The connector terminal surface of optic fibre is exposed to way PC, UPC, APC
1,The connector terminal surface of optic fibre has PC, UPC, APC type three kinds to contact the way.
2,PC - -It is a physical terminal surface to insert the body terminal surface of needle; UPC - -It is a super physical terminal surface to insert the body terminal surface of needle; APC type - -It is the physical terminal surface of angle to insert the body terminal surface of needle;
3,Except that physics is different, Wire harness there are return waves echoes that loss, reflect and loss differently in the difference between three. Damages are that the difference goes back: PC¡Ý 40dB, UPC¡Ý 50dB, APC¡Ý 60dB.
Three kinds of common optic fibres connectors:
FC/PC: FC, the end to end fine connector of round, PC, the ceramic section is a level;
SC/PC: SC, the end to end fine connector of the side, PC is the same;
FC/APC: FC, the same, APC, regards sectional centre as the centre of a circle, slopes 80 degrees outwards.
FC/PC FC/UPC FC/APC can mix terminals, connect, it is can very heavy for signal not to decay, insert, decrease, should smaller than 0.5dB according to national standard
