Why GPON Technology is More Suitable for the Construction of the FTTH Network

The arrival of the triple play, will greatly promote the video business, such as high-definition television, as well as the future of 3D TV business rapid development of broadband services, but also broadband access network is another new challenge. FTTH can not only provide massive bandwidth support business, and low operating costs, therefore, FTTH mode will gradually become the mainstream of triple play network construction in 2010 years to achieve scale deployment. Significant advantages of FTTH.

In the past few years, carriers generally adopted EPON technology, by the large-scale deployment of FTTB/FTTN original access network of optical fibers and speed to achieve from the original 512K "narrow" broadband to 4M/8M/12M high bandwidth upgrade but with the growing popularity of high-definition television and other the severe erosion bandwidth video class of business in the next few years, due to the limited bandwidth of EPON can provide effective, as well as the number of users more brought under a single PON port existing mode will lead to the present FTTB-based access network to turn highlights powerless in the next era of full-service, bandwidth bottlenecks.

Continues to mature as the whole industry chain, the end-to-end cost of each line of FTTH has dropped to about 1,000 Yuan, has reached the scale deployment costs level, especially in the new area, FTTH FTTB cost disadvantage compared to the gradual narrow, basically reached the same level.

Taking into account the FTTH can provide massive bandwidth, business support, and the operating costs are very low, FTTH mode will gradually become the mainstream, and achieve economies of scale deployments in 2010. High quality FTTH PON equipment manufacturer, Sopto, has launched GPON/EPON/10GPON mixed interpolation solutions based on the original 7342 platform, together with a light terminal series to meet operators under different scenarios and business needs FTTH deployment.

In FTTH scenario, because GPON splitting ration can be achieved 1:128, with better network planning flexibility, mobility and bandwidth scheduling, can effectively reduce the sunk cost. GPON offers higher effective downlink bandwidth and better QoS guarantee. In addition, in the process of upgrading to the next generation 10G PON compared to EPON, GPON can achieve a smoother evolution.

GPON up and down the line wavelength, wavelength division superposition can be used, in the case does not change the current network deployment OLT / ONT / ODN smooth upgrade. Upstream wavelength and 10 GEPON and EPON overlap, so using time division multiplexing manner compatible with the existing network deployment EPON ONU, which will lead to all central office OLT line card with new the line of 10GEPON card to replace this deployment of existing network services and devices serious. Therefore, GPON technology is more suitable for the construction of the FTTH network.
