			5.2.5. ITU-G.695 Application Code Mapping
			Recommendation [ITU-G.695] defines the Application Codes: CnWx-ytz
			and B-CnWx-ytz and S-CnWx-ytz.
			Where the optional prefixed are:
			B: Bidirectional
			S: a system using a black link approach
			And the rest of the application code is defined as:
			C: CWDM (Coarse WDM) application
			n: maximum number of channels supported by the application code
			(i.e. an integer number)
			W: take values S (short-haul), L (long-haul).
			x: maximum number of spans allowed
			y: take values 0 (NRZ 1.25G), 1 (NRZ 2.5G), 2 (NRZ 10G).
			t: take values D (link does not contain any optical amplifier).
			z: take values 1 (1310 nm region for ITU-T G.652 fibre), 2 (ITU-T
			G.652 fibre), 3 (ITU-T G.653 fibre), 5 (ITU-T G.655 fibre).
			The following list of suffixes can be added to these application
			codes:
			F: FEC encoding.
			Since the application codes are very similar to the one from the
			G.959 section most of the fields are reused. The 64 bit OIC field is
