Optical Fibre Solutions - Universal Base Station to DAS Fiber Transport
Rojone has partnered with Optical Zonu to offer its customers ZONUConnect. ZONUConnect is a simple yet universal fibre optic transport system between any multi-sector base station and any DAS (Distributed Antenna System) for distances from 300 ft to 16 miles. It solves the remote connectivity problem with a fully-integrated menu of choices for Point-of-Interface to connect with any base station configuration and DAS Interface to connect to any DAS. It also offers a data-link for easy, web-based set-up and SNMP remote monitoring and control.
Passive intermodulation (PIM) is a form of intermodulation distortion that occurs in passive components such as antennas, cables, connectors, or duplexers with two or more high-power input signals. PIM in the transmission path degrades the quality of the wireless communication system.
PIM is caused by non-linearities in a passive circuit. Major causes of non-linear action in a connector or cable assembly are poor contact junctions, which can be caused by any one or more of the following:
- Insufficient contact pressure
- Irregular contact surfaces
- Oxidation-causes metal/oxide junction
- Poor workmanship
- Contact impurities
