RS-232/485/422 to Fiber Optic Converter

Interact with this product in a Layout Tool:

The 2406DT13-F2 is a rugged, industrial grade data transceiver which provides an economical method of transmitting one bi-directional serial RS-232, RS-422, or RS-485 data over a pair of single mode fibers. Used as a pair, the maximum end to end single mode fiber distance is 40km.

The 2406DT13-F2 supports data rates up to 115.2kbps and is capable of autosensing the applied data format.

*Note: Supports one data type at any given time
