1 GHz, then the frequency grid would be as shown in the below image. The general rule for the set of valid frequency GRID points is: 36 / 80 Quantifi Photonics | IQRX EPIQ User Manual | Version 2.00... -
Page 37: Frequency Tuning
In the example below, the user sets the output frequency to 193.414489 THz, with a GRID spacing of 1 GHz. The laser first tunes to the closest GRID point below the intended frequency value (193.414 THz), and then uses FINE TUNE OFFSET to fine tune by 489 MHz up to the final set point. 37 / 80 Quantifi Photonics | IQRX EPIQ User Manual | Version 2.00... -
Page 38: Frequency Fine Tuning
In the example below, the GRID spacing has been set to 20 GHz, meaning that between any two adjacent GRID points, there lies an 8 GHz region that is non-accessible. If tunability is a primary concern, it is suggested that the user set the GRID spacing to be <= 6 GHz. 38 / 80 Quantifi Photonics | IQRX EPIQ User Manual | Version 2.00... - Page 39 39 / 80 Quantifi Photonics | IQRX EPIQ User Manual | Version 2.00...

Page 73: Working With Optical Fibers
Always inspect fiber end faces for cleanliness using a fiber inspection probe before inserting them into a port.. If required, clean fibers and faces as detailed below. Quantifi Photonics is not responsible for damage or errors caused by bad fiber cleaning or handling. NOTE To avoid damaging ferrules or fiber faces due to mismatched connectors, always check ports and connector type information before inserting a connector. - Page 74 If your connector features a screw sleeve, tighten the connector to firmly maintain the fiber in place. Do not over-tighten, as this will dam- age the fiber and the port bulkhead. NOTE Failing to align and/or connect fiber-optic cables properly will result in significant signal loss and reflection. 74 / 80 Quantifi Photonics | IQRX EPIQ User Manual | Version 2.00...
