Reza Vaez-Ghaemi. Introduction The increasing need for residential triple-play, wireless broadband, and IP business services continues to drive the demand for network expansion in core metro networks. However, Ethernet and DWDM lack some key characteristics necessary for carrier-grade performance and management in metro core networks.

Optical Transport Network OTN technology delivers superi- or reach, transparent transport of client signals, and powerful switching and management capabilities. This white paper provides an introduction to OTN technology and focuses on test and measurement applications for OTN-related field deployment. In long-haul networks Figure 1 , the reduction of regenerators and transponders constitutes a significant component of cost savings.

A client-server model is applied between sublayers of the OTN. Each sublayer offers well defined services to its client layers and each sublayer has its own layer management functions, including fault, performance and configuration management. Link synchronization test shall be performed ahead of optical power test.

An optical attenuator can be used in series with the device under test DUT. While measuring bit error rate BER , the applied optical signal is continuously attenuated until the threshold of the OTN receiver is reached.

Clock deviation is tested by applying an OTN signal and verifying the signal integrity in presence of varying frequency offset up to maximum limit. In order to verify FEC, a number of error patterns are inserted in subrows of the transmitted signal then transmitted through an OTN device under test.

As the name suggests, when inserting correctable FEC errors, the DUT should still be capable of correcting these errors. This test can verify the correct installation of network element in the field. Here, it is not possible for the errors to be corrected by the DUT. The G. The demapping function is checked in a similar way in other direction.

In addition to client frequency offset check, various payload tests can be performed. Related Papers. CD By miguel bautista. By Who I AM. By Sofian h. By Karen G Oscura. A novel algorithm to integrate synchronous digital hierarchy networks into Optical Transport Network using mixed line rates.
