一、Product Overview

In order to supply much higher bandwidth to users, telecom operators have already upgraded the ADSL2 + network to VDSL2 network step by step. But the VDSL2 bit-rate decreased rapidly with the increase of distance.

The VDSL2 Extender is installed on the loop between the VDSL2 DSLAM and the user’s modem, amplifying VDSL2 signal, extending the coverage of VDSL2 effective bandwidth, improving the downstream bit-rate and bring more stable and reliable VDSL2 broadband service to those longer users.

 

二、Features and Benefits

◎ Fully compatible with ITU-T G.993.2, G994.1

◎ Fully compatible with all the VDSL2 equipments which comply with these above standards 

◎ Fully compatible with VDSL2 band profile:8a,12a,17a,30a;PSD mask:EU32,EU64 

◎ With two kind of power supply: remote power supply and PBX line power supply

◎ With completed construction, 1, 4, and 8 lines, thess enclosures meet IP66

◎ Comprehensive over-voltage protection.

◎ Low power consumption and more environmentally friendly

◎ At 2.0 Km ~ 2.7 Km (24AWG) distance range, downstream bit-rate has increased significantly with the highest increase of 60%

◎ With easy and quick installation, no switch to config

◎ This solution is a cost-effective, quick-to-market solution
