VDSL2LAN Extender 100 Series
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. Proscend 100 VDSL2 LAN Extender 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, costeffective form factor offers Systems Integrators, small business owners an attractive Long Reach Ethernet solution.
* 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
* 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.
