Also known as “insertion loss” or “fiber sweep” testing, dB loss testing allows the technician to validate

that all fiber pairs are in working condition. Saving of dB loss test results may be required for closeout

packages. This section explains the necessary steps for testing fiber.

dB Loss Testing

4

4a - Connect Test Jumpers for Referencing

The equipment must be referenced before testing begins. Plug the AC 523 into the DLS 355

and VIS 300C OPM port. Connect the paired LC end of the AC 523 jumper into the AC 4500

loopback as shown below. Turn the DLS 355 on and choose an appropriate wavelength. For SM

fiber testing, 1310 and 1550 wavelengths are most common. Consult your build documentation

to determine which wavelength to use. This guide will show the use of the 1550 wavelength.
