How are the Zhongbo optical switches
The OPB610 and OPB620 sloted optical switches consist of an infrared emiting diode and an NPN silicon phototransistor with an enhanced low current roll-of to improve contrast ratio and immunity to background irradiance. Optical switching represents a fundamental technological evolution, shifting data routing from the domain of electrons to the realm of photons, or light. This is achieved using a patent pending opto-mechanical configuration and activated via an electrical control. Optical switches, which control the path of light signals without converting them to electrical signals, offer significant advantages in terms of speed, bandwidth, and efficiency.

Can access switches be configured with network management
Unmanaged switches are designed to just plug in and run, with no settings to configure. Those attributes make them more. Network switches are the key components in the production network for secure communication and real-time data sharing between RTUs, PLC frontend servers, workstations, and HMIs. A managed switch offers greater control and flexibility compared to an unmanaged switch, allowing for advanced configurations and optimizations to meet specific networking requirements. These access policies are typically applied to ports on access-layer switches to prevent unauthorized devices. Management VLAN provides a safer method to manage the switch. With management VLAN configured, only the hosts in the management VLAN can access switches' GUI.
