Application
The LT1230 is typically used to transmit dial-up
information from a remote Codec to a CSU/DSU at
the demarcation point over single mode or multimode
fiber optic cable. In addition to distance flexibility,
it provides immunity from EMI/RFI interference,
ground loops and lightning strikes.
Description
Intended for Video Conferencing applications,
the LT1230 Fiber Optic Modem transmits RS-366
dial-up information between Codecs and CSU/DSUs,
Hubs and other Network Devices at the demarcation
point.
The LT1230 supports asynchronous data rates up
to 56Kbps and plugs directly into the RS-366 interface
on the Codec and Network Device. It supports all
11 standard RS-366 control signals (typically
5 in, 6 out), including handshaking.
Typical campus network distances are approximately
5 km multimode and 20 km single mode. Distances
can vary depending on the size and type of fiber
optic cable, number of connections and type of
connectivity devices.
The LT1230 works over all popular sizes and types
of multimode (850/1300nm) or single mode (1300/1550nm)
fiber optic cable. Fiber optic connectors are
ST or FC. Electrical connectors are DB25 female.
Diagnostics include an "Active" LED
to indicate that the modem is operating correctly.
Power is 12VDC or 115/230VAC with an external
power cube. An extreme temperature version (-20°
to 70°C), Model LT1230T, is also available.
