The Datacom Textron Dual Laser Source is a palm-sized instrument supporting
the 1310nm and 1550nm transmission windows. This compact, rugged, and
splash-resistant laser source is used for installing, maintaining, and
conductiong research on singlemode SONET/SDH, cable TV, ATM, and other types of
fiber optic links.
All Datacom Textron laser sourecs feature a high-performance universal
connector interface. The universal connector interfae is complemented by a full
range iof screw-on/screw-off adapters supporting a number of industry-standard
PC (physical contact) connectors, such as ST, SC, and FC types. The universal
connector interface is also easy to clean, ensuring accurate and consistant
measurements.
In addition to the overall advantages of the univesal connector interface,
the output signal performance of the Datacom Textron laser source is also
characterized by two useful features:
1) The absolute output power level is calibrated, emabling efficient
transmission-loss measurements. The user is thus assured that the output power
level is consistant everytime the unit is turned on. Furthermore, the
reproducibility of the output power level is matched by the multi-wavelength
reference storage capabilities of the Datacom Textron optical power meter.
2) The user may select either continuous wave or modulated (pulsed) output.
The modulated output may be selected to match the frequency signatures
(270Hz/1kHz/2kHz) required by fiber identifiers and other types of optical
signal tracers via a switch inside the battery compartment.
The Datacom Textron laser source is powered by two AA-size 1.5 volt alkaline
batteries providing at least 36 hours of operation. A combined wavelength and
battery status LED indicator blinks when the batteries are low. These laser
sources also incorporate an auto-shutoff feature that powers down the instrument
if the buttons on the front panel is not depressed for 15 minutes. This
auto-shutoff feature may be disables via the front panel controls.
