FTTH Types
GPON
GPON (Gigabit-Capable Passive Optical Networks) technology is the latest generation of broadband passive optical integrated access standard based on the ITU-TG.984.x standard. It has many advantages such as high bandwidth, high efficiency, large coverage, and rich user interfaces. Considered by most operators as an ideal technology to realize broadband and comprehensive transformation of access network services.
10G ASYMMETRIC EPON
The asymmetric system only has a downlink rate of 10.3125 Gbit/s, while the uplink rate is still 1.25 Gbit/s. As the first mature next-generation PON technology, 10G EPON technology is in line with network development trends. It has the advantages of large bandwidth, large optical splitting ratio, compatible networking with EPON, unified network management, and smooth upgrade.
GEPON
GEPON generally refers to a passive optical network as a pure medium network, which avoids electromagnetic interference and lightning effects from external equipment, reduces the failure rate of lines and external equipment, improves system reliability, and saves Maintenance cost is a long-term technology that the telecom maintenance department expects.
Ftth 10GSYMMETRIC EPON
Symmetrical mode: That is, the uplink and downlink rates are both 10G. The asymmetric mode can be considered as a transitional form of the symmetric mode. In the early stage where the upstream bandwidth demand is less and the cost is more sensitive, the asymmetric mode can be used. With the development of business and technological progress, it will gradually transition to an asymmetrical model.
XGSPON & GPON COMBO
Combo, as the name implies, means a combination. Combo PON is a combination of GPON and 10G GPON. It uses two technologies to adopt different bearer wavelengths. The two wavelengths are combined in one optical module to achieve independent transmission of GPON and 10G GPON optical signals.
FTTH Fiber to the HomeChina
FTTH (Fiber to the home) is a transmission method of fiber communication. Specifically, FTTH refers to the installation of optical network units (ONU) at home users or corporate users and is the type of optical access network application that is closest to users in the optical access series except for FTTD. The notable technical feature of FTTH is that it not only provides greater bandwidth, but also enhances the transparency of the network to data formats, rates, wavelengths, and protocols, relaxes the requirements for environmental conditions and power supply, and simplifies maintenance and installation.
Advantages of FTTH technology
Applications of FTTH service
FTTH 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, especiallyEPON, is widely used in the access network. EPON and GPON manufacturer put efforts onpromoting the simplification of the network level, makes the network structure clear, management and maintenance more convenient, and greatly reduces 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 this 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) fiber to the roadside, 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 kilometer" bottleneck from the Internet backbone to the user's desktop. With the upgrading of technology, the cost of fiber to the home is greatly reduced, which will soon be comparable to DSL and HFC, which makes it possible to make FTTH practical. In addition, FTTH technology is also used to solve the "last kilometer" problem in the information superhighway. FTTH+ Ethernet is much faster than ADSL and ISDN.
Primus IT is a professional optical transceiver supplier, we provide ftth in networking, home passed ftth, new fiber to the home, ftth to ethernet converter,ethernetand etc. Primushas been dedicated to developing, manufacturing and marketing for optical transceivers.
