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 Network
EPON and GPON 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.
For generally applications,GEPON routerwith 1 PON and 1 Gigabit port.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 gpon optical network technology 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, including5g, 10g gpon to sfp, from configuration designing, programming and codingsolutions to fit our customer's gpon onu device needs. In addition,Combo PON makes it easy to upgrade to 10G PON services by supporting the GPON user base.
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:
Primus IT is a professional optical transceiver supplierand gpon manufacturers, we provide ftth in networking, sonetand etc. Primushas been dedicated to developing, manufacturing and marketing for optical transceivers.
