| Manufacturer's Description |
Tunable laser sources are basic tools for characterizing and testing optical amplifiers and components. The HP 8618D/E/F Tunable Laser Sources operate in the 1550 nm transmission window and cover the wavelength range needed to test dense WDM component designs. All three products are equipped with a built-in side-mode filter to ensure true single-mode operation over the full wavelength range. Output power and wavelength are selectable independent from each other.
Wavelength scans, which require an output power that is stable over time and fault across all wavelengths, can be performed reliably, accurately and quickly. Built-in software allows single or dual channel loss, return loss and coupling ratio measurements together with an HP 8153A Lightwave Multimeter. The instruments' dependability and reliability make them perfect for integration into a fully-automated production test environment. |
