Pdh microwave transmission equipment is a high-performance, low-cost, secure and reliable transmission products.
Pdh microwave transmission equipment includes indoor unit (idu), outdoor unit (ODU, the RF unit), antenna and all basic accessories.
Pdh microwave transmission equipment supply point-to-point radio connection in the telecommunications network, which is widely used in enterprise access, interconnect base stations, emergency communications, community access and relay connecting link.
Pdh microwave transmission equipment(idu) is designed for different RF unit working in different RF frequency band, 5.8/7/8/13/15/18/23 GHz. And the idu used the same if interface to connect to all these odus through coaxial cable.
