Description
Overview
The GAOTek 4 Unidirectional/2 Bidirectional Channel Optical Multiplexer is a 1-4 switch output optical transceiver which is used in optical fiber transmission to combat electromagnetic interference and lightning damage. This optical multiplexer is based on proprietary integrated circuits and provides a one-way road switch or 2 two-way switch in optical fiber transmission to improve the reliability of communication, data security, and confidentiality. It is widely used in industrial, process, and traffic control- especially in banks to prevent electrical and electromagnetic interference from the environment as per the special requirements of the department and the system.
Features
- Based on proprietary integrated circuit
- Can be configured as an input (a) / 2 inputs (a) / 4 inputs (out) / 1 input + output / 2 inputs + output mode
- Enter the normally open normally closed switch and it automatically detects when to input and what state to switch the output. This facilitates the opened project.
- When the switch is turned on and not connected to other switches or the fiber state is stable and does not appear as a chaotic action status
- It can support one-way, two-way and four-way switch
- Each switch has an On and Off light
- The switch interface is lightning reach: IEC61000-4-5 (8 /20 μS) differential mode: 6 KV, impedance (2 Ω) Common mode: 6KV, impedance (2Ω) standard
- It has an optional AC 220 V, DC -48 V, DC + 24V , DC power with no positive and negative points
