Berkeley Nucleonics (BNC) is announcing the first optical pulse generator to provide 100mW pulses through a single-mode fibre
High power optical pulse sources with adjustable rates, widths, and power levels speeds the testing of optical receiver and rangefinder systems.
These diode-based, fibre-delivery light sources provide light that is insensitive to vibrations and harsh environments.
To provide comparable light levels in the past, multi-mode fiber was used.
Unlike a multi-mode fibre configuration in which vibration and fibre placement can affect power levels, the model 155H-4 uses a more stable single-mode fibre.
BNC's 155H-4 provides 100mW of peak power at 1550nm.
If requested, wavelengths from 1540nm to 1580nm can be selected by the factory.
The 155H-4 allows external triggering of the light source to follow a user-generated event, or the instrument can self trigger.
Delays (range) may be dialed in 1ns steps making an external delay (range) generator unnecessary.
The 155H-4 can be modulated to create pulses with repeatable and identifiable patterns on the pulse top.
Target identification may be an application.
Since the light source is triggerable and drivable, a pattern of multiple pulses, irregularly-spaced, can be created on the same output.
Multiple target simulation may be an application.
