1 Introduction
1.1 Product Description
The EOC system is a "last 100 meters" solution for network operators to provide
broadband access. Coaxial cable is used as the physical layer transmission medium to
provide symmetrical Ethernet transmission channels.
EOC series products have many advantages such as flexible deployment, high bandwidth,
high security, good reliability, convenient management, and simple maintenance.
EOC technology theory: EOC system uses coaxial lines to transmit data signals at below
65 MHz. When transmitting, the user data is modulated using GMSK or OFDM modulation
technology, and then transmitted on the coaxial cable. At the receiving end, the modem
can demodulate the signal to obtain the original communication signal.
1.2 Networking Introduction
The EPON ONU network signal is transmitted to the CD7944N EOC master. The coaxial
cable is used as the physical layer transmission medium to send the signal to each user's
home. Users only need to connect the EOC slave on the coaxial cable at home to use.
The networking diagram is shown below:
