1. Brief introduction
According to the analysis of Triple Play service demands for the network transmission,
and under the current trend of “Copper Retreat Into Light”, “FTTB” , “IP signal
transmission”, network optical fiber/optical cable structure adopt the dendritic mode
becomes necessary.
“FTTB”+EoC technology can save the broadcast transmission source as well as the
investment of IPQAM and CMTS equipments. Now EoC single module can reach to
100Mbps and can differentiated service by Vlan. This system gains an excellent indicator
and business support capacity, almost gains no difference with FTTH. (FTTH need to
solve the last 10 meters transmission to user’s desk)
Select the most suitable EoC equipments according operator’s real situation is the
key point. KT EoC products adopt the modular design; can increase the EoC headend
master to meet the increased subscriber’s demands, and can expansion the system by
increased the master in the future. Replace modules will not affect the TV signal.
KT EoC products all keeps the same product form even with different EoC solution,
so can constitute the EoC headend products by install related EoC master module.
After many years real network operation, KT can provide various types of EoC
products to suitable for different environment.

Feature and Advantages
Adopt HomePIug AV,IEEE P1901 standard, use HFC frequency below 65MHz to
develop data access
High anti-interference capacity and low reliability to network transmission capacity
The transmission rate capacity of each main module is higher than that of CMTS, but
the cost of every MHz bandwidth is 100 times lower
Use present HFC coaxial indoor TV network, no need to build new network and make
the second indoor cabling project
User CNU need not configuration, PnP
Broad application dynamic range which can suit for various quality networks to
develop business very quickly
Mature headend and CNU equipment technique, low cost
Fast and easy construction, little line maintenance
Perfect VLAN/VLAN priority number and remote upgrade function
Module design
System application
The main business of CATV network is still video program transmission. Meanwhile
the current HFC network provides video program, optical fiber link adopts optical fiber
transceiver, ONU or other optical switch, coaxial cable link adopts EoC advice to realize
data signal transmission, in order to realize to PC via HFC as well as develop data
business by low coast.
