Brief introduction
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.)
