USD Call for Quote


GAOTek 16 Channel Unidirectional/ 8 Channel Switch Bidirectional Optical Multiplexer is designed to expand and grow a network which is used in optical fiber transmission to overcome the electromagnetic interference and lightning damages.It provides the scope to expand and grow a network where higher speeds and feeds are required, without impacting or disrupting the original communications along with providing an easy, seamless means of adding services.  Also it improves the reliability of communication, data security and confidentiality of the network. It can be widely used in various industrial control, process control and traffic control offices especially in banks, electrical places and work stations with electromagnetic interference in the environment.


  • The switch operates on integrated circuit technology.
  • When the switch is turned on, or when connected to other switches or when the fiber state is stable, it does not show any chaotic action status.
  • It can support one-way, two-way, eight-way or 4-way switches.
  • The switch supports interface Lightning standard IEC61000-4-5 (8 / 20 μS).
  • It also supports differential mode: 6 KV, impedance (2 Ω); Common mode: 6 KV, impedance (2 Ω) standards.
  • Power supply is optional AC 220 V, DC -48 V, DC + 24 V, DC power.
