FHS2Q01F Optical Light Source 850/1300/1310/1550nm -5dBm Output Power with FC and SC Adapters


SKU: N/A Category:

FHS2Q Series Optical Laser Source is an advanced version of FHS2 Series of Optical Laser Sources, with two more calibrated wavelengths.

Auto-wavelength Recognition:
FHS2Q Series Optical Laser Source transmits with a wavelength-identification digital encrypted protocol, enabling FHP2 Series Optical Power Meter to automatically use the proper calibration wavelength. This feature reduces the need for communication between the two technicians and decreases the possibility of making mistakes.
FHS2Q Series Optical Laser Source offers excellent stability and portability for accurate fiber optic testing.
Two output ports provide stable laser power at four wavelengths. The compact unit operates in either continuous wave (CW) mode or modulated mode. A low battery indicator reminds the user of replacing the battery.
