Wideband operation - 1520nm to 1620nm for C+L bands, 1460nm to 1620nm for S+C+L bandsĪ: ID of the Operating Wavelength Range of the isolator, a=CL for C+L bands a=SCL for S+C+L bands.ī: Isolator Stage b=S for single stage isolator b=D for dual stage isolator.Ĭ: Pigtail Type, c=0 for 250 micron bare fiber c=1 for 900 micron loose tube pigtail, etc.ĭ: Connector Type, d=FA for FC/APC, d=SU for SC/UPC, d=N for no connectors, etc. COMMFRONT Industrial USB Isolator, USB 2.0, 5000V Optical Isolation, Low and Full Speed Data Rate: 1.5Mbps and 12Mbps, Plug-n-Play, No Drivers Required. This optical isolator for high power lasers uses glass that has the highest magneto-optical performance in the industry.However, the device structures and characteristics are variable, which are detailed as follow. The basic and common principle for optical isolators is Faraday effect. Optical isolators that covers the whole S, C and L bands (from 1460nm to 1620nm) are also available. This troubling feedback can be eliminated by the application of an integrated optical isolator put between the transmitter diode and the connecting fiber. Optical isolators are widely used in optical fiber communication systems, optical fiber sensing systems and fiber lasers.
The key specifications of an optical isolator are the insertion loss, the return loss, and the reverse isolation of the device. This optical isolator can also be used in optical amplifiers to achieve wide-band amplification. Ascentta manufactures a wide range of isolators, including single mode, multimode, and polarization maintaining (PM) isolators. An optical isolator is a nonreciprocal device that transmits an optical wave in one direction but blocks it in the reverse direction much as the function of a diode in an electric circuit. A truly wideband isolator can be the key component to ensure the high performance transmission of WDM signals in the whole C and L bands. provides uniquely designed wide-band optical isolators that cover the whole C and L bands (1520nm to 1620nm) continuously.
