SLS-1XX Stabilized Light Source
激光器模块和系统
圣德科(上海)光通信有限公司
光纤类型: 9/125 光纤类型: 9/125 光纤类型: 50/125, 62.5/125 or 105/125
The SLS-1XX series of fixed light sources is a highly configurable benchtop system offering many different options for light sources. Three versions are available: the SLS-100, a fixed bank of up to 24 discrete LED or laser sources that can be mixed and matched with different source types, wavelengths, or fiber types in one box; the SLS-110, a switched optical source with internal sources that can be combined and switched at the output, enabling combined wavelengths (e.g., 24 channels with 1310/1490/1550/1625 nm) out of many ports; and the SLS-120, a fixed bank of light sources dedicated to CWDM DFB laser sources covering all ITU-T G.694.2 channels from 1270 to 1610 nm (20 nm spacing) with standard 1 mW DFB sources, or optional 10 mW/20 mW DFB lasers with at least 30 dB side mode suppression ratio. Each system comes in either a half-rack or full-rack 2U enclosure, supports common connector types (SC, LC, FC, ST, etc.), and offers USB and Ethernet communication interfaces for automation integration. Thanks to excellent power and wavelength stability, no calibration is required unless specified by quality processes.
