Introducing the HP Fiber-Optic Hub Plus

The HP 28682A Fiber-Optic Hub Plus is a 10-Mbit/s multiport repeaters and is designed to be

compatible with the IEEE 802.3 Fiber-Optic Inter-Repeater Link (FOIRL) standard. It can

form a fiber-optic star backbone with HP EtherTwist or other Type 10Base-T subnetworks, or

in combination with thin or thick coaxial cable networks. Or, it can directly connect PCs and

computers that have a fiber-optic adapter card or a fiber-optic transceiver attached. See the HP

EtherTwist Technical Reference Guide (p/n 5091-3237E) for network configuration guidelines.

Features

The HP Fiber-Optic Hub Plus has the following features:

The following ports:

– Eight fiber-optic ports, each consisting of a transmit and receive pair of ST

connectors for 62.5/125 µm or 50/125 µm fiber-optic cable.

– A ThinLAN port for connection to thin LAN coaxial cable.

– An AUI port for connection to an external transceiver. This additional port can be

used with the appropriate transceiver to connect any media, such as twisted-pair,

thick or thin coaxial, and fiber-optic cable. It can be used at the same time the other

ports are being used.

Note that all the network ports (fiber-optic, ThinLAN, and AUI) are active and can

be used at the same time.

– An RS-232-C console port for attaching a terminal or terminal emulator that can be

used to customize the hub’s configuration, monitor hub activity and status, and run

tests of the hub. Console access can be either local, by direct attachment to the

console port, or remote, through a modem connection.
