Interpreting filenames
Each digit in a filename has a specific meaning. For example, consider the number S2300045. The
digits, from left to right, have the following definitions:
Digit Description
1st S indicates single-mode fiber. M indicates multimode
fiber. D indicates diode only.
2nd Indicates the modulation frequency range. 1 means up
to 3 GHz. 2 means up to 6 GHz.
3rd Indicates the wavelength. 3 means 1300 nm. 5 means
1550 nm. 8 means 850 nm.
4th thru 8th These remaining 5 digits are the specific calibration data
number for your source or receiver. This number is not
the same as the instrument’s serial number.
9th thru 10th CR indicates a receiver. CS indicates a source. For DOS
formatted files, these digits form the filename
extension.
