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）.
