ALL4781-VDSL2-SFP is a VDSL2 SFP modem that interconnects with Gateway Processor by using a MSA (MultiSource Agreement)
compliant hot pluggable electrical interface. The DSL chipset inside the VDSL2 SFP modem supports all VDSL2 pro les that de ned
by ITU-T G.993.2. Compliancy with G.994.1 and G.997.1 standards, ensures its interoperability with all existing broadband network
services. Furthermore, ALL4781-VDSL2-SFP also features the latest ITU standards such as G.inp (G.998.4)
As broadband access technology has evolved rapidly, Service Providers need to upgrade their broadband network service every few
years. Traditionally, Service Providers have replaced the entire CPE device in order to provide subscribers with faster Internet services.
Not only does it increase their CAPEX and OPEX but also wastes resources and increase inventories. Leveraging ALL4781-VDSL2-SFP
VDSL2 SFP series in Service Providers’ product portfolio will help them signi cantly reduced the software porting and testing effort and
shorten their product time-to-market.
ALL4781-VDSL2-SFP modem realizes the modulation of VDSL2 broadband access. It can be integrated with routers, switches or
residential gateways that are equipped with a SFP type of WAN interface. There’s no more need for Service Providers to maintain more
than one type of CPE device in the eld or in the warehouse, moreover, this also can give them the possibility to future upgrade.
In addition to Allnet ALL4781-VDSL2-SFP, Liyuan Tech supply a wide range of other Intel transceivers. If you have any need or interest, please feel free to send inquiry to global@chn-liyuan.com
