POL All-optical Access Solution To School Network Application

Background and analysis
As the rapid development of school’s data services, it turns to be more obvious that network’s capacity and performance can’t meet the demand of school’s development better. In terms of school network, the situation is, Numbers of Ethernet switches needed, Chaotic layout of integrate wires, Serious energy consumption in computer room, and Limited bandwidth. As a result, it brings a series of issues like Propagation delay of Internet signals (Because it needs passing through more network nodes), Complex network structure, Multiple network levels, Difficult location and maintenance of faults, Expensive copper cables, Multiple levels of equipment, Difficult transformation, and High costs of upgrade and update. School network adopts gigabit backbone network, but it only provides wireless coverage for some areas. To a large extent, teachers and students have been influenced by limited network resources. Modern school networks need to be high-speed and interconnected, stable and reliable, convenient and manageable, safe and under control. Based on the situation of modern school network, V-SOL Tech has launched a POL All-optical Access Solution To School Network Application.

POL (Passive Optical LAN) is a passive all-optical LAN. It is a new LAN networking solution based on PON technology. It inherits the advantages of PON network like More Bandwidth, More Reliability, Flatness, Better Deployment, and Better Management, etc. At the same time, POL solution fully adapts to the characteristic requirements of school LAN, such as 802.1x authentication, POE, etc. It shows the ability to be commercialized on a large scale of school.

Detail of solution
The POL of V-SOL Tech adopts the GPON solution architecture. The OLT is the aggregation network element, and it is deployed in the core computer room. From the core computer room to users, the middle layer adopt a passive optical splitter, which does not require independent computer room deployment and power supply. The ONT is close to users and is connected to users through a copper wire.

In response to the needs of school network construction, V-SOL Tech thinks about the high population density of school. V-SOL has deployed High-tech and cost-effective OLT equipment (V1600G2/V1600G1), which can achieves the function of access and aggregation in the core computer room. With passive ODN network, V-SOL helps school complete network coverage from fiber to desktop, different kinds of access terminals ONU (ICT3310DPS, etc.). These meet users’ access demand of high-speed Internet, IPTV, etc., and can also make it possible to achieve video surveillance, school smart card and other services.

In order to help teachers and students experience unobstructed wireless Internet access, V-SOL makes cooperation with system integrators and China Mobile and adopts the solution of ONU external AP that supports POE power supply, to provide flexible billing methods such as Portal, WeChat, and authentication payment of SMS multi-dimensional access.


VSOL happy that our products XGS-PON serve all over the world
