

FTTH: fiber to the home



FTTP: fiber to the

premises



FTTC: fiber to the curb



FTTN: Fiber to the node



FTTx: for those who

can’t decide what to

call it or are referring to

all varieties!

(3)



Mostly a telco issue

◦

Telcos have many aging cable

plants

◦

CATV companies have HFC

networks in place

◦

Competitive carriers now

install own fiber

◦

Telcos fighting for exclusive

rights



Private companies



Battleground for telcos

and CATV companies

(5)



Where is the bulk of telephone cabling?

◦

10% is long distance

◦

10% is local loop (metropolitan)

◦

80% is subscriber loop



Long distance and local loop are virtually

all fiber



Is FTTx just completing the system?

(6)



Telcos are suffering with aging

copper cable plants



Telcos are losing broadband

customers to CATV and landline

customers to cell phones and VoIP



New services are becoming available

to enhance revenue - and customers

demand them



Regulations changed sharing issues



New technology (PON) and cheaper

components makes FTTx cheaper

Fiber Optic Association & VDV Academy

(7)



Many telcos are realizing

that the alternatives to FTTx

are inadequate for future

bandwidth needs:

◦

DSL won’t have the bandwidth

◦

Wireless won’t have the

bandwidth

◦

BPL won’t have the bandwidth



Eventually they will have to

go FTTx, so why put off the

inevitable?

(8)



Homeowners: for high speed Internet access

and video downloads



Home Builders: FTTx adds value (and profit)

to their homes



Hardware Providers



Service Providers: IPTV, HDTV, video on

demand

(9)



US: 6 million

homes passed

(Jan, ‘06)



1,000,000

connected



Still a drop in

the bucket!



Data from Render,

Vanderslice and

Associates, 2006

(10)



Contractors are doing FTTx installs for

Verizon and others



While few electrical contractors do residential

electrical, homes with structured cabling offer

double the work and potential profit!



FTTx will affect the commercial fiber market -

fiber is cheaper!

(11)

(12)



Home run - fiber from CO to every home



Active star - local switch then fiber to every

home



Passive optical network (PON) - use splitter

near customer share fiber to CO



WDM PON - PON but with each customer

having a specified wavelength



All based on standard SM fiber

Modus Aplikasi Jaringan FTTX.

1. Fiber To The Building.

TKO terletak didalam gedung dan biasanya terletak pada ruang telekomunikasi di basement atau tersebar dibeberapa lantai, terminal pelanggan dihubungkan dengan TKO melalui kabel tembaga Indor atau IKG, FTTB dapat dianalogikan dengan Daerah Catu Langsung pada jaringan kabel tembaga.

Jaringan kabel lokal fiber Optik ( Fiber to The X ) paling sedikitnya terdapat 2 perangkat aktif ( Opto Elektrik ) yang dipasang di Central Office dan yang satu lagi dipasang di dekat dan atau di lokasi pelanggan.

Berdasarkan lokasi penempatan perangkat aktif yang dipasang didekat dan atau dilokasi pelanggan maka terdapat beberapa Konfigurasi sbb:

Arsitektur FTTx

2. Fiber To The Zone

TKO terletak disuatu tempat diluar bangunan, biasanya berupa kabinet yang ditempatkan di pinggir jalan sebagai mana biasanya RK, terminal pelanggan dihubungkan dengan TKO melalui kabel tembaga hingga beberapa kilometer, FTTZ dapat dianalogikan sebagai pengganti RK.

(31)

3. Fiber To The Curb.

TKO terletak disuatu tempat diluar bangunan, baik didalam kabinet, diatas tiang maupun di Manhole, terminal pelanggan dihubungkan dengan TKO melalui kabel tembaga hingga beberapa ratus meter saja, FTTC dapat dianalogikan sebagai pengganti Titik Pembagi.

Arsitektur FTTx

4. Fiber To The Home

TKO terletak didalam rumah pelanggan, terminal pelanggan dihubungkan dengan TKO melalui kabel tembaga Indoor atau IKR hingga beberapa puluh meter saja, FTTH dapat dianalogikan sebagai pengganti Terminal Blok ( TB ).

5. Fiber To The Tower.

• TKO terletak didalam shelter dari pada Tower, terminal equipment system GSM/ CDMA dihubungkan dengan TKO melalui kabel tembaga Indoor hingga beberapa meter saja

• Jaringan kabel FO yang mencatu Tower sbb:

 Kabel FO Drop kalau lokasi tower perkotaan.

 Kabel FO Distribusi kalau lokasi tower di pinggiran kota.

Berdasarkan perbedaan letak

TKO (Titik Konversi sinyal Optik) :

– Fiber To The Building (FTTB)

– Fiber To The Zone (FTTZ)

– Fiber To The Curb (FTTC)

– Fiber To The Home (FTTH)

Fiber to The Building

•TKO terletak di dalam

gedung dan biasanya di

ruang telekomunikasi yang

di

sediakan

oleh

management

Building(biasanya

di

Basement)

•Terminal

pelanggan

dihubungkan dengan TKO

melalui kabel optik atau

tembaga

(disesuaikan

(34)

•Titik sambunga dengan TKO terletak di outdoor(di luar bangunan)

baik berbentuk kabinet dengan kapasitas besar

•Terminal pelanggan dengan TKO melalui jaringan kabel optik

hingga beberapa kilometer,

•FTTZ dapat digambarkan sebagai daerah perumahan yang telah

fix/tetap yang letaknya jauh dari sentral atau infrastructur duct pada

area tersebut

Fiber To The Zone

(35)

Modus Aplikasi FTTC

Fiber To The Curb

• Titik sambungan core

optik berada di luar

bangunan berada dalam

cabinet denan kapasitas

terbatas ( , 120 ss).

•Terminal

pelanggan

yang terhubungan dengan

kabel FO berjarak kurang

dari 200 meter

•FTTC

dapat

di

analogikan

sebagai

pengganti ODP.

•FTTC dapat diterapkan

bagi pelanggan bisnis

yang letaknya terkumpul

dalam satu area tunggal

•Untuk ONT, yang memiliki IAD tertanam di ONT dapat menyediakan interface fungsi POTS.

•Untuk ONU, dilakukan dua cara untuk memberikan layanan VOIP:

•Melalui IAD eksternal atau HG,

•Atau fungsi IAD tertanam di ONU yang menyediakan POTS secara langsung.

memungkinkan

Di sisi OLT untuk jaringan IPTV menggunakan SNI, dihubungkan dengan dua cara :

a. Melalui BRAS, yang lebih mudah untuk mengelola tetapi

batas kinerja multicast

b. Koneksi langsung, yang menjamin kinerja yang akan lebih baik
