  1. Fiber Access Network • Untuk memenuhi kebutuhan bandwidth yang terus meningkat untuk berbagai layanan bagi pelanggan diperlukan penyediaan “new high-bandwidth access services”. • Optical fiber access menyediakan bandwidth sampai beberapa gigabits per second (Gbps)—dan mungkin akan terus meningkat sejalan dengan kemajuan teknologi. • Konfigurasi jaringan • All optical fiber access network • Point to point (PTP) network • Passive/active optical network (PON/AON) • FTTx • Struktur jaringan berdasarkan penentuan titik konversi sinyal (perubahan dari optik ke twisted pair atau coaxial cable) SM241013 - Pengantar Sistem Telekomunikasi Semester genap 2007-2008 1

  3. Passive/Active Optical Network Central Office / Head End PS/AS PS/AS PS = Passive Splitter AS = Active Splitter SM241013 - Pengantar Sistem Telekomunikasi Semester genap 2007-2008 3

  4. Passive Optical Network (PON) • Does not contain any electronics between the central office/headend switch and the customer-premises equipment • The entire down­stream bandwidth is transmitted to the power splitter and delivered to each subscriber • The customer-premises equipment contains optical transceivers that switch on and off during the allocated time slots and select their content; this prevents them from accessing content not intended for them • Each splitter typically splits a fiber into 16, 32, or 64 fibers, depending on the manufacturer, and several splitters can be aggregated in a single cabinet SM241013 - Pengantar Sistem Telekomunikasi Semester genap 2007-2008

  5. Active Optical Network (AON) OLT Switch • All subscriber content is transmitted to the aggregation switch and then distributed to the appropriate subscribers only • At the switch, all content is converted from an optical signal to an electrical signal, separated from other content, and converted again to an optical signal and delivered appropriately over separate fibers to each destination • Active networks have additional intelligence located closer to the subscriber that can reduce latency, flexibly add bandwidth, isolate faults, switch, schedule and queue traffic— and maximize bandwidth utilization between the switch aggregator and central office SM241013 - Pengantar Sistem Telekomunikasi Semester genap 2007-2008

  9. Fiber To The Home (FTTH) Distribution Feeder Central Office Optical Fiber Cable Aplikasi : All optical fiber access network Network access point Distance 0 Up to 20 km SM241013 - Pengantar Sistem Telekomunikasi Semester genap 2007-2008 9

  10. Hybrid Fiber Coaxial (HFC) Central Office / Head End Coaxial cable Hybrid Node Optical Fibers Coaxial cable Hybrid Node • HFC adalah jaringan akses yang mengkombinasikan coaxial dan fiber optik • Hybrid node : mengkonversi sinyal optik menjadi sinyal elektris untuk ditransmisikan ke user terminal melalui kabel coaxial SM241013 - Pengantar Sistem Telekomunikasi Semester genap 2007-2008

  12. Powerline Communication (PLC), also known as Broadband Over Powerline (BPL) is a technique for sending high speed data through existing powerline as transmission medium. PLC creates a high speed data communications network using the medium and low voltage electric distribution grids which connects consumers to the Internet through any electric socket in the consumers home. Powerline is the worlds largest existing wired infrastructure. Power Line Communication (PLC)
