellow one! But as i looked into i came to know this yellow cable are called SC to SC patch Cord and are in single mode(since yellow colored) but again now question is in single mode also there are 2 types one is Simplex mode other is Duplex mode(it is not multi mode since they are orange color). So which one should i order if want to replace white wire on my own which one should i go with single mode with simplex or duplex? Any help is appreciated!
