Hi Love kumar,
Thank you so much for such valuable information.
I have read both papers, both are useful and important specially the second one:
Time- and Wavelength-Division Multiplexed Passive Optical Network (TWDM-PON) for Next-Generation PON Stage 2 (NG-PON2) of
JOURNAL OF LIGHTWAVE TECHNOLOGY.
By reading this we get valuable information about time- and wavelength-division multiplexed passive
optical network (TWDM-PON), tunable receiver, tunable transmitter.

I want to share some important information about TWDM to all of you :
Among all of the proposals for different technologies of NGPON2, TWDM-PON
has attracted the majority support from global vendors and was
selected by the FSAN community in the April 2012 meeting as a
primary solution to NG-PON2. TWDM-PON increases the aggregate
PON rate by stacking XG-PONs via multiple pairs of
wavelengths. An XG-PON system offers the access rates of 10
Gb/s in downstream and 2.5 Gb/s in upstream. A TWDM-PON
system with four pairs of wavelengths is able to provide 40 Gb/s
and 10 Gb/s in downstream and upstream, respectively. Each
TWDM-PON ONU can provide peak rates up to 10 Gb/s downstream
and 2.5 Gb/s upstream. This meets the rate requirements
of NG-PON2.
Hence TWDM is most important technologies for NGPON2.

Thanks
