Γέφυρα δικτύου PLANET VC-234G

The PLANET VC-234G is a Gigabit Ethernet-over-VDSL2 network bridge that enables high-speed data transmission over existing telephone copper wires. It combines VDSL2 and Gigabit Ethernet technologies to extend Ethernet networks without rewiring, offering symmetric rates up to 190/190 Mbps over short copper loops and long-reach connectivity up to 1.4 km at reduced speeds. The device includes four RJ45 Ethernet ports, two RJ11 phone jacks (one for VDSL and one for POTS) and supports vectoring to reduce crosstalk when used with vectoring-enabled DSLAMs.

Advantages

The VC-234G provides high throughput on existing telephone lines using VDSL2, supports Gigabit Ethernet LAN speeds (10/100/1000 Mbps) and includes a built-in POTS splitter so voice service can share the same copper pair. Its support for ITU-T G.993.5 vectoring improves maximum line bandwidth by removing crosstalk, and the unit offers simple installation with Plug-and-Play operation, front-panel status LEDs and selectable CPE/CO modes via a DIP switch.

Suitable for

• Extending Ethernet over existing telephone copper wiring
• Delivering bandwidth for ISP triple-play services (IPTV, VoD, VoIP)
• Providing long-reach Ethernet links where fiber or rewiring is not available
• Point-to-point connections between central office and customer premises (use CO + CPE pair)

Key specifications

• Data rates: VDSL2 symmetric up to 190/190 Mbps (G.INP, Sym, 8 dB) at ~300 m; asymmetric up to 240/120 Mbps (G.INP, Asym, 8 dB); long reach up to 20/12 Mbps at ~1.4 km
• Ethernet: 4 × RJ45 ports, 10/100/1000 Mbps, IEEE 802.3/802.3u/802.3ab, 802.1p, 802.3x
• Telephone interfaces: 2 × RJ11 (1 × VDSL, 1 × POTS) with built-in POTS splitter
• Vectoring: ITU-T G.993.5 support (works with vectoring-enabled DSLAMs)
• Mode selection: CPE or CO via DIP switch
• Power: 5 V DC, 2 A
• Material/color: Metal housing, blue
• Weight: 0.35 kg

How to use

Install the VC-234G by plugging the unit into the existing RJ11 telephone jack for VDSL connection and connect Ethernet devices to the RJ45 ports. If POTS telephone service is required on the same line, use the device’s POTS RJ11 jack; the built-in splitter separates voice and data. For a point-to-point link, set one unit to CO mode and the other to CPE mode using the DIP switch. Verify link and activity using the front-panel status LEDs. The device operates as a plug-and-play converter and is compatible with standard network protocols.

Recommendations

Use the VC-234G with vectoring-capable DSLAMs to maximize line bandwidth and place the CO and CPE units at the correct ends of the copper pair. For optimal throughput, minimize loop length and avoid noisy or damaged copper wiring; check LEDs for diagnostics and follow local regulations for network installation.
