Search Tips...

Keyword Search
Our search engine uses any or all keywords typed in the text box to give you product search results.
For instance, typing in kvm will give you a broader set of results than kvm switch cables.

Note, however, that keywords in quotes are treated as a single phrase and will not be evaluated individually.

Booleans (AND, +, OR, NOT, -) are not supported.

Also, some keywords will not return results, and may automatically correct to a similar keyword.

Part Number Search Selection
Select this Search in the drop down box to search by part number instead of keywords.

Wild Card Search
The * character is only supported in a limited capacity. Using whole words is the best approach whenever possible.

"New Search" Radio Button
Search the entire section that you are currently in.

"Search Within Results" Radio Button
Enter keywords or a part number to limit your results within the previously searched results.


Other features

A list of all matching product categories or resources will appear in the upper left corner of the results page, when applicable, to help you further narrow your results, if you desire.

Use the "sort by" drop-down menu on the results page to sort by "most popular" and price (low to high or high to low)
in the store section.

    • Description

    10BASE-T/100BASE-TX Hardened Ethernet Extender over vDSL, 4-Port


    Quick Facts

  • Extends 10- or 100-Mbps Ethernet up to 1.2 miles (2 km).
  • For use at extreme temperatures from -40 to +167° F (-40 to +75° C).
  • Adds four ports at the edge of your network.

    • Further Details

  • Simple plug-and-play installation.
  • Saves wiring costs by using voice-grade copper wire—even phone wire you already have installed.
  • Uses symmetrical vDSL for speeds of up to 30 Mbps.
  • Transparent to network protocols.
  • Eight speeds with easy-to-read speed indicator LEDs on top of the extender.
  • Auto MDI/MDI-X on the Ethernet ports.
  • Autosensing for Ethernet speed and duplex.

  • Hot swap extender without powering down.
  • A switch configures the extender for local (CO) or remote (CP) use.

    This 10BASE-T/100BASE-TX Hardened Ethernet Extender uses vDSL to provide an easy, inexpensive way to extend the reach of your Ethernet network over ordinary voice-grade copper wire. Use the Hardened Extender for harsh environments and extended temperature ranges. Because you use your existing copper infrastructure, you save on cabling costs. Plus it has an internal switch and four Ethernet ports, so you can use it to easily add remote ports at the edge of your network.

    Easy setup
    Just plug a hardened extender into each end of your copper wire and use simple DIP switches to set one unit as local (CO) and the other as remote (CP).

    The extender is transparent to upper level protocols such as TCP/IP, and there's never any software to install. Plus, the RJ-45 port autosenses speed and duplex, and it features MDI/MDI-X, so your Ethernet is virturally foolproof!

    Standalone or rackmount
    You can use this compact extender as a desktop or a wallmount standalone unit.

    NOTE: Must be used in pairs with another LB304A, with the 1-port version of this extender (LB303A), or with the LinkGain Ethernet Extender over VDSL (LB300A-R3).
