OTDR automates FTTH fault management
Test & Measurement World Staff - October 16, 2012
Intended for in-service FTTH testing, monitoring, and troubleshooting, the FG-750 Node iOLM from EXFO is a specialized OTDR that performs end-to-end PON (passive optical network) testing from the central office.
The unit can test point-to-multipoint fibers or run downstream tests from the node or central office to any PON line type, providing operators with an automated, operation-oriented way of assessing the health of their FTTH networks.
The FG-750 Node iOLM (intelligent optical link mapper) allows operators to validate end-to-end fiber quality from a centralized location and throughout the lifecycle. Its ability to perform online quality control of contractual work and to further use the same equipment for isolating and pinpointing optical-layer impairments in a more automated way improves operational efficiency.
Carrier-class hardware used in the FG-750 meets FTTx network requirements, such as connection to multiple optical test ports, use of multifiber cables, low power consumption, small volume, and scalability. In addition, EXFO offers 576-port and 720-port optical-switch and test-access modules to allow in-service addition of out-of-band OTDR signals to the line under test, all from the node.
