Specified without connector, If with connector, IL will increase 0.2dB.
Optical Path
| Single Fiber Bidirectional Transmission The wavelength of TX and RX is Different | Dual Fiber Bidirectional Transmission The wavelength of TX and RX can be Same or Different |
CWDM systems can transport 18 wavelengths (1270~1610nm) with a channel spacing of 20nm. In custom application typically use 1470 to 1610nm in the spectrum grid. Compare with DWDM, CWDM has a wider channel spacing than DWDM.
