LaserLite Model OTOT-870 Standalone or 1RU 19" EIA
Rack-Mount 1310nm Optical Transmitter
Available RF bandwidth of 48-
870MHz supports most analog and
QAM digital broadcast transport
applications.
External RF and optical test points
facilitate optical circuit set-up and
maintenance.
The Olson Technology, Inc. Model OTOT-870 1310nm
48-870MHz CATV Broadcast Transmitter is a cost-effective, high
quality, full-featured standalone or 1RU 19" EIA optical
transmitter. Designed for optical transport of analog and QAM
digital broadcast signals, the transmitter is ideal for CATV
Hybrid Fiber Coax (HFC) applications, as well as direct
transmission of CATV RF signals in Industrial, corporate,
government, educational, and other applications.
LaserLite
The Model OTOT-870 transmitter uses state-of-the-art RF and
optical component technology. A comprehensive lineup of DFB
laser offerings provides superior performance over a wide range
of optical budgets (up to 16dB of loss), allowing unrepeatered
spans of over 45km (28 miles) when used in conjunction with
high performance, high sensitivity node receivers such as the
Olson Technology Model OTPN-1000 or OTMN-II. Less deman-
ding applications can operate to 25dB of loss or 70km (43 miles)
distance.
The rugged, self-contained OTOT-870 provides exterior RF input
and optical output connections, plus front panel RF and laser
test points. The field-configurable SC/APC (or optional FC/APC)
optical output connector can be mounted on the front or rear
panel of the unit. The OTOT-870 is cooled with forced air via an
external high MTBF fan designed to be field-replaceable without
interrupting operation. The stand-alone unit can be rack-
mounted using the Model OTLL-RMKIT-1 to mount up to three
OTOT-870’s in a 1RU (1.75") 19" space.
The Model OTOT-870 is the perfect companion to Olson
Technology’s OTPN-1000 and OTMN-II optical nodes. It is also
designed to operate with optical receivers from most leading
manufacturers. The companion OTOR-300 return receiver
works with all RF return path optical transmitters in the 5MHz to
300MHz frequency range.
