The number of broadband users has reached to 678.6 million in 2013, increasing 40 million worldwide, according to the latest data released by NGO Broadband Forum. Meanwhile, data from market research company Point Topic shows that although copper-based broadband access technology is still dominant, fiber-optic broadband access technology deployment is growing very fast, including fiber to the home (FTTH) and fiber to the building (FTTB).

In order to meet the increasing demand for broadband access bandwidth, PON technology keeps innovating in two directions. One direction is to elevate the single wavelength transmission rate, which is GPON->XG-PON in ITU-T's opinion (or EPON->10G EPON in IEEE's opinion). Another direction is to use multi-wavelength multiplexing to extend aggregation speed, which is NGPON2 in FSAN's opinion.

In 2012, FiberHome's XG-PON system has passed the IOP tests of FSAN and CTC based on the AN5116-06B platform. Up to 64 XG-PON ports can be provided.

In the past three years, most operators all over the world, especially in Asia Pacific, have chosen GPON to deploy high bandwidth broadband networks. Over hundreds of millions of subscribers are now enjoying FTTx services.

FTTH has encountered many problems, especially construction difficulties and a long ROI period, due to point-to-multipoint passive optical networks and the "step" of high bandwidth advantages favored by operators. This is an impediment to FTTH permeability and dampens the enthusiasm of operators for network construction. Therefore, operators and equipment vendors have been thinking about how to tap the potential of copper wire again.

While FTTH is mainly deployed in new districts, FTTB is more suitable for old district reconstruction. Vectoring Technology, developed for VDSL2, can achieve 100M bandwidth speeds in a short distance (300 meters). G.fast Technology allows users to obtain 1Gbps bandwidth speeds. It is expected to be commercialized in 2015.

Further, 10G EPON technology is ready for commercialization, with the domestic construction volume passing 400,000 lines. In the case of making full use of existing copper resources, this can provide bandwidth up to 20M with its 10x bandwidth of 1G PON and large splitting ratio.
