Applications Of FTTH Service
FTTH telecom is a comprehensive access solution for all services. Although the main driving force of FTTH is broadband video services in the future, FTTH must be able to support a variety of existing narrowband and broadband services, as well as possible new services in the future. FTTH system must be able to provide integrated access so that users can enjoy multiple services at the same time.
PON technology, especially EPON, is widely used in the access network. EPON and GPON manufacturers put efforts on promoting the simplification of the network level, making the network structure clear, management and maintenance more convenient, and greatly reducing the cost of computer room, electricity, and maintenance. The current access network construction is widely implemented by EPON, and common networking methods include FTTB+LAN, FTTB+EOC, and even FTTH.
In the past, EPON devices were mostly independent box-type devices with low port density, low capacity, and simple business functions. Now, operators mostly adopt integrated equipment that combines EPON and Layer 3 switches, especially the integration of large-capacity, multi-function switches. EPON is inserted into the chassis of the switch as a plug-in card (multiple EPON modules can be inserted), so that the OLT part of EPON and the aggregation layer switch are integrated, which further simplifies the network structure.
Another advantage of FTTH telecom is to make business processing more flexible and convenient, such as flexible QinQ technology, VLAN three-layer termination, and even MPLS VPN services. At present, the integrated equipment with the highest business performance can provide 160 PON ports, which fully meets the operators’ high-bandwidth and large-capacity access requirements.
FTTH Telecom Development
In the optical access family, there are FTTB (Fibre To The Building) fiber to the building, FTTC (Fibre To The Curb), FTTSA (Fibre To The Service Area) fiber to the service area, and so on.
When the optical fiber is directly connected to the user's home, there are no restrictions on its bandwidth, wavelength and transmission technology. it is suitable for the introduction of various new services. it is the most ideal service transparent network and the ultimate way for the development of access network. Although the development speed of mobile telecommunication network is amazing, because of its limited bandwidth, the terminal volume can not be too large, the display screen is limited and other factors, people still pursue the fixed terminal with relatively superior performance, that is, they want to achieve fiber to the home.
The charm of fiber to the home lies in its great bandwidth, which is the best way to solve the "last mile/last kilometer" bottleneck from the Internet backbone to the user's desktop. With the upgrading of technology, the cost of FTTH is greatly reduced, which will soon be comparable to DSL and HFC, which makes it possible to make FTTH practical. FTTH+ Ethernet is much faster than ADSL and ISDN.
Advantages of FTTH Technology
1. Very large transmission speed and high bandwidth.
2. Its bandwidth is relatively wide, and the long distance is exactly in line with the large-scale usage.
3. Easy and fast installation.
5. Low-cost maintenance, low losses in network.
6. Enhance the transparency of the network to the data format, rate, wavelength and protocol.
7. Relaxed requirements on environmental conditions and power supply.
8. Increased reliability of broadband transmissions in comparison to other networks.
