THE Model 373 LAN transceiver, available from Boston Technology , breaks the distance barrier of Ethernet-based Local Area Networks and achieve total system safety from electrical interference and surges.

The addition of a pair of Model 373's allows a LAN to be extended to a distance of 2km, (more than a mile). Thus LANs can be spread to other buildings and facilities.

When this is attempted with coax wires and repeaters there is usually concern with electrical interference from other equipment, ground loops, surges and lightning which may strike in the vicinity of the cable link.

These potential problems all disappear with the Model 373 LAN-Spreader since the connection between the server and workstations is fibre optic cable which is impervious to all of these disturbances.

The full duplex signals of the 10Base-T port are converted to optical signals and driven over fibre cables. The Model 373 is powered from an ac adapter.

A group of five LEDs provide indication of fibre optic link monitor, twisted-pair link monitor, collision, traffic and power. An SQE switch ensures compatibility with both old and new Ethernet adapters by allowing the user to enable or disable the SQE Heartbeat option.
