Notes:
1) Ensure sufficient protection against high energy back reflection pulses from solid state lasers. High energy back reflection damages the diode (for example stimulated Brillouin scattering). Typical damage threshold for 8ns puls @200KHz is 0.05µJ (this level is not covered under warranty).
2) Intensity noise of light from modules with PM fiber after polarizer increases with lower polarization extinction ratio (example 6 /10/13 dB can result in intensity noise as high as 50/20/5 %). The intensity noise is sensitive to varying stress (by mechanical and temperature effects) introduced to the PM fiber.
3) Wavelength is measured in air. Without wavelength stabilisation by a fiber bragg grating(FBG) multiple peaks (side modes) around the average wavelength for a specific current in a range of (1-3) nm are observed. The full width have maximum (FWHM) of those peaks can suddenly narrow or broaden. Side mode suppression counts the first side peaks next to the main peak. A peak is defined by significant lower values left and right to this peak.
4) With wavelength stabilisation by a fiber bragg grating (FBG) a single peak for a specific current is observed. The full width half maximum (FWHM) of this single peaks is stable over time as long as it it is not disturbed by further back reflection from the outgoing optical path.
5) Rise and fall times depend on appropriate driver and can be lower than 1ns with the low inductive version.
General Parameters / Accessories
(1) A standard human body model (1.5kOhm, 1000pF) is used for ESD thresholds
Note:
Absolute maximum rating for the laser diode operating current in cw mode may be applied for short period of time only (<10s). Exposure to maximum ratings for extended period of time or exposure above one or more max ratings may cause damage or affect the reliability of the device.
