Optical Fibre wavelength Bands-O,E,S,C,L,U-Band
Following wavelength bands are used in fibre optical communication. This bands are used by optical engineers so often.The values in the table are approximate. They have not been finalized as standard values.
|Optical fibre wavelength band||Band descriptor||Wavelength Range (nm)|
|O-band||Original||1260 to 1360|
|E-band||Extended||1360 to 1460|
|S-band||Short||1460 to 1530|
|C-band||Conventional||1530 to 1565|
|L-band||Long||1565 to 1625|
|U-band||Ultra-long||1625 to 1675|
