2 Brief description The optical laser source FHS2 is suitable for use as a small, handy laser transmitter that allows attenuation in optical fibres, fibre optic splitters, patch cables etc. to be measured with the aid of an optical level meter at the other end of the line.

TWIN mode. The TWIN function on the FHS2 must also be switched on for this. In this mode, a switchover from 1310 nm to 1550 nm and back on the FHS2 laser source automatically switches over the FHP2 level meter as well, without requiring the user to operate the level meter on site.
2.4 Transmission range using arrow up and down The FHS2 optical level meter has an output level of –5 dBm after being switched on. This can be increased or decreased by 3 dB by setting the required signal strength in 0.1 dB increments using arrow up and down.

2 Brief description The optical power meter FHP2 is used to measure optical levels in the laboratory, in optical LAN and WAN networks, and in HFC and FTTH networks. Optical powers with different wavelengths (850/1300/1310/1490/1550/1625 nm) can be measured at levels ranging from –50 dBm to +26 dBm.

FHS2 laser source by plugging in the laser source on one side and measuring the level with the FHP2 level meter on the other side. TWIN mode is a special mode that allows the FHS2 transmitter to use a log to relay control commands to the FHP2 receiver.
2.4 Reference function (REF button): The REF button allows the value of a level received on a previous occasion to be used as a basis for additional measurements. The additional measurements then use this base value as a reference. The current reference threshold is then set to a relative offset of 0 dB, which appears on the display after the button is pressed.
The FHP2 optical level meter has a measuring range from –50 dBm – +26 dBm at 1550 nm. The FHS2 transmitter (max. output level –2 dBm) and the reception range of min. – 50 dBm on the optical power meter can be used to measure an attenuation budget of max.

2 Brief description The visual red light source is used to screen optical fibres when troubleshooting and for fibre classification. The red light source allows individual optical fibres to be localised in bundles of fibres. Any light escaping from the fibre sheath due to crushing, broken fibres or at splices, and other occurrences, can be identified visually.
Page 26
The 2 × AAA batteries inserted in the battery compartment on the rear supply the red light source with the energy required for approx. 5–6 hours in CW (constant mode). The operating time is significantly longer in pulse mode. After use or once the measurement is complete, ensure that the dust cap is put back onto the output to prevent contamination of the device.

2 Brief description The optical fibre microscope allows the connector surface of SC, SC or ST fibre optic connectors to be appraised. The layout of the internal optical lenses allows 400× magnification. Optical fibres with ferrules with a 2.5 mm diameter (SC, FC or ST) can be connected Both APC (8°) or UPC and PC (0°) connectors can be inserted If the optical fibre has been inserted into the front of the optical fibre microscope, then the end of the fibre can be focussed using the wheel.
