Description
Hughes LAN Systems ProBridge 8033 Ethernet to Ethernet Bridge A004852-02
The Hughes LAN Systems ProBridge 8033 is a standalone Ethernet-to-Ethernet network bridge designed to interconnect two separate Ethernet LAN segments. It operates on two channels (ch 0 and ch 1) and uses AUI (DIX) connectors for both Ethernet ports, with an additional AUX port for management or secondary connectivity. The unit is powered via an external DC supply and carries UL and CSA certifications. It was made in the USA.

Applications
The ProBridge 8033 is a product of Hughes LAN Systems, a networking division active in the late 1980s and early 1990s when Ethernet bridging was a standard approach to extending LAN infrastructure. Ethernet bridges like the ProBridge 8033 were used to connect two physically separate Ethernet segments, filtering and forwarding frames based on MAC addresses to reduce collision domains and extend effective network reach. This was a common solution in campus, office, and industrial networks before Layer 3 routing became the dominant architecture. The AUI (DIX) interface was the standard Ethernet attachment point of that era, connecting to transceivers for 10BASE-T, 10BASE-2 (coax), or 10BASE-5 (thick Ethernet) media. Today, units like this are sought by organizations maintaining legacy network infrastructure, for use in museum or educational computing environments, or by collectors of early LAN networking hardware.
This Hughes LAN Systems ProBridge 8033 Ethernet-to-Ethernet bridge has been inspected and appears to be in good used condition. The enclosure shows light surface wear and discoloration consistent with age, as seen in the photos. The rear connectors — including both AUI Ethernet ports, the AUX DB-15 port, and the DC power connector — appear intact and undamaged. This unit was pulled from a working environment. No power supply or cables are included. Please view our photo set and contact us if you have any questions.
