What Are Fiber Optic Connectors?
Fiber optic connectors are pluggable components used to join optical fibers or connect fibers to equipment. Choosing the right fiber optic connector is critical for network performance.
LC Connector (Lucent Connector)
LC uses a 1.25mm ceramic ferrule, half the size of SC. Features push-pull latch mechanism. Low insertion loss (≤0.15dB typical). Ideal for high-density applications. Most SFP optical modules use the LC interface.
SC Connector (Subscriber Connector)
SC uses a 2.5mm ceramic ferrule with push-pull coupling. Most widely deployed connector globally. Low cost, reliable, suitable for frequent plugging. Main application: FTTH and PON networks.
ST Connector (Straight Tip)
ST uses a 2.5mm ferrule with bayonet locking mechanism. Rugged and durable, lock stays secure. Suitable for industrial environments and multimode networks.
FC Connector (Ferrule Connector)
FC uses 2.5mm ferrule with threaded screw-on mechanism. Excellent vibration resistance. Ideal for test equipment and high-precision measurement. Used with optical power meters.
MPO/MTP Connector (Multi-fiber Push-On)
MPO connects multiple fibers (12, 24, or 72) in a single interface. Ultra-high density. Designed for parallel optics (40G/100G/400G).
Ferrule End Face Types
PC (Physical Contact): ~-40dB return loss
UPC (Ultra Physical Contact): ~-50dB return loss
APC (Angled Physical Contact): ~-60dB return loss, for reflection-sensitive applications
Our product range includes fiber adapters, fiber attenuators, and fiber cleaning tools for comprehensive connector maintenance.
Conclusion
Choose LC for data centers, SC for FTTH, ST/FC for industrial environments, and MPO for high-density parallel optics. Visit Langzhi Technology for all your fiber optic connector needs.
