Description
The Proteus Node
Return Digital Transmitter with Ethernet is
a digital, return path transmitter that has the capability of
adding an Ethernet module that can provide point-to-point 10
Mbps and 100 Mbps Ethernet drops. This product must be
used in conjunction with the Laser Link

Return Digital
Receiver with Ethernet.
The base node transmitter module (left half of photo shown)
digitizes two separate signals in a frequency band between 5-
42 MHz. It multiplexes the digital signals together into a serial
digital bit stream then converts the digitized signal to an
optical signal and transmits the optical signal to the receiver.
The Ethernet node receiver module attaches to the base
node transmitter module and provides up to five full duplex
10Base-FL and one 100Base-FX Ethernet drops.
