3Com NJ100 Network Jack - 3CNJ100

Quadruple LAN Connectivity at the Wall!

The 3Com® NJ100 Network Jack instantly expands a single Ethernet or Fast Ethernet LAN connection into four 10/100 switched ports at any desktop. Up to two optional pass-through ports accommodate dedicated subnets or analog voice lines. The jack’s compact design lets you install it virtually anywhere you need more LAN connectivity without expensive rewiring or a tangle of cables. Replace an existing wall jack, or use it as the LAN outlet in modular office paneling.

IT administrators will appreciate how effortlessly they can extend the existing LAN infrastructure—for a savings of up to 60 percent of the cost of pulling wires. Or they can use VoIP-compatible 3Com network jacks to add networked telephony to user workspaces. Users will enjoy the convenience of having multiple connections for linking mobile and desktop computing devices.
