30 MHz Copper and VDSL2 Triple-Play Services Testing
Benefit from optimal performance and flexibility for your FTTx-based triple-play services deployments thanks to EXFO’s AXS-200/635 module for the AXS-200 SharpTESTER. This test set provides you with a wide range of measurements so that no matter what stage of VDSL2 or ADSL1/2/2+ deployment you are at—prequalification, installation, troubleshooting or repair—you have all the measurement tools you need to get the job done efficiently and properly. Moreover, by keeping test cycles as short as possible, the AXS-200/635 allows you to save money; thus, positively affecting your bottom line.
The AXS-200/635 combines multilayer 30 MHz copper spectrum, VDSL2 speed verification with backward compatibility to ADSL1/2/2+ and triple-play testing—making it the only test set you need. It also enables field crews to speed up service turn-up, maintenance and troubleshooting operations by assessing the physical medium or triple-play services in a single test sequence.
Part of the SharpTESTER Access Line, the AXS-200/635 integrates the functionalities of the AXS-200/610 30 MHz Copper Test Set and the AXS-200/630 VDSL2, ADSL2+ and IP Triple-Play Test Set. This highly intuitive handheld unit allows technicians to qualify and troubleshoot the copper-loop plant and triple-play services from top to bottom with one consolidated test set.
The AXS-200/635’s bright color LCD display provides a sharp graphical user interface for showing clear results (including graphs), making it a straightforward, user-friendly test solution, perfect for triple-play services analysis. Designed for real-life testing conditions, the AXS-200/635’s display is ideally suited for use in direct sunlight thanks to its transflective color display.
You Need VDSL2 and Ethernet to Deliver HD IPTV
VDSL2’s high-speed capability not only breathes new life into your existing copper plant but it allows you to reduce churn and gain market share in delivering triple-play services to your customers. High-definition (HD) IPTV service is the killer application for VDSL2 deployment as it requires the most bandwidth and the best quality of service (QoS) that your customers have come to expect.
EXFO’s AXS-200/635 offers a quick, yet thorough method for testing triple-play services—VDSL2 and Ethernet-based data, VoIP and IPTV testing—using pass/fail-driven automated functionalities.
In addition to validating connectivity to the DSLAM, the AXS-200/635 provides upstream and downstream parameters such as actual data rates, attenuation and noise margin. What’s more, it delivers advanced IPTV measurements—packet jitter, packet loss, PCR jitter, MDI, PID viewer and IGMP zap time—both in Terminate (stand-alone) and Through mode operation. The AXS-200/635 also monitors residential VoIP call flow and statistics, facilitating VoIP QoS assurance.
Single-Ended Video and Data Rate Analysis
The AXS-200/635 single-ended video and data rate analyzer software option allows you to determine the xDSL data rates that a copper loop will support, prior to connecting/provisioning the circuit. With this new feature, you can evaluate a circuit’s ability to carry ADSL2+ bit rates at the CO or the customer premises and find out how many IPTV channels can be supported during the pre-deployment stage.
Thanks to this industry-leading option, you can:
- Prequalify and validate circuits without having to install terminal equipment
- Reduce the number of false positives (failed installs)
- Decrease the cost of identifying up-sell opportunities (customers wanting newer/faster video and network applications such as ADSL2+ and IPTV)
Impulse Noise Protection +
You need to provide your customers with comprehensive assurance against poor tripleplay services. With this in mind, the telecom industry has adopted the DSL-based impulse noise protection (INP) parameter, which is particularly important when deploying IPTV services based on VDSL2 and ADSL2+. For example, the INP helps reduce the amount of macro-blocking in an IPTV stream caused by short duration and intermittent impulse noise spikes. However, the downside of standard INP implementation is that it can limit the speed of VDSL2 (or ADSL2+) offered to customers as well as the addressable service area (distance).
The AXS-200/635 supports the traditional INP parameter as well as Broadcom’s innovative approach to INP called PhyR™. This technology allows for significantly lower BER, higher DSL rate and longer reach compared to standard INP implementations. As a result, the AXS-200/635 can be used to verify and ensure consistent QoS for DSL-based IPTV deployments without impacting speed or performance of the DSL link.
True Backward-Compatible and Interoperable Testing
Since the AXS-200/635 is based on the industry-leading Broadcom chipset, you are assured of excellent interoperability for VDSL2 and ADSL2+ when testing against other Broadcom chipset-based devices as well as other manufacturer chipsets.
Thanks to the AXS-200/635’s Broadcom chipset, you can use the Broadcom’s Nitro mode when testing ADSL2+ to effectively negotiate with DSLAM (also using a Broadcom chipset) in order to achieve data rates as high as 30 Mbit/s (depending on DSLAM setup, loop length, noise influences and circuit quality).
