The FT-LS20 is a basic single port, dual laser Optical Light Source for use in performing insertion loss measurements and fibre identification tasks on singlemode optical networks. The FT-LS20 features 1310 nm and 1550 nm laser outputs from a single output port. Each wavelength may be transmitted at CW or with a 270, 330, 1000 or 2000 Hz tone. The output port of the FT-LS20 features a removable FC adapter.

Optional SC and ST adapters are also available.

The FT-LS20 is designed for ease of use. It features a large, easy-to-read LCD, which shows the output wavelength and any selected tone. The FT-LS20 also displays the remaining battery capacity and the status of the automatic power-off function. A user selectable backlight enables the FT-LS20 to be used in dimly-lit spaces. The FT-LS20 will operate for approximately 30 hours from a pair of ordinary AA alkaline batteries. An automatic power-down circuit optimizes battery life by shutting off after 5 minutes of operation.

When paired with a Optical Power Meter (such as the FiberTech FT-PM3), the FT-LS20 provides installers, technicians, and field engineers with an accurate, stable source of 1310 nm and 1550 nm optical signal for insertion loss measurements. When paired with a Optical Fiber Identifier (such as the OFI-200, OFI-400, or OFI-400HP), the FT-LS20 provides users with a source of continuous and tone modulated signals that enables individual fibres to be definitively identified. The FT-LS20 is fully N.I.S.T. traceable and complies with CE and RoHS requirements.
