HINOC BRIDGE EM15
EM15

The EM15 series HINOC2.0 is a new generation of coaxial ultra-wideband access network equipment launched by KT to meet the requirements of the current access network with large bandwidth and low latency.

It has single in/out or double in/out RF interfaces, which is mixed output of IP data signal and CATV signal to CATV distribution network, and realize common cable transmission broadcast TV program and IP data. The equipment is installed on the optical node optical cable output line of HFC cable TV network or on the input line of the building user distribution network, to provide users with voice, video, data and many other services.

FEATURE

Wide frequency, large bandwidth.
 Single-end MAC layer rate reaches 700Mbps. Ultra-low delay and jitter characteristics.
 Using TDMA Multiple Access technology, 32-node transmission average time delay 2.5ms, the average jitter 5ms or less.
 OFDM+ adaptive modulation, maximum proximity to channel capacity.
 Support for uplink and downlink dynamic Bandwidth allocation (DBA)
 A full range of QoS assurance, telecom-level flow classification and scheduling.
 High reliability and good environmental adaptability
 The use of advanced waterproof, lightning protection measures, can be in the harsh environment all-weather stable and reliable work.
 PON+EOC Unified Network Management, support equipment automatic topology discovery, automatic distribution of business configuration, reduce operating costs.
