10G ASYMMETRIC EPON

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. 10GEPON and EPON are in the same line. Use the existing network to directly increase the speed by 10 times, and perfectly match the bandwidth planning of the telecom operator, support the realization of the telecom operator's mid-and long-term planning goals, and support the continuous expansion of the operator in IDC business, government and enterprise customer business, and family customers.

What is 10g EPON(GEPON) ONU?

EPON refers to an optical fiber access system. The ONU is the terminal device of the system, which can be used to connect to computers of home users and devices of industrial users. Two functions of our 10g EPON ONU: selectively receive the broadcast sent by OLT; collect and cache the Ethernet data that needs to be sent, and send the cached data to the OLT terminal according to the allocated sending window; effectively improve the uplink bandwidth utilization rate of the whole system, and configure the channel bandwidth according to the network application environment and the characteristics of applicable services; can carry as many end users as possible without affecting the communication efficiency and quality, improving the network utilization rate and reducing the user cost.   

What is 10g EPON(GEPON) OLT ?

EPON (Ethernet Passive Optical Network), has the characteristic of saving optical resources and is transparent to network protocols. EPON uses a single optical fiber to connect the OLT, and then the OLT connects the ONU. The 10g EPON OLT device is an important local device. It can be connected to the switch at the front end by using internet fibre 10g epon cables and connected to the optical splitter at the client end by using a single optical fiber. Fibre techno 10g epon can realize the control and management of the client device. Like the ONU equipment, it is also a photoelectric integrated equipment.


EPON vs. GPON vs. 10G-EPON

EPON is a kind of PON network. The EPON network consists of OLT, ODN, and ONU.  The main features are point-to-multipoint, passive line, simple and clear network layer, providing comprehensive access to voice, broadband, CATV, etc. The EPON system uses upstream and downstream symmetric transmission with a nominal rate of 1.25 GB. The STANDARD of EPON is IEEE 802.3AH, which is based on gigabit Ethernet technology and realizes PON point-to-multipoint transmission through point-to-multipoint control protocol (MPCP) on MAC layer. The protocol is simple to implement, but the OAM capability is relatively weak. While the STANDARD of GPON is ITU-T G.984 series, which follows the standard protocol framework of APON and adds GEM, a new frame encapsulation method of TC layer. It has strict regulations on QoS and OAM, and has a strong capacity to carry TDM services and relatively complex protocol.  GPON has a high transmission rate and shunt ratio, providing TDM services with high timing accuracy. As for the internet fibre techno free 10G-EPON, it is developed on the basis of EPON, and the two are basically the same in technical principle, but the free 10G-EPON has a stronger carrying capacity.
