Single Tests

The SINGLE TEST mode on the DSP-4000 rotary switch lets you run
individual fiber tests. Single Tests are useful for quick checks of continuity,
length, or loss, and for isolating faults and testing repairs. Single Tests run
continuously, so you can make adjustments to a link and watch the results as
they happen.

Single Tests for Smart Remote Mode

If an Autotest fails, you can use these tests to isolate problems on one of the
fibers in a link. To connect for a Single Test in Smart Remote Mode, refer to
Figure 8.
•
Loss (Output Fiber or Input Fiber): Measures optical
power loss on the fiber connected to the main unit's output or input port.
•
Length: Measures fiber length, as done during an Autotest.
•
Propagation Delay: Determines the propagation delay of each
fiber.
•
Near End Power or Far End Power: Measures the optical
power received by the main unit (near end) or the remote unit (far end).
•
Send (850 nm, 1300 nm, 1310 nm, 1550 nm,
VCSEL 850 nm,or FP 1300 nm ): The possible wavelengths
displayed depend on the type of Fiber Test Adapter installed. The FTA-
420 allows 850 nm or 1300 nm (multimode). The FTA-430 allows 1310
nm or 1550 nm singlemode. The FTA-440 allows VCSEL 850 nm or FP
1300 nm laser. The main unit continuously transmits light of the selected
wavelength from its output port.
