POI 10085 is a multi-band passive Point of Interface engineered for professional DAS and IBS wireless network deployments across 800, 900, 1800, 2100, and 2300 MHz bands. Designed for telecom operators, neutral-host providers, and system integrators, this rack-mount POI combines multiple cellular services into separated uplink and downlink paths for reliable in-building coverage. Its RF design uses duplexer and circulator paths, high-isolation band routing, 50 Ω impedance, low VSWR performance, and integrated power management through fixed and adjustable attenuation. The dedicated DL Test Port supports convenient monitoring and commissioning without disrupting live RF paths. Housed in a 19-inch 3U chassis with professional RF interfaces, POI 10085 is ideal for distributed antenna systems in airports, stadiums, commercial towers, transport hubs, and enterprise campuses. If you need a passive POI for multi-operator cellular coverage, this solution delivers stable performance, compact integration, and engineering-ready flexibility for long-term network growth.
