Dab tsi txuas hom txuas koj yuav tsum qhia kom meej rau ftth tso cable thaj cords?
SC/APC (angled physical contact) connectors dominate modern FTTH deployments due to superior return loss performance (>60 dB), reducing reflections critical for CATV services. LC/APC connectors offer higher density in space-constrained applications but at slightly higher cost. Avoid SC/UPC or LC/UPC (non-angled) connectors in FTTH networks where CATV overlay might be required-the return loss difference (35-45 dB for UPC versus >60 dB rau APC) ua rau pom cov yeeb yam tsis zoo video.
