EOC Master(ONU+EOC+OR)OPE7921
Product Overview
OPE7921 is an all-in-one EOC Master with EOC master module, MC module and OR module.
We can one OPE7921 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, Internet and VOD for the operator.
The EOC Master Module in the OPE7921is based the Qualcomm AR7410 chipset solution，with 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 600Mbps, the MAC Layer throughput is up to 320Mpbs.
The OR module in the OPE7921 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.
OPE7921built in a media convert, 10/100/1000Mbps media converter. The module supports IEEE 802.3, 802.3ab, 802.3u, 802.3z standards. It provide one SC/PC optical connector for 1000Base-Lx and one 10/100/1000M auto-negotiable Ethernet RJ45 interface.
