Welcome To Telebyte Broadband

 
Model 458  Module Series
for Local Loop Simulation, Switching, Noise Generation

Related: local loop simulator / wireline simulator / ADSL / ADSL2 / ADSL2+ / ADSL2++ / ADSL2PLUS / ADSL LITE / ISDN / G.LITE / SHDSL / G.SHDSL / VDSL / VDSL2 / automated testing / white noise / noise generator / AWGN / switch matrix

  • Loop Simulation up to 36 MHz
  • Test automation through multiplexing/demultiplexing
  • Plug-In functionality
  • Provides multiple configurations
  • 2 – 8 Channels
  • Optional Noise Sources
  • Low noise floor / low crosstalk
  • One-year warranty/calibration (See Customer Care Program for details)

 

All of our reliable 458 Loop Simulators plug into our Model 458-3SLA (3-Slot Chassis) or Model 458-CC-16/458-CM (16-Slot Chassis & Control Module) to create a wide variety of test configurations. The use of high-precision inductors, resistors and capacitors facilitates full bi-directional operation at all specified frequencies. Bandwidths up to 36 MHz accommodate the latest technologies.

Also available in this format, the 458-SM-2-16 (2 x 16 Transparent Switching Module), a highly-accurate multiplexing/demultiplexing device used to automate testing of ADSL, ADSL2, ADSL2+ and VDSL2 chips, modems and DSLAMs.

Also available in this format, the Model 458-AWGN2 (Dual Output AWGN Generator Line Module) injects Additive White Gaussian Noise (AWGN) for ADSL, ADSL2, ADSL2+, and VDSL2 chip/modem/DSLAM testing applications. The user may add AWGN on the CO and/or CPE side, depending on their application.
