DLS 8100 VDSL Wireline Simulator S P E C I F I C AT I O N S The DLS 8100 is Spirent Communications DLS Systems latest wireline simulator. Designed specifically for testing VDSL equipment up to 30 MHz, the DLS 8100 is the only product on the market capable of providing the necessary bandwidth, along with full simulation of propagation delay, phase and attenuation effects. Delivering high-speed data, voice and video to a subscriber over a single pair of wires requires pushing the limits both of circuit design and algorithms for data compression, error correction, and echo cancellation. You can test these features, and more, with the DLS 8100. To ensure that your test data carries the weight it deserves, the DLS 8100, as with all DLS Systems simulators, is compliant to national and international standards. The DLS 8100 combines simulation of the DC path and the VDSL signal path. The unit is fully bi-directional, with all cable characteristics being accurately simulated. Using a unique circuit design, the DLS 8100 realistically simulates real cable without the inherent limitations of digital signal processing. The DLS 8100 reproduces all balanced impedance, propagation delay, phase, and attenuation effects, giving you precise, accurate testing for all your applications. The unit has been designed to ensure that the effects of bridged taps, mismatches, and reflections are all present. In designing the architecture of the DLS 8100, DLS Systems has applied the experience acquired from 15 years in the simulation industry. You get a solid test platform from a company you can trust to deliver the very best. The DLS 8100 control software is PC based and links the PC to the DLS 8100 via an IEEE 488 or RS-232C interface. With easy to read visuals and pull down menus, the DLS 8100 software makes setting up a desired loop quick and easy. The DLS 8100 simulates the VDSL0 or Null loop, VDSL1 loop, and the VDSL1 loop with bridged tap in conformance to the ANSI Draft Technical Report on System Requirements for VDSL (VDSL SR:98-043R6). Loop VDSL0, or null loop, uses relays to create a zero length loop allowing the performance of the null test. DLS 8100 - VDSL Wireline Simulator Loop VDSL1 simulates twisted pair wire type TP1 and TP2, as defined by the ANSI committee. TP1 is similar to USA standard 26 AWG cable and European 0.4 mm cable, while TP2 is similar to USA standard 24 AWG cable and European 0.5 mm cable. The loop can be incremented from 700 – 5150 ft in 50 ft steps or extended out to 8150 ft in 50 ft steps. Loop VDSL1 with Bridged Tap simulates the VDSL1 loop for TP1 and TP2 as defined by the ANSI committee, with the addition of a 50 ft bridged tap at one end. This simulates the cable topology often found on user’s premises. Extended Noise Injection ports are available for the input of Common Mode noise and Differential Mode noise, at either end of the simulated loop.
