KINZ ST fiber optic connectors are designed specifically for plastic optical fiber (POF) systems, providing a highly reliable metal-based adapter solution. They support a variety of fiber core sizes from 250μm to 1500μm and are suitable for applications in industrial sensing, automotive electronics, and medical equipment. Their nickel-plated stainless steel housing and precision ceramic ferrule ensure excellent mechanical strength and signal transmission stability.

1. Structural Characteristics
Aperture diameter: can be customized, mostly made of ceramic or metal, compatible with multimode fiber (50/62.5μm), single-mode is less used.
Locking method: snap-on rotation lock (rotate 90° to fix after insertion), similar to BNC connector, with better vibration resistance than plug-in interface.
Shell material: metal or high-strength plastic, suitable for industrial environment.
2. Performance Parameters
| Parameter | Specification | Notes |
| Insertion loss | <0.5dB (typical 0.3dB) | Equivalent to FC/SC |
| Return loss | ≥25dB (PC end face) | Mostly used in ordinary data transmission scenarios |
| Tensile strength | ≥90N | Industrial-grade reliability |
| Working temperature | -40℃~70℃ | Adapt to extreme environments |
| Plug-in times | >1000 times | Long-term use stability |
3. Application Scenarios
Network type:
10Base-F Ethernet (early standard), enterprise LAN (short-distance multimode transmission), military communication equipment.
Typical scenarios:
Fiber distribution frame: used as a transfer node for trunk and branch optical fibers.
Military/medical equipment: relies on its anti-vibration characteristics (the bayonet lock is not easy to loosen).
Industrial control: suitable for workshop-level data transmission of multimode optical fiber.
