Optical laser source GRANDWAY FHS1D02 L5825 is the tool necessary for measuring optical power loss in fiber-optic networks (FTTx). The source generates laser beams of predetermined wavelengths and power for precise measurements.
The device generates laser bream of the wavelength 1310 nm or 1550 nm at the power level of -5 dBm, as constant wave (CW) or modulated with 270 Hz, 1 kHz, or 2 kHz frequency. A short-term stability of the light source is better than 0.1 dB for a time shorter than 15 minutes, and a long-term stability (above 5 hours) is better than 0.2 dB. The device can operate in the temperature range of -10°C to +50°C.
Due to small size and low weight the device is ideal for field applications. The tip is dedicated for FC/PC connectors with 2.5 mm ferrules. The device is powered by four AAA batteries.
The device is dedicated for use together with optical power meter GRANDWAY FHP1B02 L5821.
Proper positioning of the FC/PC plug.
The guide of the plug fits into the groove on the socket.
