Описание
Optical patch cords are used to switch optical communication lines and connect them to network and measuring equipment. An optical patch cord is a fiber optic cable terminated with an optical connector, if the cable is terminated with only one side, this kind of patch cord is called a pigtail. For our patch cords and pigtails we use only the best fiber produced by Corning, an important factor in the quality of the patch cord is also the quality of the connector and in our connectors we use only ferrules (Ferrule Connector) of the Japanese company Adamant.
The optical connecting cord is a patch cord terminated on different sides by different types of connectors. Pigtails can be single-mode and multi-mode.
Преимущества
- Two types of protection against overload and short circuit.
- Complete set of supplementary devices with the possibility of simple independent installation:
- – State contact KS47;
- – State contact KSV47;
- – Undervoltage trip RMM47;
- – Low-voltage release RN47.
- Indication of contact position.
- Latching on DIN-rail with double locking.
- Wide operating temperature range from –40 to +50° С.
- Updated wider engagement lever with improved contact area.
- Notches on contact terminals reduce heat loss and increase mechanical stability of the connection.
- Higher switching capacity of 10000A provides for installing VA47-100 as input circuit breakers.
