It’s simple to install and manage without IT experience.' Simon Williams, Ice and A Slice. This article provides an up-to-date survey of hybrid fiber-wireless (FiWi) access networks that leverage on the respective strengths of optical and wireless. We no longer have productivity or bandwidth issues. Add more access points to give you wider coverage. After discussing the economic impact of broadband access and current worldwide deployment statistics, all the major legacy wireline and wireless broadband access technologies are reviewed. The reach of a GPON network can be as high as 60 km, whereby the differential reach between optical network units (ONUs) must not exceed 20 km. Wifi access points allow all your digital devices to connect to the network. The evolution of broadband access networks toward bimodal fiber-wireless (FiWi) access networks, described in this book, may be viewed as the endgame of broadband access. Several upstream and downstream data rates are specified for GPON, with a maximum data rate of 1.244 Gb/s in the upstream direction and 2.488 Gb/s in the downstream direction. Integrated fiber-wireless (FiWi) access networks provide a powerful platform to. The upstream and downstream wavelength channels operate at 1310 nm and 1490 nm, respectively. GPON deploys two different wavelength channels for upstream and downstream communication. These extended capabilities of GPON are explained in greater detail in the following.įigure 3.1 shows the architecture of a GPON network (Effenberger et al. To help identify open key research challenges for NG-PONs and converged FiWi broadband access networks, it is important to consider emerging trends in related areas in order to shift the post NG-PON2 research focus from mere capacity provisioning to more lucrative solution offerings by developing holistic groundbreaking solutions across. Compared with its predecessors, GPON provides larger splitting ratios, higher up- and downstream data rates, longer reach, improved privacy and security through the use of the Advanced Encryption Standard (AES) algorithm, and a new GPON encapsulation method (GEM) to carry synchronous voice services and data services such as Ethernet in a bandwidth-efficient manner (Shumate ). GPON extends the capabilities of its two predecessors, asynchronous transfer mode (ATM) PON, also known as APON, and broadband PON (BPON).

The gigabit passive optical network (GPON) is an outcome of the full service access network (FSAN) alliance and is specified in the ITU-T G.984.x series of recommendations, which were finalized in February 2004.
