ABOUT THE TIGERACCESS-EE CPE

data rate in the downstream (receive) direction than in the upstream (transmit) direction.

VDSL delivers high-performance online applications, such as high-quality video and other switched multimedia services. This Ethernet VDSL2 CPE system provides robust performance, with a symmetric data rate up to 100 Mbps, and a range up to 200 meters (656 ft).

This system is based on advanced VDSL2 Multi-Carrier Modulation (MCM) technology with adaptive channel equalization that overcomes bridge taps and other line distortions. Reed-Solomon Forward Error Correction and interleaving protects against errors due to impulse noise, and enables recovery from signal interruptions. Frequency Division Duplexing (FDD) separates downstream and upstream channels and allows VDSL signals to coexist with regular telephone services. A power back-off mechanism is also implemented to reduce noise from crosstalk in line bundles.
