The ability to quickly identify and isolate network outages is critical function for any network operator. Without it, operators not only have to explain to their customers why the outage occurred, they also must compensate them for any period of service unavailability in excess of their Service Level Agreement (SLA). In an industry where Average Revenue per User (ARPU) is used as a key metric for evaluating an operator’s financial health, the ability to avoid SLA penalties has measurable impact onthe bottom line.
With the EKINOPS PM OTDR module, network operators have the ability to determine the fault location based on the reflection point of the OTDR signal. Depending on the Optical Return Loss (ORL) induced by the fiber defect, up to 65 dB round trip loss can be detected, corresponding to typically 40 kms from the terminal.
This ability allows them to dispatch technicians to the correct location saving the time and effort normally associated with locating faults such as fiber cuts. The EKINOPS PM OTDR can be deployed in multiple configurations — per-span, per-cable or long span. In a per-span application, a PM OTDR is deployed at the beginning of each span allowing each fiber — East and West — to be monitored individually:
In a per-cable configuration, a single PM OTDR module can be used to monitor two spans on a fiberpair in the same cable:
In long span applications, deploying a PM OTDR on each end provides fault detection and isolation at distances up to 80 kms, eliminating the need for mid-span access at an intermediate point without sacrificing network visibility:
The EKINOPS PM OTDR can be managed through SNMP or via the EKINOPS standard element level management interfaces, which include a CLI (CommandLine Interface) and an EKINOPS java-based GUI (Graphical User Interface). The CLI is accessible via SSH and Telnet remotely or via a local serial port locallyon the Management board.
Complete performance monitoring and management is provided, including laser shut off. Digital Diagnostics Management (DDM) is supported for the SFP interfaces. This includes link status, transmit (TX) and receive (RX) signal power monitoring, and operational temperature, as well as manufacturerand transceiver model.
The module is also supported by Celestis NMS, the EKINOPS Network Manager.
