Uni-lambda bidirectional 10∕1.25 GbE access service based on WDM-PON

Improvement Scheme for Directly Modulated Fiber Optical CATV System Performances

“…Recently, passive optical networks (PONs) are promising way to obtain low cost and high capacity optical Internet access. DWDM in combination with PON has received considerable attentions due to its large capacity, network security, easy management, and upgrade-ability (Choi et al, 2005;Hann et al, 2004;Khanal et al, 2005). In parallel with the PON systems, radio-over-fiber (ROF) transport systems also present a potential to offer significant network flexibility, large transmission capacity and economic advantage to satisfy the increasing demand in wireless broadband services such as WiMAX (Masella & Zhang, 2006).…”

Bidirectional Hybrid DWDM-PON for HDTV/Gigabit Ethernet/CATV Applications

“…A passive optical network (PON) is a promising means to obtain low-cost optical access. The use of DWDM in combination with PON has received considerable attention in many fields; it is the most promising candidate for a lightwave transport system due to its large capacity, network security, easy management, and upgradeability [1]- [4]. For the practical implementation of a DWDM-PON, finding a cost-effective light source is the key issue.…”
