GPON

The GPON provided by Primus IT has three advantages: the first transmission
distance is longer, the use of optical fiber transmission, the coverage radius
of the access layer can reach 20 kilometres; the second can provide a higher
bandwidth, 2.5G downstream / 1.25 upstream per user G (physical layer); the
third optical splitting characteristic is strong, can lead to the multi-channel
to the home optical fiber from a single fiber at the office end after
splitting, saving optical fiber resources.

The Difference Between EPON and GPON Optical Fiber Networks

EPON and GPON china are two typical passive optical networks (Passive Optical
Networks, PONs), which belong to short-distance optical cables. They are often
used in urban areas to realize Internet surfing, Internet voice and digital TV
signal transmission. They can also be used in cellular base stations. Backhaul
connection, Wi-Fi hotspot communication, and even distributed antenna array.
The biggest difference between the two is that the download and uplink
communication protocols are different. 
GPON uses wavelength division multiplexing refereed as WDM technology to make
uploading and downloading at the same time. Usually, the download uses a 1490nm
optical carrier, while the upload selects a 1310nm optical carrier. If you need
to transmit TV signals, it will also use 1550nm optical carrier. EPON is fully
compatible with other Ethernet standards, so when connected to an Ethernet-
based network, no conversion or encapsulation is required, and the maximum
payload is 1518 bytes. 
EPON does not need to use the CSMA/CD access method in some Ethernet versions.
In addition, because Ethernet transmission is the main method of local area
network transmission, there is no need for network protocol conversion in the
process of upgrading to a metropolitan area network.

GPON Onu Device Functions

The network topology of passive optical fiber transmission is mainly composed
of OLT (Optical Line Terminal), ODN (Optical Distribution Network), and ONU
(Optical Network Unit). ODN provides optical transmission means for OLT and
ONU. It consists of passive optical splitter and passive optical combiner. It
is a passive device that connects OLT and ONU. The transmission of upstream
data is uniformly controlled by the OLT. The ONU transmits user data according
to the time slot allocated by the OLT to avoid data transmission conflicts
generated by the ONU. The ONU inserts uplink data in its own time slot
according to the time slot allocation frame, which realizes the sharing of
uplink channel bandwidth among multiple ONUs. Primus IT provides a variety of
customized solutions, including 5g, 10g gpon to sfp, from configuration
designing, programming and codingsolutions to fit our customer's gpon onu
device needs. 

Advantages of GPON System Technology

GPON is very popular in the optical fiber market. In addition to its advanced
technology, it also has the following advantages:
1. Range: Single-mode fiber can transmit data from 10 to 20 kilometers, while
conventional copper cables are usually limited to a range of 100 meters.
2. Speed: The downstream transmission rate of EPON is the same as its upstream
rate, which is 1.25 Gbit/s, while the downstream transmission rate of GPON is
2.48 Gbit/s.
3. Security: Due to the isolation of signals in the optical fiber, GPON is
essentially a safe system. Because they are transmitted in a closed circuit and
contain encryption, GPON cannot be hacked or eavesdropped.
4. Affordability: GPON optical fiber cables are cheaper than copper LAN cables,
and can also avoid investment in wiring and related electronic equipment,
thereby saving costs.
5. Energy saving: Contrary to the standard copper wire in most networks, the
energy efficiency of GPON has increased by 95%. In addition to efficiency,
Gigabit passive optical networks also provide a low-cost solution that can
increase users through splitters, which is very popular in densely populated
areas.
