GEPON

The non-light source network is a point-to-multipoint optical fiber
transmission and access technology. The downlink adopts broadcast mode and the
uplink adopts time division multiple access. It can flexibly form trees, stars,
bus and other topological structures. Only need to install a simple optical
splitter, so it has the advantages of saving optical cable resources, sharing
bandwidth resources, saving machine room investment, fast network construction,
and low comprehensive network construction costs.

GEPON Technology Principle
GEPON technology adopts a point to multipoint user network topology and uses
optical fiber to realize the purpose of full service access of data, voice and
video. However, compared with the previous APON / BPON based on ATM technology,
GEPON realizes the transmission of Ethernet frames in user access network,
which is very suitable for the transmission of IP services. In addition, due to
the current universal construction of IP network, the components based on
Ethernet technology have relatively simple structure, high performance and low
price, which makes GEPON easier to be commercialized on a large scale compared
with other PON technologies; With the rapid development of various services
based on IP and the trend of IP convergence of the next generation network,
GEPON can be applied to a wider range, and conforms to the development trend of
the future network. It has become the most important FTTH technology.

GEPON Network Applications
GEPON technology transmits data in the form of IP packets without protocol
conversion. It can provide various WAN interfaces and connect with IP network
devices. It can provide Gigabit Ethernet interface and provide switching and
routing functions of IP network layer 2 and layer 3. It can provide users with
data, video and telephone network interfaces. Therefore, it can support VOIP
voice service, network TV service, VOD on demand service, video conference,
teleconference, videophone and other services. Its characteristics and
advantages will provide new opportunities for the development of various new
services.

GPON vs. GEPON 
The meaning of GEPON is Ethernet Passive Optical Network, which is a new type
of optical access network technology. GEPON is produced under the promotion of
some equipment manufacturers. It aims to combine the simplest and most widely
used Ethernet technology with GPON system to solve the problem of Ethernet
access in a point-to-multipoint manner. GEPON technology is relatively simple,
high speed and strong scalability. It can transmit signals with strong real-
time requirements by sending packet signals, so as to well support TDM
services. Through the transformation of GEPON system, packet signals are sent
regularly in a similar TDM mode to transmit signals with strong real-time
requirements, so as to well support TDM services.
GPON is an operator driven solution. At the initial stage of GPON standard
formulation, collect the business requirements of operators in FSAN to form a
GSR (GPON business requirements) document, which is numbered g. GPON. GSR as
one of the standards submitted to ITU-T. GSR document is the basis for the
formation of GPON standard. In order to define a service with higher
transmission rate and efficient support for a variety of services, including
circuit services, according to the service requirements of operators described
in GSR.
The advantages of GEPON are mainly reflected in low cost and high performance.
GEPON has obvious advantages in networking cost. Only one optical fiber is
required between OLT and ODN. Node equipment is not required at the optical
branch point. Only a simple optical brancher needs to be installed, which saves
a lot of optical cable resources. The signal does not pass through the active
equipment in the transmission process, so that the system has high reliability,
easy maintenance and low maintenance cost. The system adopts optical passive
branching technology. A single fault does not affect the operation of the whole
system, with strong anti-interference ability and more stable operation. GEPON
adopts tree network structure, supports multi-level connection of beam
splitter, reasonable collocation of cascade beam splitter and more flexible and
easy to use networking mode.
At present, GEPON technology has been tested and applied at home and abroad.
The GPON technology is still not very mature. At present, the publicity at home
and abroad is relatively mature. Many manufacturers at home and abroad have
launched GEPON solutions, and few manufacturers (about three) say they can
provide GPON solutions. Although GPON technology is the optical fiber access
technology expected by operators to efficiently integrate various services, the
price problem is still the key for operators to be confused about this
technology.
