Applications driving demand for next-gen PON

Four major application areas are driving next-gen PON development and standardization.  FTTBuilding for multi-dwelling units (MDUs) – In these deployments, next-gen PON would provide more bandwidth to be shared among the units in the building.  Enterprises – Next-gen PON would provide enterprises with more upstream bandwidth, supporting video conferencing and cloud-based file backup, […]

The advantage of TWDM PON

With the completion of lab trials this year, commercial trials expected in 2015, and initial deployments forecast for 2016, TWDM PON (time wavelength division multiplexing passive optical networking) is on the horizon. While today’s PON meets the requirements of residential subscribers, small-tomedium-sized usinesses (SMBs), and some MBH (mobile backhaul) applications, CSPs (communications service providers) want […]

Optical Splitter

In 2012, a leading market and technology analysts announced the Asia Pacific region (APAC) region leads in the consumption of Planar Lightwave Circuit (PLC) splitter compact devices with 68% of the worldwide value, followed by the American region and finally the EMEA region. The increase of mass FTTx PON network deployment dominates the worldwide PLC […]


WDM-PON Technology

WDM-PON Technology A typical wavelength division multiplexing PON (WDM-PON) architecture is shown in Figure 4-1. The wavelength division MUX/DEMUX is employed in the ODN. In the example in Figure 4-1, array waveguide gratings (AWGs) are used to MUX and DEMUX wavelengths to or from ONUs. Signal transmission in WDM-PON is similar to that in the […]


Hybrid GPON/G.fast distribution point unveiled by Telnet Redes Inteligentes

Telnet Redes Inteligentes S. A. has introduced a Hybrid Fiber-Copper Access Distribution Point (HFCA-DP). The platform is the first to combine GPON and G.fast distribution point equipment (DPE) capabilities in a manner fully interoperable with Alcatel Lucent and Huawei GPON optical line terminals (OLTs), the company asserts. The DPE also can be used in WDM-PON […]
