Hi Deepak, Most modern DWDM transponders with 160km network side optics will be launching anywhere from -2dBm to +2dBm depending on how warm the laser is, assuming a +2 dBm launch you are looking at around 1.6mW -
It might be good to note that there are ZX GBICs (120km variants) that are launching at +2 to +5, so you don't really need a DWDM system to achieve these levels. Care not to expose eyes to this light should be taken whenever handling optics of any kind.
