Connector Types

The most common fiber optic connectors for Powerwave repeaters are briefly described

below.

DIN

These are keyed, spring-loaded connectors with floating sleeves in the couplers. They

have threaded coupling nuts.

DIN/APC, see APC connectors below.

The ferrule in a FC connector has face contact (FC) with the joined connector. This type

has a threaded coupling nut.

FC/APC, see APC connectors below.

FC/PC, see PC connectors below.

The subscription channel (SC) connector is a push-pull connector that gives a click

sound when pushed in or pulled out. The ferrule in this connector is decoupled from the

cable and the connector body, which means that the ferrule is not affected by cable

touches.

SC/APC, see APC connectors below.

SC/PC, see PC connectors below.

The straight tip (ST) connector has a spring-loaded bayonet coupling that makes the

ferrule not rotate during connection, which means that the insertion loss is consistent.

APC connectors

All APC connector types are angle polished connectors (APC). In such a connector, the

ferrule with the fiber end face is not at straight angle to the fiber center axis (typical

deviation for the connectors used is 8° but a deviation of 5° to 15° is common). These

connectors have a low backreflection.

PC connectors

All PC connector types have the ferrule with the fiber end face polished in a certain

curve for physical contact (PC). These connectors have a low backreflection.

E2000 connectors

The E2000 connector has a ceramic ferrule and a moulded plastic body that includes a

push-pull latch mechanism. This connector has a spring loaded protective cap over the

ferrule that protects the fiber end face from dirt and dust and also protects from laser

emission.
