Handling Fiber Optic Cable & Connectors

This product is supplied with angle‐polished connectors (APC) and these must not be confused

with standard flat, spherical or "super" polished connectors. These connector types are not

interchangeable and mating one with the other will damage both the cable and the equipment.

The specification of the optical connector is critical to the performance of the complete fiber

optic link.

Note that a yellow jumper indicates single mode fiber, but the connector end must be green

indicating an angle cut connector (APC).

Ensure that all mating connectors are matched types. All Optical Zonu equipment uses APC

connectors.

Figure 10. Optical Zonu products use APC (angle polished connectors). These are

always single mode and are indicated by a green boot. Do not try to connect UPC

(ultra-polish connectors – indicated by a blue boot). These are flat polished

connectors that will damage the mating APC connector.
