Optical delay solutions overview / Optical delays
Use fixed and variable time delay solutions alone or in series to manage your delay from wavelength range to tens of microseconds
Optical delay solutions overview summary
IDIL Fibres Optiques is recognized as a leading manufacturer of optical systems for delay management. Our solutions offer best optical and delay resolutions. They can be customized to meet your requirements : delay range, stretch range, length, connector, fiber type, integration (in rack, spool), mode switching or multiplexing…). Moreover, you can combine different systems into one rack.
