Spirent 400301a ATM OC-3c Single Mode Interface Module
 
The Spirent 400301a ATM OC-3c Single Mode Interface Module is designed for use only within an Adtech AX/4000 Broadband Test System. This module is one of the key building blocks in high-precision testing across the ATM network, supporting both the SONET OC-3c and SDH STM-1 interfaces that enable crucial performance and QoS assessments for a wide range of transmission technologies. Operating at a data rate of 155.52 Mbps, utilizing a 1310 nm single-mode optical interface with SC connectors, this unit will be able to meet very stern demands of speed and accuracy in network testing environments.
 
The AX/4000 system into which this module integrates is a robust, modular testing platform that can support several transmission protocols like ATM, IP, Frame Relay, and Ethernet simultaneously. The AX/4000 system is targeted to meet the needs of both the telecom providers and the equipment manufacturers. Its flexible configuration allows users to assess network performance under a variety of real-world conditions. Similarly, by installing module 400301a, the user will be able to test ATM-related functionalities while continuing to ensure compatibility with the other interface modules of the platform, enhancing versatility and functionality in thorough broadband network testing.
 
The 400301a module is installed by directly connecting to the AX/4000 test module using dual SC connectors for data transmit and receive. Supported multiple clocking sources of this module are an internal oscillator, a loopback clocking derived from incoming data, or an external 155.52 MHz clock via an SMA connector. The AX/4000 module is also equipped with a Windows-based software interface, allowing deep control of the parameters to be set within customized test configurations and real-time monitoring of the key indicators, including signal integrity and error detection.
 
The field-programmable module, 400301a, is updated continuously to support evolving network protocols and evolving standards of testing. Extreme conditions can also, therefore, be carried out in conformance and stress testing. Visible LEDs on the front panel of the module immediately provide clear indicators of important measures—including data integrity and operational status—to simplify troubleshooting. For this reason, a combination of flexibility, performance monitoring, and high levels of compatibility with a wide range of network configurations makes the Spirent 400301a ATM OC-3c Single Mode Interface Module indispensable in high-quality, scalable ATM network testing.
