SLD-MS系列-微型SLD光源模块
产品描述：
SLD-MS-series are miniature broadband SM fiber light source
modules at different wavelengths in 670-1630 nm spectral
range for applications requiring reliable, powerful, stable and
low noise SLD light source with a broad and flat spectrum and
a short coherence length.
SLD module inside a light source is powered up by a highprecision
miniature current and temperature controller.
Controller should be supplied by a 15-24 V DC voltage. Low
noise internal DC-DC converter protects SLD and controller
from possible variation and a short-term instabilities of external
DC supply. Controller allows easy control of main SLD
parameters via “ANALOG” I/O connector. Monitoring of overall
status of a light source is easy possible via “LOGIC” I/O
connector. It also provides a number of SLD protection
means, including independent limiting of maximum possible
SLD drive current. SLD current may be changed either by a
built-in potentiometer or by applying analog voltage to
corresponding pin of “ANALOG” I/O. In a standard version,
SLD may be modulated (ON/OFF) up to 50 kHz. Modulation
rate may be extended to 100 kHz upon request. Indicating
LEDs on a top cover of a light source allow easy visual control
of light source status.
Standard models have FC/APC finished, 50 cm long single
mode fiber pigtail. Fiber is protected by 3 mm tube. 900
microns loose tube may be used upon request.
Light source modules must be put onto an appropriate heat
sink for getting a widest possible operating temperature range.
However, it is also possible to use SLD-MS without
heatsinking, although in a limited range of ambient
temperatures. Particularly, highest operating temperature
without external heatsinking is +40 °C for all models and up to
+50 °C for selected models (free air circulation around the
package is required).

* Recommended voltage is 18 V DC.
** Different SLDs with different SLD drive current and heat generation may be used in SLD-MS light source modules. 0.7 A
maximum current of DC power supplied is required to get stable performance over widest possible range of ambient
temperatures when SLD drive current is around 250 mA. Less powerful DC power supplies may be used in case of lower
SLD drive currents. 0.3 A is typically required if SLD drive current does not exceed 150 mA, and 0.5 A is typically required
for SLDs with drive current around 200 mA.
*** Short-term peak current to assure rapid switching-on at temperature extremes. |
