OLTS 5 Optical Loss Test Set
The OLTS 5 Optical Loss Test Set series offers end-to-end single-mode testing at either
1310/1550 nm or 1550/1625 nm. The OLTS 5 may be operated in automatic or manual
test modes. In its “two-unit” automatic test mode, a pair of OLTS 5 test sets may be used
to measure the end-to-end, bi-directional insertion loss of a pair of single-mode fibers at
1310/1550 nm or 1550/1625 nm. Tests are started and controlled by the user from the
OLTS 5 configured as the Main unit. Test progress messages and results are displayed on
the Remote unit. Full test results can be reviewed and saved in the Main unit. Thresholds
may be set to provide Pass/Fail results. In its “single-unit” automatic test mode the OLTS 5
can measure bi-directional, dual-wavelength insertion loss of patch cords, or fiber optic
cables while they are still on the reel. In the manual operating mode individual OLTS 5 test
sets can operate either as an optical power meter (OPM) or dual-wavelength laser source.
The OLTS 5 can store dual-wavelength, bi-directional insertion loss results for up to 1,000
fibers. Test results can be organized in up to 20 user-named files. Results are transferred
to a PC using the supplied serial cable or RS232 / USB adapter. Windows® compatible
software is provided to view, edit, and print test results. OLTS 5 units are sold individually
but normally used in pairs.
