Using the patchcords also keeps service costs down, as the adaptor
patchcord can be exchanged easily.
Angled contact connectors have up to 30dB higher return loss than
straight connectors, and we recommend them for best performance
results. With angled fiber endfaces, reflected light tends to reflect into the
cladding, reducing the amount of light that reflects back to the source.
Enabling and disabling the laser output
After the Optical Modulation Analyzer application running on the digital
signal analyzer has initialized it, the green LED above the laser output
indicates whether the laser is emitting radiation.
The laser is enabled and disabled by the software.
If the Laser output is on, the green LED on the front panel of the module is
lit. If the Laser output is off, the green LED on the front panel of the
module is not lit.
CAUTION
Before you connect any fiber-optic cable to the Optical Modulation Analyzer,
please ensure it has been properly cleaned.
Fiber-optic connectors are easily damaged when connected to dirty or damaged
cables and accessories. When you use improper cleaning and handling
techniques, you risk expensive instrument repairs, damaged cables, and
compromised measurements.
