Description
Why Choose the FC/APC-FC/APC-SM-SX Model?
This specific cable is engineered to solve two major networking headaches: vibration-induced signal loss and back-reflection. The threaded metallic housing of the FC connector provides a secure mechanical lock, while the 8-degree angled polish of the APC ferrule pushes reflected light into the cladding, maintaining a return loss of over 60dB.

Expert Q&A for Network Engineers
Q1: Why is the FC connector still popular despite the rise of LC/SC?
The threaded, metallic design of the FC connector is virtually immune to accidental pull-outs or vibration. It remains the “gold standard” for test equipment, laboratory settings, and industrial environments where physical stability is paramount.
Q2: What happens if I connect this to a Blue (UPC) FC adapter?
Connecting an APC (Green) to a UPC (Blue) will result in a massive air gap. This causes high insertion loss and can physically scratch the fiber end-faces. Always ensure your adapters and connectors match by color.
Q3: Is this cable suitable for 40G/100G networks?
Yes. While the connector is “Simplex,” the Single-mode fiber core (OS2) easily supports high-bandwidth protocols over long distances, provided your transceivers are configured for single-strand operation.
