What it is

The JDSU OLS-55 is available with one, two, three, or four wavelengths depending on the model. For singlemode fiber the available wavelengths are 1310 nm, 1490 nm, 1550 nm, and 1625 nm. For multimode fiber (50/125 µm) the wavelengths are 850 nm and 1300 nm.^[1]

How it works

General reference — not yet source-verified

Portable optical sources generate a stable optical signal at one or more calibrated wavelengths using a laser diode or LED. The output is typically continuous wave or modulated at known frequencies to enable synchronous detection by a corresponding power meter.
