Abstract:
The one important in a passive optical network
(PON) for high-speed communication is fault detection and fault
alert due to the troubles of passive optical fiber or passive optical
devices. Any failure of optical devices in the optical link can
influence to a huge amount of data loss in the optical network.
However, deployment of fault detection and alert devices or
systems is extremely limited due to the financial implications
and reliability of the devices or systems. Thus, this work
proposes a design and implementation of a cost-effective way for
detection when an optical link has a fault in a PON. Also, real-time
wirelessly alert to a responsible person. This monitoring
technique is based on bidirectional light-wave communication
with single-core single-mode optical fiber and internet of things
(IoT) technology. Which consists of 2 sub-systems namely the
transmitter of the optical fiber monitoring system (OFMS-Tx)
is located at the optical network unit (ONU). And the receiver of
the fiber monitoring system (OFMS-Rx) is located at the optical
line terminal (OLT). Both parts operating with
microcontrollers, which the OFMS-Tx microcontroller uses for
generating a monitoring signal that depends on situations such
as normal operation situation or power outage situation. The
OFMS-Rx microcontroller act as a monitoring signal decoder
for the decision of the OFMS-Tx and optical link situations.
Also, OFMS-Rx real-time alerts to responsible person when
fault occurring, such as optical link fail or ONU power outage.
From experimental results show that the proposed system is
automatically working for real-time optical fiber link detection
and immediately alert to the responsible person within 11
seconds when a fault occurs. Also, the proposed system could
transmit a monitoring signal in the network over a fiber distance
of 70 km.
