Optical Transport Network Testing

OTN as per ITU-T G.709 has recently introduced two new concepts: ODU0 and ODUflex. ODU0 is a new virtual container
of 1.25 Gbit/s bandwidth specifically defined for efficiently mapping Gigabit Ethernet services over OTN. As for ODUflex,
it is the most efficient sub-wavelength bandwidth management capability for transport line rates of 10 Gbit/s, 40 Gbit/s and
upcoming 100 Gbit/s. ODUflex allows providers to interconnect routers in ways that enable efficient bandwidth growth in steps
of 1.25 Gbit/s, eliminating the need to allocate a full fixed-rate ODU container to each connection, and allowing service providers
to transport efficiently and seamlessly across lower-cost optical infrastructures.

With OTN deployments rapidly increasing, so is the need for smaller, field-oriented OTN test equipment. The FTB-8120NGE/8130NGE
Power Blazer modules offer OTN test capabilities for verifying compliancy with ITU-T G.709 standards. The tests include:

OTU1 (2.7 Gbit/s) and OTU2

(10.7 Gbit/s) bit rates

ODU0 (1.25 Gbit/s) container with

Gigabit Ethernet and SONET/SDH
client signals mapping

Overclocked OTU2 rates: OTU1e

(11.0491 Gbit/s), OTU2e (11.0957
Gbit/s), OTU1f (11.2701 Gbit/s) and
OTU2f (11.3176 Gbit/s)
