 The LTS-1500 is a small, rugged automated fiber optic loss test set that characterises singlemode fiber links at wavelengths of 850, 1300, 1310, 1490, 1550 and 1625 nm.

 It is comprised of a sensitive InGaAs based optical power meter calibrated at six wavelengths with better than -75 dBm noise level plus a stabilised laser light source with up to three selectable wavelengths.

 In the Autotest mode, the master unit changes wavelengths at a fixed rate and informs the slave unit of the wavelength currently being measured. Storing the loss measurement saves the loss at each wavelength in memory. Up to 2000 triple wavelength measurements may be stored and recalled via the unit's USB port or from the front panel. PC application software is provided for downloading stored data and organising the information.

 The units also performs fiber identification functions with modulation frequencies of 270, 1000 and 2000 Hz.

 Power is obtained from a rechargeable lithium polymer battery that provides more than 15 hours of continuous operation, it's universal power supply, or in a pinch, any common 9 V alkaline battery.

 Standard accessories include a protective rubber boot and stand, USB cable, adaptors for FC, ST or SC connectors, universal power supply/charger, CD containing application software and an operating instruction booklet.

 Options include a reduction in the number of laser wavelengths supplied.
