Development of passive optical networks (PONs)

PONs have attracted great attention in recent years, also from standardization bodies. Once again, the primary organizations are ITU-T and the IEEE (Institute of Electrical and Electronics Engineers). The latter defined the “Gigabit Ethernet Passive Optical Network (GEPON)” back in 2004 in the standard IEEE 802.3ah1. It is well known and established under the name […]

10G EPON optical transceivers drive FTTP applications

GPON and 10G EPON optical transceivers for fiber to the premise (FTTP) or FTTH Fiber to the home applications to its Passport line of universal transceivers. For GPON, SFP transceivers for both OLT (optical line terminal) and ONT/ONU (optical network terminal/Optical Network Unit) interfaces. there are also 10G EPON via both SFP+ and XFP transceivers; the SFP+ […]

Time for 10G EPONs to Shine

A 10G Ethernet Passive Optical Network (EPON) solution set enables network operators, whether they are operating public or private networks, to deliver bandwidth to users well above legacy EPON or GPON (Gigabit Passive Optical Network) rates. You might be asking yourself, “So what? Why would anyone need a 10G PON solution?” It is true that […]


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 […]

GPON GEPON Comprehensive Comparison

Initial PON (1990s) were based on ATM framing (APON, BPON), ATM-based BPON were inefficient, majority of traffic through the access network was IP traffic, Ethernet based PON (EPON), QOS-aware Gigabit Ethernet (GbE) (VLANs, prioritization, OAM) and integration with other Ethernet equipment, Gigabit-capable Passive Optical Network (GPON) proposed by FSAN members (Quantum Bridge et. al) – […]
