1. VDSL

Proscend 100 VDSL2 LAN Extender is a Long Reach Ethernet Extender with one Ethernet port (RJ-45 connector) and one VDSL port (RJ-45 connector) It is a bridge mode modem, well accommodating VDSL2 (Very-high-data-rate Digital Subscribe Loop) technology to extend Ethernet service over single-pair phone line. Supporting both symmetric and asymmetric transmission, it can reach up to 100/75 Mbps bandwidth (line rate) within 300M or 10/10 Mbps (line rate) for 1 Km long range connections. By providing ultra-high speed, Proscend VDSL2 100 LAN Extender makes your telephone line achieve its best performance than before. It has the advantage of minimum installation time (simply as plug-n-play) and minimum expense by allowing video streaming and data to share the same telephone pair without interference.

The Proscend Communications VDSL Media Converter delivers everything needed to quickly deploy a high-speed IP-based network for providing high-speed Internet access, video-on demand services and voice services. The resulting compact, cost-effective form factor offers Systems Integrators, small business owners an attractive Long Reach Ethernet solution. 

Features

  • Cost effective bridge function to connect two Ethernet LAN
  • Support flow control on Fast Ethernet port via PAUSE frame or Back Pressure
  • IEEE 802.1Q VLAN tag transparent
  • Easy installation via simple plug-and-play
  • Selectable CPE and CO mode via DIP switch:
    Two working modes are built in the same unit, which keep the flexibility of installation and easy provision of service but lower inventory of service provider.
  • Selectable fast and interleaved mode:
    Fast mode guarantees a minimum end to end latency less than1 ms. Interleaved mode provides impulse noises protection for any impulse noise with a duration less than 250 us, Interleaved mode has a maximum end to end latency of 10 m sec. Interleaved mode is the default mode.
  •  Selectable target band plan:
    Symmetric: Support the band plan G.997 and provide the symmetric transmission on both down stream and upstream.
    Asymmetric: Provides highest line rate in short range in asymmetric mode.
  • Selectable target SNR margin:
    User has the ability to select fixed SNR margin (9 dB) or fixed target data rate. When fixed SNR margin is selected, the systems will maintain the SNR margin at 9 dB across all usable loop length. When fixed target data rate is selected, the system will lock the data rate up to 50 Mbps/30 Mbps whenever the calculated SNR margin is higher than 9 dB. This gives best system stability and is the default mode.
