OLTS 5 - Broadband Loss
The OLTS 5 Optical Loss Test Set series offers end-to-end single-mode testing at either 1310/1550 nm (OLTS 5-3 model) or 1550/1625 nm (OLTS 5-5 model).

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 1310/1550nm 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.

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.

OLTS 5 units are sold individually but normally used in pairs.
