VC-231GF 1-Port 1000BASE-X SFP + 1-Port RJ11 VDSL2 Converter

New VC-231GF 1-Port 1000BASE-X SFP + 1-Port RJ11 VDSL2 Converter

The Planet VC-231GF is a Long Reach Ethernet solution Single-port Gigabit Ethernet-over-VDSL2 Converter for connecting ultra-fast FTTx deployment with the existing in-building and in-house telephone wire installation.

An Innovative Last Mile Solution Integrated with FTTx and VDSL2

The Planet VC-231GF features one 1000BASE-X SFP slot for remote optical fibre Ethernet connection and one RJ11 port with the VDSL2 technology to provide an excellent bandwidth of up to a total duplex data rate of 300Mbps and can extend a maximum distance of up to 1.4km (4,593ft) over existing telephone wire to the in-house VDSL2 router or bridge, which overcomes in-house fibre installation problems.

The VC-231GF allows ISPs (internet service providers) and System Integrators to deploy Gigabit Ethernet optical fibre cables in the front of the building or subscriber’s house and provide high-speed triple play services over existing telephone wire. They can simply upgrade their current networks without any difficulty. The VC-231GF's compact-sized metal housing makes the installation in a telecom box convenient.

Fibre-Optic Link Capability Enables Extension of FTTx Deployment

With the built-in 1000BASE-X SFP (Mini-GBIC) fibre interface, the Planet VC-231GF supports different optic types for network extension and the distance can be up to 120 km through the fiber connection. Thus, building a network solution of FTTH (Fibre to the Home), FTTC (Fibre to the Curb) for ISPs or FTTB (Fibre to the Building) becomes so easy when long-distance deployment is employed.

VDSL2 Delivering High-demanding Service Connectivity for ISP/Triple Play Devices 

The VC-231G provides an excellent bandwidth demand for triple play devices for home entertainment and communication. Via the latest VDSL2 (Very-high-data-rate Digital Subscriber Line 2) technology, the VC-231GF offers selectable asymmetric/symmetric data rate capability. It works well with a pervasive telephone line network with a symmetric data rate of up to 150/150Mbps (G.INP, Sym, 8dB) over a distance of 300m and 25/15Mbps over a long distance of 1km. The VC-231GF enables many multi-media services to work on the local Internet, such as VoD (video on demand), voice over IP, video phone, IPTV, Internet caching server, distance education, and so on.

Versatile, Flexible and Easy Installation 

The Planet VC-231GF Ethernet-over-VDSL2 converter come with a Plug and Play design. The VC-231GF offers two operation modes, CPE for client side and CO for central side. The CPE or CO mode can be adjusted by using a built-in DIP switch.

For point-to-point connection, the VC-231GF’s CO mode and the VC-231G’s, VC-234G’s or VDR-301N’s CPE mode must be set up as one pair of converters to perform the connection. It gives administrators the ability to reply a fresh local Intranet in various locations by utilizing the original network structure without additional costs.

Implementing with Existing Telephone System

Use the additional splitter from the package of the VC-231GF to share the existing phone line with POTS, thus replacing the existing copper wiring is not necessary. Just plug the VC-231GF with the additional splitter into the existing RJ11 telephone jack and a high-performance VDSL2 network can be connected. It is ideal for use as an Ethernet extender to an existing Ethernet network.

* Performace is based on the VC-231GF (CO mode) that Operates with PLANET VC-231G (CPE mode). The actual data rate will vary on the quality of the copper wire and environmental factors.

Distance Extension with High-Performance FTTx Network Communications

A set of the VC-231GF and VC-231G (VDSL2 Converter) or VDR-301N (VDSL2 Router) could be used to link fiber network and home network that are located in a different place. Through the normal telephone line, it could be set up a 150/150Mbps (G.INP, Sym, 8dB) symmetric backbone, but one VC-231GF must be Master (CO mode) and the remote VDSL2 converter or VDSL2 Router is Slave (CPE mode).
