An OTU4 mapping option for Anritsu's MD1260A 40/100G Ethernet Analyzer that extends the overall measurement capability of the instrument enabling it to be configured to conduct analysis for 40GE, 100GE, OTU3 and OTU4.
This provides manufacturers of telecommunications and transport equipment, as well as network operators with a single-instrument solution that can assure the quality of high-speed networks forming the foundation of next-generation networks (NGNs) used in cloud computing applications.
The option allows the MD1260A to support GMP (Generic Mapping Procedure) mapping with Ethernet client signals at OTU4 rates for Gigabit Ethernet, 10GE and 100GE client signal types to evaluate if GMP mapping is being conducted properly.
It also supports all error and alarm testing at OTU, ODU, GMP, GFP-T and client layers, as well as has a client-signal adjustable clock offset at OTN frame payload. With the option, the MD1260A is the only single-instrument analyzer that can verify MUX/DEMUX and clock tolerance between OTU4 and Ethernet.
Additional capabilities for the MD1260A for OTU3 and OTU4 applications include an OH manipulation feature allows all OTN OH, including TCMi, TTI, and FTFL, to be monitored and edited. Additionally, OH, OTN frame and GMP can be captured for 512 OTN frames. Each OH group can be displayed as a multi-frame image, making it simple for users to identify any change in OH values.
Three types of through mode at the OTN rate are now supported by the MD1260A. The analyzer can inject random error in accordance with 0.182 to verify GFEC decoder performance, as well as support proper FEC using the OTN through mode. With this feature, users can also manipulate the OTN OH on real network data to evaluate network behavior during monitoring.
The MD1260A also conducts 40/100G tolerance tests that exceed IEEE/ITU-T standards up to +/-120 ppm at CAUI. A new service disruption time measurement (SDT) feature supports testing of the time when no frames are received, such as when there is route switching due to a fiber break.
An operation log function generates remote commands automatically from the GUI, which reduces development time for automatic tests. The MD1260A also has a flash drive, and is compact and lightweight, making it well suited for the most difficult test sites.
