VX-VEB160G1 Lite Industrial Gigabit Ethernet Copper Extender

$115.00

Versa Technology’s VX-VEB160G1 is a Lite Industrial Grade Ultra-Speed Gigabit Ethernet Copper Extender that supports a remarkable aggregated bandwidth up to 300Mbps (Downstream: 150 Mbps/Upstream: 150 Mbps). It delivers fiber-optic like speeds on existing copper infrastructures, enabling a good alternative where fiber is not economical to deploy. The VX-VEB160G1 is equipped with a Gigabit Ethernet port (RJ-45 connector) and one VDSL2 port (RJ-45 connector) in a metal enclosure for easy installation in extended temperature environments.

There are 8 different profile settings that can be flexibly selected via the DIP switches to suit various applications and environments. The Symmetric profile can be applied as a standard Ethernet connection with equal upload and download speeds. The Asymmetric profile can be used for other services like video streaming or IP surveillance services, which requires high traffic flow in a unidirectional configuration with different upload and download speeds. The VX-VEB160G1 supports transparent LAN bridging to extend Ethernet service over UTP, Cat 5+ or Coaxial cables. With superior performance, the VX-VEB160G1 is the best high throughput Long Reach Ethernet Extender for service providers. It can deploy IP-based networking services and meet various application scenarios in harsh environments.

VX-160CE VDSL2 SFP Modem (Remote Telco Grade)

$119.00

Versa Technology’s VX-160CE is a Telco Grade VDSL2 SFP modem that interconnects with Gateway Processor by using a MSA (MultiSource Agreement) compliant hot pluggable electrical interface. The chipset inside the VDSL2 SFP modem supports all VDSL2 profiles that are defined by ITU-T G.993.2, G.994.1, G.997.1 and among other standards, ensures its interoperability with all existing broadband network services. Furthermore, Versa’s VX-160CE also features the latest ITU standards such as G.inp (G.998.4) and G.vector (G.993.5).

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 the VX-160CE VDSL2 SFP in Service Providers’ product portfolio will help them significantly reduce the software porting and testing effort and shorten their product time-to-market.

Versa’s VX-160CE 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 need for Service Providers to maintain more than one type of CPE device in the field or in the warehouse, moreover, this also can give them the possibility to future upgrade. Users can upgrade to any broadband access data rate easily only by plugging in different types of WAN SFPs such as VDSL2 35b/G.fast or optical TRx SFPs with the same internet box and user interface.

  • Supports all VDSL2 standards defined in ITU –T G.993.2, G.994.1, G.997.1
  • MSA compliant hot pluggable electrical interface
  • Supports G.inp (G.998.4) and G.vector (G.993.5)
