Allow Partial Shipments
The UHF SMART Coupler SC-xxN-450 combines a specially developed narrow band, 380-512 MHz, passive coupler with active diagnostic technology for system monitoring with failure detection and malfunction location capabilities.
The SMART(System Monitor Alarm Report Technology) Passives system comprises a SMART Gateway at the headend and SMART Coupler deployed in the DAS. Each coupler reports the VSWR at each port based on a calibrated CW tone generated by the gateway. The SMART Coupler can report failures such as open/short circuits when the network may not be operating as intended by storing and comparing the VSWR at the port over time. The SMART gateway then communicates the alarm via e-mail, SMS, or SNMP. It also pinpoints the location where the failure occurred.
The real-time monitoring that the SMART Passives system provides ensures that public safety DAS integrators, Authorities Having Jurisdiction (AHJ), and building owners can rely upon the operation of their critical communication systems.
