Overview

The B1-L-DSL is a compact, low-power VDSL2 Ethernet extender built for long-distance (up to 3000m) networking over existing 2-wire cabling, including standard telephone lines. Supporting 74 Mbps upstream and 74 Mbps downstream max bandwidth, it’s ideal for installations where space is limited, power efficiency is critical, and rewiring is impractical. Whether upgrading older ADSL systems or linking remote devices, it delivers stable, high-speed connectivity in a small, energy-conscious design.

Key Features

1.Compact form factor for easy installation in space-constrained environments

2.Low power consumption for energy efficiency and reduced operating costs

3.Extend Ethernet up to 3000 meters over 2-wire or telephone lines

4.74 Mbps upstream + 74 Mbps downstream for smooth video, data, and VoIP

5.VDSL2 modulation with QAM and DMT for strong, interference-resistant performance

6.FDM technology allows simultaneous voice and data transmission

7.Simple DIP switch for local/remote configuration—no software needed

8.Transparent transmission mode for full protocol compatibility

9.Multiple mounting options: desktop or wall-mount

10.Interfaces: Phoenix terminal (2P), RJ45 ports, DC 5mm power port

11.Standards compliant: IEEE802.3, IEEE802.3u, IEEE802.3ab

12.12VDC power input for easy integration with existing low-voltage power sources
