Description
The Laser Link
Return Digital Receiver with Ethernet is a digital,
return path receiver 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
Proteus
module that can provide point-to-point 10 Mbps and 100 Mbps
Ethernet drops. This product must be used in conjunction with the
Proteus
Node Return Digital Transmitter with Ethernet.
The base shelf receiver module (left half of photo shown) converts an
optical signal to a digitized, electrical signal. It de-multiplexes the
serial bit stream and then converts the digital signal back to the two
original 5-42 MHz RF signals. The Ethernet shelf transmitter module
attaches to the base module and provides up to five full duplex
10Base-TL and one 100Base-TX Ethernet drops.
