Details

GTW-EC8122H-RN is an all-in-one EOC Master with EOC master module, ONU module and OR module. It can instead of three type products, HFC optical node, EPON ONU and EOC mater. It can reduce the number of active node in the system, decreasing failure rate and saving a space. It is the best choice of CATV, Internetand VOD for the operator.

 

The EOC Master Module in the GTW-EC8122H-RN is based the Qualcomm INT7410 chipset solutionwith high anti jamming capability OFDM technology. The 7.5-65MHz low frequency band is used for EOC signals. Built in high isolation filter as CATV RF and EOC signal mixer, the EOC signal and CATV signal in 87~862MHz can run on one cable without interference. The EOC Master can provide high speed data service. The PHY Layer speed is 700Mbps, the MAC Layer throughput is up to 320Mpbs. Each EOC Master module can support up to 253 EOC slavers.

 

The OR(Optical Receiver) module in the GTW-EC8122H-RN can provide an HFC optical input and one RF output. The CATV signal will convert from optical to RF signal here. The OR module is a high quality optical receiver product. It received the optical signal from the TX of HFC network, and the signal processed by the PIN, Amplifier, EQ and AGC to a stable RF output. The output level will be up to 108dBuv.

 

The ONU module in the GTW-EC8122H-RN designed with one GEPON port, two standard 10/100/1000 Base-TX Ethernet ports. It provides the key functionality of 802.3ah EPON ONU. By using the GEPON technology, the ONU module provides a high-speed data channel through a single optical fiber with a rate of 1.25 Gbit/s on bi-direction. In addition, it offers the QOS, flexible bandwidth allocated to provide quality high-speed data service, voice service, and video service.
