The TM102N-SM L5819 optical laser source is a tool necessary for attenuation measurements of optical path in networks based on multimode fibres. The source generates laser beams of predetermined wavelengths (850/1300 nm) and power (-7 dBm) to ensure reliable and accurate measurements.

The device generates 850 nm or 1300 nm laser beams at the power level of -7 dBm, as a constant (CW) or modulated wave with the frequency of 270 Hz, 1 kHz, or 2 kHz. Short-term stability of the light source is below 0.04 dB for time spans below 15 minutes. The device can operate in the temperature range of -10°C to +50°C.

The tip is dedicated for SC/PC connectors (2.5 mm ferrules). Thanks to its small size and low weight, the device is ideal for field applications. It is powered by three AAA batteries (not included).

Key features:

• generated wavelength: 850 nm or 1300 nm,
• output power: -7.0 dBm,
• AUTO-OFF function when no activity is detected,
• easy to read, backlit screen,
• small size and low weight,
• simple and intuitive operation.

Ideal temperature and environmental conditions: 1300 nm, CW mode: temperature 23±3°C, RH <70%. The device should be warmed up before use (25 minutes, preferably at 25°C).
