4 Channel Dry Contact Closure over Optical Fiber Modem Mini type

Description

A dry contact closure is a simple on/off mechanism, often used for signaling or control purposes. The dry contact closure over fiber converter transmit four channel dry contact closures (typically open/closed state signals) over fiber optic cables. The dry contact closure over fiber converter have advantages such as immunity to electromagnetic interference, higher bandwidth, and longer transmission distances up to 120km.
The fiber converter are made of one pair device. one is transmitter which convert dry contact closure signals into optical signals. Another is receiver which receive the optical signals and convert them into electrical signals. The dry contact closure information is extracted.
