FTTH System Solutions

Background and Demand

Since China Telecom has issued 'Broadband China-Optical Network City" strategy in 2011
FTTx deployment has become the first choice of broadband access technology for tier1 level  operators in China. After years of construction, nowadays fiber broadband has become the absolute mainstream.  

As an important part of “triple play”, the broadcast television network needs the support of high-speed bandwidth networks whether it is for public broadband access or for the ultra high-definition or video service push which are growing in popularity. The increasing demand for high-speed bandwidth networks encouraging broadcast television operators to speed up the FTTH deployment.

Solutions

According to the requirements and characteristics of the broadcasting television network, Sino-Telecom has launched a package of FTTH solutions, including whole series of GPON/EPON OLT and ONU products with Sino-Telecom’s  independent intellectual property rights, WDM-PON system tailored for the situation of shortage of optical fiber resources of broadcasting television network, as well as innovative solutions including G/EPON link amplifier and G/EPON protocol analyzers to solve  interoperability problems.  These technical solutions include more than ten invention patents of Sino-Telecom.  Among them, WDM-PON solution combines WDM and PON technology, and realizes the transmission of more than 8 GPON or EPON links over a single optical fiber. With advantages of high cost performance and fast networking, it can help operators to rapidly achieve FTTH cell coverage.

1. Full Series OLT/ONU

For small and medium capacity application scenarios, Sino-Telecom provides 8-port OLT: SAN3700-G8E and 16-port OLT:SAN3700-G16E, which are 1U pizza boxes with compact size for easy and rapid deployment.

For large capacity application scenarios, Sino-Telecom launched SAN3700 10U OLT, which allows insertion of 14 16-PON port service boards and supports a maximum of up to 224 PON ports.

3.WDM-PON

With users’ increasing demand for bandwidth and the growing number of users, there is an urgent need for expansion but shortage of optical fiber resources has become the key problems.  To solve  this problem, Sino-Telecom launched WDM-PON solution, which can realize transmission of 8 PON links over a single optical fiber with respectively configuring a WDM-PON device on CO and client sides and without any  need to change the existing network infrastructure. The transmission distance can be up to 50KM.

4.G/EPON Protocol Analyzer

During actual FTTH deployment, operators usually purchase OLT and ONU devices from different manufacturers. As a result, interoperability problem usually occurs and causes great deal of inconvenience to operators’ during service expansion and network operation and maintenance activities. To solve these problems, Sino-Telecom developed XPA2000 G/EPON protocol analyzer which helps quickly identify technical issues making OAM personnel to resolve problems quickly. And these products have been installed and approved by big operators like China Telecom, Huawei and ZTE etc.

5.G/EPON Link Amplifier

For long-distance G/EPON transmission, Sino-Telecom released an affordable PON amplifier solution. GA3302/EA3302 can extend the transmission distance to up to 50KM.

Successful Cases

Sino-Telecom’s FTTH products have been widely used in domestic and foreign markets. In domestic market, the products have been widely installed and used by large operators such as China Telecom and China Broadcasting Television. In international market, our products have been sold to more than 30 countries including   Russia, Spain, India, Iran, Bangladesh and other developed & developing countries.
