China WD-C1000M-MD SD Coaxial Ethernet Adapter for Home Office.

This low frequency coaxial line network bridge which can transfer bidirectional data through coaxial cable was developed based on the Coaxial cable broadband access technology, one of the high-speed Quasi gigabit network products which were developed under the latest G.hn international standard issued by ITU-T. Transfer the Ethernet signals through coaxial cable of cable TV, could upgrade the original coaxial cable network into a carrier-class broadband access network which can be operated and managed.
Coaxial cable bridge modulates the standard Ethernet signals output from ONU into the RF signals which could be transferred in coaxial cable, and the adoption of OFDM technology makes it can transfer the data stably in a complicated networking environment.
Local side product provides a join-in bandwidth at the rate of 900Mbps, using 7.5-100MHz low-frequency channel, effectively avoid the conflict between the existing CATV system frequency occupation and the product, reduce the interruption of each other. Support CATA network of tree and star structure, it has the features of long distance transmission, good network adaption and high bandwidth etc..
The product has the function of reverse power supply which can solve the problem of outdoor access device power supply.( Indoor Slave supply power to Master as well as Master supply power to other devices with DC12V.)
