Hello mohammed ridha al-shamapti,

Fiber to the home is a technology for home delivery of communication signal over the fiber, this is to provide High speed connectivity to the end user which is somewhat problem to achieve using copper or coaxial cable because of low data rate. One specific kind of fiber named band insensitive fiber get a best application here. for research purpose you will get various paper by googling regarding this topic.

Hi,
Wavelength Division Multiplexed PON
There are many concepts concerning how WDM-PON may
be implemented and several were studied in the context of
NG-PON2. They are Externally seeded WDM-PON,Wavelength re-use WDM-PON , Tunable WDM-PON, Ultra-dense Coherent WDM-PON.
WDM PON uses multiple wavelengths to
provision bandwidth to ONUs, while OFDM PON employs a number of orthogonal
subcarriers to transmit traffic from/to ONUs.With the WDM or OFDM technology,
these PONs are potentially able to provide higher than 40Gb/s data rate and even
Tera bps data rate. due to the high system cost.
WDM PON allows each user being dedicated with one or
more wavelengths, thus allowing each subscriber to access the full bandwidth
accommodated by the wavelengths.

Here are links for WDM-PON as:

Hi
i would like to add that there are three types of PON system, namely B-PON, G-PON and GE-PON. the GE-PON system has been developed and implemented it as a cost-effective optical access system with a high throughput. With a PON system, optical fibers and transmission devices are shared by multiple customers in order to provide FTTH services at low cost. This means that even when accommodating several customers at once, each customer can be provided with high-speed data transmission at a maximum data rate of 100 Mbit/s.
Once fibers are deployed in the field, it would be a critical issue how to migrate to WDM-PON because current Time Division Multiplexing (TDM)- based PON solutions cannot exploit the huge bandwidth of the optical fibers and therefore will have difficulties in meeting ever-increasing demands for higher bandwidth by future network applications.

I hope this will be helpful.
Thanks

I would also like to add that With the recent advancements in access networks the TDM PON, like Ethernet passive optical network (EPON) and Gigabit Passive optical network (GPON), are now widely used as optical access network solutions to distribute reasonably high bandwidths to the customers through an optical fiber network infrastructure. Researchers are aiming at optical access network concepts known as hybrid WDM/TDM access passive optical networks.
Various techniques and components of the network are designed to achieve high data rate transmission to large bandwidth such as tuneable optical add/drop multiplexer (OADM) , colorless ONU , selfhomodyne and differential coding , a reflective semiconductor optical amplifier (SOA) and Bragg reflectors. The passive optical networks are constituted of a centralized
OLT located in the central office and a number of ONUs located at the users premises to some distance away from the OLT.

I hope this is useful

Hi Hamza Ali Abbas Khan,
I agree to your points that there are three basic types of PON as APON, BPON and GPON.
The use of ATM-based PON (APON and BPON), the achieved upstream and downstream aggregate bandwidths were in the order of
155 Mbit/s up to 622 Mbit/s. Later, the use of time division multiplexing (TDM) permitted
achieving capacities around 1.2 Gbit/s and 2.5 Gbit/s (downstream & upstream) according with
the ITU-T G.984 G-PON standard. Advanced high-speed TDM based optical access systems
up to 10Gbit/s for downstream and 2.5 upstream (XG-PON1) or 10Gbit/s/ for both downstream
and upstream (XG-PON2), according with the ITU-T G.987 G-PON standard, have been
developed and some field trials have been reported. Currently, standardized specifications by
ITU exist for ATM-based PON (APON and BPON), gigabit-capable PON (GPON) and XG-PON
and Ethernet PON (EPON) and 10G-EPON by IEEE.

For several years FSAN and IEEE have been working on the new international standard ITU-T
G.989: 40-Gigabit-capable passive optical networks (NG-PON2) which general requirements
have been defined on ITU-T G989.1 standard by March of 2013. However the PMD (ITU-T
G989.2) and TC layer requirements (ITU-T G989.3) are still being discussed and are expected
to be published soon.

Further research are going towards Next Generation PON: NGPON1 and NGPON2.
Hybrid TDM and WDM PON are latest type of PON recommended by ITU-T.
Thanks,
