In this paper we share an experience on managing the Fiber-to-the Home (FTTH) network for next generation customer access network. We ensure our proposed network system able to localizing the failure that occurs at end user by means of our new concept prototype device. Detecting fault on traffic with carried by the same wavelength is an obstacle due to the single photo-detector used but with our proposed configuration we are able to detect the fault and location specifically. Additional, we developed also the prototypes for easiness maintenance for the future implementation. Finally we show excellence results to indicate our proposed system is the better proposal for new generation network with survivability and effective monitoring solution.

“…As the move of FTTH network, survivability or robustness of FTTH system has become an important issue [12][13][14][15][16][17][18][19][20][21][22][23][24][25]. From the view point of implementing methods for enhancing the survivability of FTTH system, we can divide the research works into two parts roughly.…”

“…The other part of the reported researching works paid attention on the design of monitoring systems for de tecting and failure identification with the assistant of OTDR (Optical Time Domain Reflectometry) [21][22][23][24][25]. A Passive In-line Monitoring (PIM) device prototype was proposed, which used to tap out a small ratio of triple-play signals for in-service monitoring and failure identifying against fiber fault in FTTH network [21].…”

Triplexer was one of the key components in FTTH systems, which employed an analog overlay channel for video broadcasting in addition to bidirectional digital transmission. To enhance the survivability of triplexer as well as the robustness of FTTH system, a multi-ports device named triplexer monitor was designed and realized, by which failures at triplexer ports can be detected and localized. Triplexer monitor was composed of integrated circuits and its four input ports were connected with the beam splitter whose power division ratio was 95:5. By means of detecting the sampled optical signal from the beam splitters, triplexer monitor tracked the status of the four ports in triplexer (e.g. 1310 nm, 1490 nm, 1550 nm and com ports). In this paper, the operation scenario of the t riplexer monitor with external optical devices was addressed. And the integrated circuit structure of the t riplexer monitor was also given. Furthermore, a failure localization algorithm was proposed, which based on the state transition diagram. In order to measure the failure detection and localization time under the circumstance of different failed ports, an experimental test-bed was built. Experiment results showed that the detection time for the failure at 1310 nm port by the triplexer monitor was less than 8.20 ms. For the failure at 1490 nm or 1550 nm port it was less than 8.20 ms and for the failure at com port it was less than 7.20 ms.

“…Survivability is the capability of the system to preserve the service in the case of component breakdown sech as devices and optical cable (Ab-Rahman et al, 2011). Noted that survivability in FTTH network is an important issue because it has been discussed in optical network by earlier studies (Yeh and Chi, 2008;Aziz et al, 2009;Premadi et al, 2010Hossain et al, 2005Zhao et al, 2005). The concept has also been extended in WDM-FTTH network (Han et al, 2007;Chan et al, 2003).…”

Problem statement:This study highlight on restoration scheme proposed against failure in working line at the drop region for Fiber To The Home (FTTH) with a Passive Optical Network (PON). Whereas PON is a system that brings optical fiber cable and signals all or most of the way to the end user. In this study we highlighted the issue on survivability scheme against failure which is focused scattered residence architectures. Approach: Two type of restoration scheme is proposed by means of linear protection (tree) and migrate protection (ring). Our proposal scheme is inexpensive and applicable to any residence architecture (ordered placement and scattered placement). The advantage of this scheme is the failure at fiber line can be recovered until two levels to make sure the optic signal flow continuously. FTTH based network design is simulated by using opti system 7.0 in order to investigate the power output and BER performance at each node in the tree and ring protection scheme in scattered placement to prove the system feasibility. Results: Computation of Channel Dissipation on Each Breakdown Condition has give the insertion for 16.4 dB (normal condition), 18.8 dB (failure order 1), 21.2 dB (failure order 2) and 23.6 dB (failure order 3). Simulation was carried out to study the maximum distance that can be achieved for signaling path in two situations which are; in normal and breakdown condition with the restoration scheme. The sensitivity that used in analysis to study the maximum fiber length is -25, -30 and -35 dBm. The result shows output power that linearly decrease as the fiber length is increased; for four breakdown condition in this protection network. The highest output power achieved by normal condition at each increase in distance compared to the output power at level 3 breakdown. In addition, the accessibility of maximum distance is dependent on the sensitivity used. In order to achieve a high fiber length of more than 20 km −1 at third level breakdown, the proposed sensitivity should exceed -33 dBm. It is based on output power at third level breakdown that recorded at -32.502 dBm (1490 nm) for orderly placement of this protection network. Conclusion: This study suggests the migration of tree to ring topology to enable the signal flow continuously in the case of failure occurs specifically in random or scattered placement topology. Our proposal is the first reported up to this time in which the upstream signal flows in anticlockwise in ring topology when the restoration scheme activated.
