Network Transmission

Method of optimizing the optical network transmission in access network has been investigated in many years. Unidirectional optical transmission system is the earliest method of delivering the information. In recent years, bidirectional optical transmission system is the most popular network and shall be the first right of refusal to deploy nowadays. It is justify enough by the massive deployment of the popular state-of-the-art network named Passive Optical Network (PON) in Fiber To The Home (FTTH) technologies. Combining 3 wavelengths includes (1) 1310nm, (2) 1490nm, and (3) 1550nm within a fiber is the method used on Gigabit Capable Passive Optical Network (GPON) or Gigabit Ethernet Passive Optical Network (GEPON/EPON). Combining 2 different wavelengths for uplink and downlink on Small Form Pluggable (SFP) lasers also has been a method used to optimized and saved the fiber infrastructure. Compared those techniques, the research optimization focusing on introducing a passive optical duplexer that combined the same wavelength from both end with the element of monitoring via different wavelength to confirm the network availability. In the design, a unidirectional converter able to operate at a nominal 1310nm or 1550nm windows shall be demonstrated up to 10Gbps Ethernet signal.

Point To Point

In the last mile of optical access network, FTTX such as fiber-to-the-cabinet, curb, building, home and node construction cost per subscriber has always been a concern for the network operators. In order to cost down the fiber and transceiver deployment, passive optical network (PON) are developed to replace active point-to-point (P2P). Also the splitter placement problems are issued that make efforts to reduce fiber and splitters deployment cost. Cost down the optical components in PONs is one of the successful elements for building the business of fiber-to-the-home (FTTH). For an example of insertion loss (IL), a traditional 1x12 splitter module which is cascaded by one piece of 1x2 (67%:33% power ratio, 2.6dB:6.2dB IL) and 10 pieces of 1x2 (50%:50% power ratio, 3.7dB IL) splitters, the IL of module is 2.6+3.7x3=13.7dB. An economical and innovative 1x12 splitter module presented in this paper could be cascaded just by one piece of 1x3 (IL: 5.4 dB) and 3 pieces of 1x4 (IL: 7.2dB), the IL of module will be 5.4+7.2=12.6dB, 1.1dB less than the former. In the case of 1x36, an innovative one is cascaded by 4 pieces of 1x3 and 9 pieces of 1x4 splitters (IL: 18dB) to replace the traditional one which is cascaded by 35 pieces of 1x2 splitters (IL: 19.9dB). Another case of 2x24, an innovative one is cascaded by 1 piece of 2x2, 2 pieces of 1x3 and 6 pieces of 1x4 splitters (IL: 16.3dB) to replace the traditional one which is cascaded by 1 pieces of 2x2 and 22 piece of 1x2 splitters (IL: 17.4dB). Finally, bundle with less IL, the economical multi-output splitter module can be successfully built up by this novel fiber coupler manufacturing apparatus and method.

Selection Of

To find out the need for fiber optic access network devices from NOC to rooms at Udayana University, Sudirman Campus, fiber to the home network design was made with Gigabit Passive Optical Network (GPON) technology. Selection of GPON technology to reduce the number of ports on OLT and the number of fiber cores compared to the existing technology using point to point. Assuming the bitrate in each room is 21 Mbps and 291 rooms to be served, it takes 5 OLT ports on the NOC. Feeder Cable Network consists of 5 cores distributed to each location using 3 units of 1: 4 splitter, 4 units of 1: 8 splitter, 6 units of 1:16 splitter, 1:32 splitter of 6 units. To maintain service quality, 16 amplifiers are needed. The required fiber cable length is 2.5 km. The quality of service is tested using the Optisystem simulator. The result is that at the closest distance the PRx value is -14.059 dBm, with BER 6.13608 e-103, Q Factor 21.511. Meanwhile, at the farthest distance, the PRx value is -14.105 dBm, with BER of 1.52751 e-120, and Q Factor 23.3159. The results obtained still meet the ITU-T G.984.2 standard

Dynamic Bandwidth

The advantages of Ethernet passive optical network (EPON) are setting it to be a natural ubiquitous solution for the access network. In the upstream direction of EPON, the directional property of the splitter requires that the traffic flow be mitigated to avoid collision. A dynamic bandwidth allocation (DBA) scheme is desirable in optimizing the bandwidth usage further. In this paper, a global priority DBA mechanism is discussed. The mechanism aims to reduce the overall delay while enhancing the throughput and fairness. This study was conducted using MATLAB where it was compared to two other algorithms in the literature. The results show that the delay is reduced up to 59% and the throughput and fairness index are improved up to 10% and 6%, respectively.

AbstractNowadays, bandwidth demand is enormously increasing, that causes the existing passive optical network (PON) to become the future optical access network. In this paper, next generation passive optical network 2 (NG-PON2) based, optical time division multiplexing passive optical network (OTDM-PON), wavelength division multiplexing passive optical network (WDM-PON) and time & wavelength division multiplexing passive optical network (TWDM-PON) systems with 20 Gbps (8 × 2.5 Gbps) downstream and 20 Gbps (8 × 2.5 Gbps) upstream capacity for eight optical network units has been proposed. The performance has been compared by varying the input power (−6 to 27 dBm) and transmission distance (10–130 km) in terms of Q-factor and optical received power in the presence of fiber noise and non-linearities. It has been observed that TWDM-PON outperforms OTDM-PON and WDM-PON for high input power and data rate (20/20 Gbps). Also, TWDM-PON shows its superiority for long-reach transmission up to 130 km, which is a cost-effective solution for future NG-PON2 applications.
