Optical Transport Network (OTN) 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 the demand for OTN-enabled devices rapidly increasing, so does the need for an integrated OTN test equipment. The IQS-8120/8130 Transport Blazer modules offer OTN test capabilities for verifying ITU-T G.709 standards compliance. 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
• ODUflex with Ethernet client signal mapping
• Over-clocked OTU2 rates: OTU1e (11.0491 Gbit/s), OTU2e (11.0957 Gbit/s), OTU1f (11.2701 Gbit/s) and OTU2f (11.3176 Gbit/s)
• Unframed optical signal testing at 10.7 Gbit/s, 11.0491 Gbit/s, 11.0957 Gbit/s, 11.2701 Gbit/s and 11.3176 Gbit/s rates
• Synchronous mapping of SONET/SDH signals within OTN as well as synchronous and asynchronous demapping
• Forward error correction (FEC) testing
• Service disruption time (SDT) measurements
• Multichannel SDT measurements and real-time error/alarm monitoring for all ODU0 channels

• ODU multiplexing alarm-generation and analysis
• Through mode analysis
• Intrusive Through mode

• 10 GigE LAN mapping into OTU2 using GFP-F

Multichannel VCAT Testing

The IQS-8120NG/8130NG Transport Blazer’s virtual concatenation functionality supports real-time multichannel testing, allowing for each low-order (e.g., VT1.5, VT2, VC-11, VC-12) or high-order (e.g., STS-1/3, VC-3/4) path of a configured virtual concatenation group (VCG) to be controlled and monitored independently. This provides full visibility of all path errors and alarms per VCG member, critical for VCAT circuit troubleshooting. In addition, this multichannel visibility provides a means of generating simultaneous alarms and errors per member, ideal for lab verification applications, network simuation testing or device qualification.

Scalable, High-Performance Testing

Next-Generation SONET/SDH Testing

The available suite of next-generation SONET/SDH test functionalities include generic framing procedure (GFP), virtual concatenation (VCAT) and link capacity adjustment scheme (LCAS). These options are available on the IQS-8120NG/8130NG modules when housed in the IQS-600 Integrated Qualification System.

Ethernet Add/Drop Interface

In addition to its internal PRBS generator, each IQS-8120NG and IQS-8130NG Transport Blazer module includes one 10/100/1000M Ethernet (RJ-45) and one Gigabit Ethernet (SFP) interface. These interfaces can be used to interconnect with an IQS-8510B Packet Blazer Ethernet Test Module or an external Ethernet device (e.g., switch, router, etc.), delivering the industry’s first data-integrated next-generation SONET/SDH test solution for advanced Ethernet-over-SONET/SDH service emulation and analysis—ideal for verification lab test applications.

Multiservice QoS Testing for Next-Generation MSPPs

The latest generation of multiservice provisioning platforms (MSPPs) are the heart of today’s next-generation SONET/SDH networks. EXFO’s IQS-8120NG/8130NG Transport Blazer test modules, in conjunction with the IQS-8510B Packet Blazer Ethernet test module, allow for the generation and analysis of multiple Ethernet test streams over a GFP-enabled SONET/SDH link. Each stream’s quality-of-service setting is user-configurable (via IP TOS, Diffserv, Ethernet 802.1 priority bits), providing a means of prequalifying delivery of multiple services over their multiservice provisioning platforms (MSPPs) and corresponding next-generation SONET/SDH networks.

SmartMode: Real-Time Signal Structure Discovery and Monitoring

EXFO’s IQS-8120/8130 Transport Blazer modules support a unique feature called SmartMode. This provides users with full visibility of all high-order (STS/AU) and low-order (VT/TU) mixed mappings within the incoming SONET/SDH test signal.

SmartMode automatically discovers the signal structure of the OC-n/STM-n line including mixed mappings and virtual concatenation (VCAT) members. In addition to this in-depth multichannel visibility, SmartMode performs real-time monitoring of all discovered high-order paths and user-selected low-order paths simultaneously, providing users with the industry’s most powerful SONET/SDH multichannel monitoring and troubleshooting solution. Real-time monitoring allows users to rapidly troubleshoot software problems, saving valuable time and minimizing debugging time. SmartMode also provides onetouch test case start, allowing users to quickly configure a desired test path and SmartMode specific reporting.

Unsurpassed Configuration and Operational Flexibility

Next-Generation SONET/SDH Testing

EXFO’s Transport Blazer series offers four hardware configurations:

• IQS-8120 supports SONET/SDH and OTN test functions to 2.7 Gbit/s
• IQS-8130 supports SONET/SDH and OTN test functions to 11.3 Gbit/s
• IQS-8120NG supports next-generation SONET/SDH and OTN test functions to 2.7 Gbit/s
• IQS-8130NG supports next-generation SONET/SDH and OTN test functions to 11.3 Gbit/s

Product Option Flexibility

The Transport Blazer series is highly configurable and it affords customers the flexibility to customize their testing needs. Base SONET/SDH/OTN-only configurations can be easily upgraded to next-generation test functions as new needs arise. This eliminates the need to perform complete hardware and/or platform retrofits, therefore significantly decreasing capital and training expenses.

With the IQS-8120NG and IQS-8130NG Transport Blazer modules, have the choice of purchasing one or more next-generation options (e.g., GFP, VCAT, LCAS) to create a custom configuration to suit their testing needs. At any point, additional next-generation options are available via simple on-site upgrades.

Remote Management

The IQS-8120/8130 Transport Blazer modules, through their optional Visual Guardian LiteTM management software, allow users to perform remote testing and data analysis, as well as remote monitoring via standard Ethernet or remote dial-up connections.

Automated Test Scripting

The IQS-8120/8130 Transport Blazer modules support two methods for automated test scripting. First, by using industry-based SCPI commands, and second, by using a built-in macro recorder that facilitates the recording of test actions and allows to automatically create test scripts. These test scripts can be used as the basis for larger automation routines that can be created in any .NET environment.

Test Logger and Reporting

EXFO’s IQS-8120/8130 Transport Blazer modules support a detailed test logger and test reporting tools, enabling users to view any errors/alarms that occurred during the test interval, which can then be used for post-processing results or SLA conformance validation.

IQS-600 Integrated Qualification System

The IQS-8120NG/8130NG Transport Blazer modules are housed in the IQS-600 Integrated Qualification System, a scalable modular rack-mount platform that houses a controller, expansion units and a comprehensive range of plug-in test modules ideal for manufacturing, lab and R&D environments. The IQS-600 platform offers up to ten slots that can support any combination of modules from EXFO’s full range of industry-proven protocol and optical test modules. Systems can be expanded to support up to 100 test modules. The IQS-600 family is comprised of the IQS-610P, a ten-slot control unit that can support up to nine IQS-610E 10-slot expansion units, and the IQS-605P, a five-slot control unit with an integrated touchscreen.

Combined with the built-in IQS Manager software, the IQS-600 platform provides an easy-to-use environment to manage your modules, configure your system, launch applications and analyze results. The IQS-600 is supplied with LabVIEW drivers and ActiveX/COM interfaces. What’s more, it can be controlled using local applications or through GPIB, RS-232 or Ethernet interfaces.
