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）.
