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.
