DLS8110

Spirent DLS 8110 VDSL Bridged Tap Simulator DLS 8110 Growing demand for high bandwidth multimedia applications with integrated voice, data and video is one of the primary drivers for VDSL technology, the natural evolution from ADSL. To assist data rate performance testing in VDSL chipset and modem development, which are sensitive to bridged taps, Spirent Communication has launched the DLS 8110 VDSL Bridged Tap Simulator. Used with the DLS 8100 (or the DLS 8111) VDSL Wireline Simulator, the DLS 8110 helps to provide VDSL test loops that include variable bridged taps with small increments. Features Variable, long bridged tap simulation Benefits The DLS 8110 simulates the TP1 (26 AWG) bridged tap that is variable from 0 to 250 feet in 10 foot increments. Long bridged taps are important in VDSL data rate and BER (Bit Error Rate) performance testing. Increments as short as 10 feet allow the testing to be very focused in identifying access device problems. A basic VDSL loop simulation system includes a DLS 8100 chassis (or at least one DLS 8111 chassis) and at least one DLS 8110 chassis. A DLS 8100 (or DLS 8111) + a DLS 8110 system offers VDSL testloops with long variable bridged tap(s) in smaller increments. This helps to provide complex loops beyond the current VDSL standard T1E1.4/2001-009R2 and ITU-T G.993.1 (previously known as G.vdsl). The DLS 8110 and DLS 8111 combination provides continuous bandwidth from DC to 30 MHz that is essential for the testing of VDSL co-existing...
