1) Preface:
With the rapid emergence of various businesses, more and more industries realize that it is necessary to break through the “bottleneck” of bandwidth as soon as possible, and the optical fiber is by far the best transmission medium. Optical fiber has two advantages over the copper wire: longer transmission distance; More data is transmitted per unit time (up to 100tbps / s at present).
This course mainly studies the background, basic concepts, characteristics, application scenarios of GPON technology, the management mode of GPON system and the service distribution mode of the terminal, as well as the networking application and networking protection mode of GPON.
2) Concept
PON is a passive optical network with a point to multipoint (p2mp) structure;
GPON: Gigabit-capable passive optical network. Composition of PON network: optical line terminal (OLT)
An optical distribution network (ODN) is composed of optical splitter and optical fiber
Optical network unit/terminal onu/ont (optical network unit/ optical network terminal)
The transmission process is as follows:
OLT uplink is connected to the Internet, VoIP, IPTV, and downlink is connected to ODN;
ODN distributes all data to each ONU or ont through optical division;
ONU or ont filters out the data they need through the identification code in the data frame, and then transmits it to the user.
The above is the GPON network architecture brought by Shenzhen Shenzhen HDV photoelectric Technology Co., Ltd. The module products produced by the company cover optical fiber modules, Ethernet modules, optical fiber transceiver modules, optical fiber access modules, SSFP optical modules, and SFP optical fibers, etc. The above module products can provide support for different network scenarios. A professional and strong R&D team can help customers with technical issues, and a thoughtful and professional business team can help customers get high-quality services during pre-consultation and post-production work.
