  • Optical cables are passive devices

    Optical cables are passive devices

    Fiber optic passive components are devices used in fiber optic communication systems that do not require an external power source to operate. These components serve various functions such as routing, coupling, splitting, and managing optical signals within the network. This is particularly important in laser systems, where back reflections can destabilize the light source or damage sensitive. A passive optical network (PON) or Gigabit Passive Optical Network (GPON) is a point-to-multipoint (P2MP) network that uses a combination of active transmission equipments and passive cable components to provide network connectivity to end user's devices.

  • Relay protection devices generally consist of components

    Relay protection devices generally consist of components

    Electromechanical protective relays operate by either, or. Unlike switching type electromechanical with fixed and usually ill-defined operating voltage thresholds and operating times, protective relays have well-established, selectable, and adjustable time and current (or other operating parameter) operating characteristics. Protection relays may use arrays of, shaded-pole, magnets, operating and restraint coils, solenoid-type operators, telephone-relay contacts.


  • Pre-shipment acceptance testing of relay protection devices

    Pre-shipment acceptance testing of relay protection devices

    A comprehensive testing program should simulate fault and normal operating conditions of the relay. Acceptance testing, commissioning, and startup will include control power tests, current transformer and potential transformer tests, and any other device testing . The testing and verification of relay protection devices can be divided into four groups: Type tests are needed to prove that a protection relay meets the claimed specification and follows all relevant standards. Since the basic function of a protection relay is to correctly function under abnormal. Installation tests are field tests to determine that the protection operates correctly in actual service.

  • NIPS network security devices

    NIPS network security devices

    A Network Intrusion Prevention System (NIPS) is a proactive security appliance or software solution that monitors network traffic for malicious activity and automatically takes action to block or prevent those threats in real-time. IPS typically logs data pertaining to observed events, notifies. Along this rocky road, Network Intrusion Detection and Prevention Systems (NIDS / NIPS) became an enterprise best practice–now widely considered essential at the network edge as well as at key junctions leading to high-value, [. ] Enterprise Networking Planet content and product recommendations are. A network-based intrusion prevention system (NIPS) is a type of security solution that is designed to protect networks by monitoring and analyzing network traffic in real-time for signs of malicious activity. When sketchy traffic shows up (and it always does), the system shuts it down in milliseconds. Think of NIPS as that security guard who never needs.
