1.2.3
Flexible networking method
Triple-play solution
◼
The FTTx system adopts wavelength division multiplexing technology. By adding a combiner to the
external of the TES70 series devices, CATV signal and user's data service and voice service are
transmitted in the same optical fiber, realizing the three service integration in one network.
Point-to-multipoint optical access solution
◼
The TES70 series devices are connected to the terminals in users' home through optical fiber,
providing users with high-speed data Internet access and multicast IPTV services.
1.2.4
Powerful GPON access capability
As a multi-service access platform, TES7004/7008/7016 can provide multiple access modes and
support multiple networking modes to meet the networking requirements of users in different
environments and services.
Support GPON function specified by ITU-T G.988/ITU-T G.984 standard.
−
Provide data and video services by using a single optical fiber to meet the individual
−
needs of users.
Provide large-capacity GPON transmission bandwidth. Uplink rate ≥ 1 Gbit/s; Downlink
−
rate ≥ 2.2 Gbit/s
GPON system adopts passive optical transmission technology, and the optical path
−
separation adopts the way of Point to Multiple Point (P2MP).
It has a split ratio of 1:128, thereby increasing capacity, saving fiber resources, and
−
facilitating network expansion.
Support Dynamic Bandwidth Allocation (DBA) algorithm: The minimum bandwidth
−
allocation granularity of DBA is not greater than 512 Kbit/s. The configurable minimum
bandwidth of DBA is not greater than 256 Kbit/s. The accuracy of DBA is greater than
+5 %.
Support up to 20 km long-distance transmission.
−
Support multiple types of ONTs.
−
1.2.5
Complete multicast function
TES70 series devices are equipped with the structural characteristics of PON network
Point-to-Multi-Point (PTMP), which is the best access structure for multicast services. With the
multicast function, it is convenient to provide users with some new value-added services, including
live broadcast, internet radio, IPTV, telemedicine, distance education, real-time video conferencing
and other internet information services. TES70 series devices support the following multicast
functions.
