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!
2
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
3
Municipalities Utilities CLECs Private companies Battleground for telcos and CATV companies
4
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?
5
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 ©2006
6
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? 7
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
8
US: 6 million homes passed (Jan, ‘06) 1,000,000 connected Still a drop in the bucket! Data from Render, Vanderslice and Associates, 2006
9
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!

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

FTTT
Arsitektur FTTx Modus Aplikasi Jaringan FTTX. 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: 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. 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.
Arsitektur FTTx 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. 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. Sehingga FTTT bisa dianalogikan sebagai pengganti ODP ( FTTC ) atau TB ( FTTH )

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
Fiber To The Zone •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
ZONE
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
•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.

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
