Digital Lightwave adds Fibre Channel over OTN, ODTU-03

Digital Lightwave Inc. says it has added support of Fibre Channel over Optical Transport Network (OTN) and ODTU-03 mapping to the OTN testing features of its flagship NIC Platform.

The ODTU-03 mapping option is supported on the NIC 40/43G module. It provides ODU-0 mappings over the physical OTU-3 (43-Gbps) interface, joining the NIC's existing capabilities of ODTU-01, ODTU-012, ODTU-12, ODTU-13 and ODTU-23. The ODU-0 can support PRBS and Null Client mappings, as well as Transcoded 1000Base-X if the NIC is also equipped with an MSA 2020/2030 module. The Transcoded 1000Base-X mapping enables ODU-0 to carry Gigabit Ethernet (as GFP-T) over OTN interfaces.

Digital Lightwave says this feature supports complete testing at all OTN levels including error and alarm generation/detection, multi-layer overhead manipulation/detection, OPU Frequency offset generation/detection, and GMP stressing/analysis, among others.

The Fibre Channel over OTN feature supports both OTU1f (11.270 Gbps) and OTU2f (11.317 Gbps) interfaces with framed (10G Fibre Channel Sync), unframed, PRBS, and Null Client mappings. It also includes service disruption measurements for OTU1f, OTU2f, and 10G Fibre Channel. The new feature complements the existing Fibre Channel test capabilities within the NIC, which includes 1G, 2G, 4G, 8G, and 10G interfaces.

The NIC MSA 2020/2030 module also supports OTU-1e (11.049 Gbps) and OTU-2e (11.095 Gbps) for testing 10-Gigabit Ethernet over OTN signals.
